SCR is the core of NOx purification, but the amount of urea injection needs to be precisely controlled to avoid insufficient NH₃ (low NOx conversion rate) or excessive NH₃ (NH₃ escape).\u003c\/p\u003e\n\u003cp\u003e2. ASC is a supplement to SCR to solve the problem of NH₃ escape, especially suitable for scenarios where regulations have strict restrictions on NH₃ emissions (such as National VI b stage).\u003c\/p\u003e\n\u003cp\u003e3. Collaborative design: SCR and ASC need to match exhaust flow rate and temperature window (ASC operating temperature is usually 200-450°C) to ensure overall efficiency.\u003c\/p\u003e\n\u003cp\u003eFAQ on SCR and SCR+ASC catalytic conversion reaction of diesel vehicles\u003c\/p\u003e\n\u003cp\u003e1. What are SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR (Selective Catalytic Reduction): By injecting urea solution into the exhaust gas, urea decomposes to produce ammonia (NH₃). Under the action of the catalyst, ammonia selectively reduces nitrogen oxides (NOₓ) to nitrogen (N₂) and water (H₂O), mainly used to reduce NOₓ emissions in diesel vehicle exhaust.\u003c\/p\u003e\n\u003cp\u003eSCR+ASC (Ammonia Escape Catalytic Converter): Add an ASC module on the basis of SCR. ASC can catalytically oxidize excess ammonia (ammonia escape) after the SCR reaction into nitrogen and water, further reducing ammonia pollution to the environment.\u003c\/p\u003e\n\u003cp\u003e2. What is the core difference between SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR only reduces NOₓ, while SCR+ASC can not only reduce NOₓ, but also eliminate ammonia that may escape from the SCR system, meeting stricter NOₓ and NH₃ emission limits.\u003c\/p\u003e\n\u003cp\u003e3. What are the advantages of SCR+ASC?\u003cbr\u003eReduce the pollution of ammonia escape to the atmosphere (such as avoiding the formation of ammonium salt particles);\u003cbr\u003eMeet more stringent emission regulations (such as controlling NOₓ and NH₃ emissions at the same time);\u003cbr\u003eImprove the overall efficiency of the system and avoid ammonia waste.\u003c\/p\u003e\n\u003cp\u003e4. In what scenarios is SCR+ASC suitable?\u003cbr\u003eIn areas with strict emission regulations (such as National VI and above);\u003cbr\u003eApplication scenarios with extremely high requirements for exhaust emissions, such as urban buses, logistics transport vehicles, etc.\u003c\/p\u003e\n\u003cp\u003e5. What are the precautions for the maintenance of both?\u003cbr\u003eSCR: Regularly check whether the urea injection system is blocked and monitor the activity of the catalyst (to avoid high-temperature sintering or poisoning).\u003cbr\u003eSCR+ASC: In addition to the maintenance of SCR, it is necessary to pay extra attention to whether the ASC module is blocked or the catalyst fails, and regularly clean up impurities such as carbon deposits.\u003c\/p\u003e\n\u003cp\u003e6. How is the emission effect compared?\u003c\/p\u003e\n\u003cp\u003eSCR: Only control NOₓ emissions to within the limit;\u003c\/p\u003e\n\u003cp\u003eSCR+ASC: While controlling NOₓ, NH₃ emissions are also reduced to an extremely low level, which is more environmentally friendly.\u003c\/p\u003e\n\u003cp\u003e7. How to solve the ammonia slip problem in SCR?\u003c\/p\u003e\n\u003cp\u003eThrough the SCR+ASC system, the catalyst of the ASC module (such as precious metal Pt\/Pd) is used to catalytically oxidize the escaped ammonia into harmless nitrogen and water.\u003c\/p\u003e\n\u003cp\u003e8. What factors affect the life of the catalyst?\u003c\/p\u003e\n\u003cp\u003eTemperature: Too high a temperature (such as \u0026amp;gt; 600℃) may cause the catalyst to sinter and deactivate;\u003c\/p\u003e\n\u003cp\u003eUrea quality: Impurities in inferior urea (such as biuret) will contaminate the catalyst;\u003c\/p\u003e\n\u003cp\u003eSulfur content: Sulfur in fuel or urea will poison the catalyst and shorten its life. Generally, the life of SCR catalyst is 2-5 years, and SCR+ASC requires comprehensive maintenance to extend the overall life.\u003c\/p\u003e\n\u003cstyle\u003e\n        table {\n            border-collapse: collapse;\n            width: 600px;

Collaborative design: SCR and ASC need to match exhaust flow rate and temperature window (ASC operating temperature is usually 200-450°C) to ensure overall efficiency.\u003c\/p\u003e\n\u003cp\u003eFAQ on SCR and SCR+ASC catalytic conversion reaction of diesel vehicles\u003c\/p\u003e\n\u003cp\u003e1. What are SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR (Selective Catalytic Reduction): By injecting urea solution into the exhaust gas, urea decomposes to produce ammonia (NH₃). Under the action of the catalyst, ammonia selectively reduces nitrogen oxides (NOₓ) to nitrogen (N₂) and water (H₂O), mainly used to reduce NOₓ emissions in diesel vehicle exhaust.\u003c\/p\u003e\n\u003cp\u003eSCR+ASC (Ammonia Escape Catalytic Converter): Add an ASC module on the basis of SCR. ASC can catalytically oxidize excess ammonia (ammonia escape) after the SCR reaction into nitrogen and water, further reducing ammonia pollution to the environment.\u003c\/p\u003e\n\u003cp\u003e2. What is the core difference between SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR only reduces NOₓ, while SCR+ASC can not only reduce NOₓ, but also eliminate ammonia that may escape from the SCR system, meeting stricter NOₓ and NH₃ emission limits.\u003c\/p\u003e\n\u003cp\u003e3. What are the advantages of SCR+ASC?\u003cbr\u003eReduce the pollution of ammonia escape to the atmosphere (such as avoiding the formation of ammonium salt particles);\u003cbr\u003eMeet more stringent emission regulations (such as controlling NOₓ and NH₃ emissions at the same time);\u003cbr\u003eImprove the overall efficiency of the system and avoid ammonia waste.\u003c\/p\u003e\n\u003cp\u003e4. In what scenarios is SCR+ASC suitable?\u003cbr\u003eIn areas with strict emission regulations (such as National VI and above);\u003cbr\u003eApplication scenarios with extremely high requirements for exhaust emissions, such as urban buses, logistics transport vehicles, etc.\u003c\/p\u003e\n\u003cp\u003e5. What are the precautions for the maintenance of both?\u003cbr\u003eSCR: Regularly check whether the urea injection system is blocked and monitor the activity of the catalyst (to avoid high-temperature sintering or poisoning).\u003cbr\u003eSCR+ASC: In addition to the maintenance of SCR, it is necessary to pay extra attention to whether the ASC module is blocked or the catalyst fails, and regularly clean up impurities such as carbon deposits.\u003c\/p\u003e\n\u003cp\u003e6. How is the emission effect compared?\u003c\/p\u003e\n\u003cp\u003eSCR: Only control NOₓ emissions to within the limit;\u003c\/p\u003e\n\u003cp\u003eSCR+ASC: While controlling NOₓ, NH₃ emissions are also reduced to an extremely low level, which is more environmentally friendly.\u003c\/p\u003e\n\u003cp\u003e7. How to solve the ammonia slip problem in SCR?\u003c\/p\u003e\n\u003cp\u003eThrough the SCR+ASC system, the catalyst of the ASC module (such as precious metal Pt\/Pd) is used to catalytically oxidize the escaped ammonia into harmless nitrogen and water.\u003c\/p\u003e\n\u003cp\u003e8. What factors affect the life of the catalyst?\u003c\/p\u003e\n\u003cp\u003eTemperature: Too high a temperature (such as \u0026amp;gt; 600℃) may cause the catalyst to sinter and deactivate;\u003c\/p\u003e\n\u003cp\u003eUrea quality: Impurities in inferior urea (such as biuret) will contaminate the catalyst;\u003c\/p\u003e\n\u003cp\u003eSulfur content: Sulfur in fuel or urea will poison the catalyst and shorten its life. Generally, the life of SCR catalyst is 2-5 years, and SCR+ASC requires comprehensive maintenance to extend the overall life.\u003c\/p\u003e\n\u003cstyle\u003e\n        table {\n            border-collapse: collapse;\n            width: 600px;

SCR is the core of NOx purification, but the amount of urea injection needs to be precisely controlled to avoid insufficient NH₃ (low NOx conversion rate) or excessive NH₃ (NH₃ escape).\u003c\/p\u003e\n\u003cp\u003e2. ASC is a supplement to SCR to solve the problem of NH₃ escape, especially suitable for scenarios where regulations have strict restrictions on NH₃ emissions (such as National VI b stage).\u003c\/p\u003e\n\u003cp\u003e3. Collaborative design: SCR and ASC need to match exhaust flow rate and temperature window (ASC operating temperature is usually 200-450°C) to ensure overall efficiency.\u003c\/p\u003e\n\u003cp\u003eFAQ on SCR and SCR+ASC catalytic conversion reaction of diesel vehicles\u003c\/p\u003e\n\u003cp\u003e1. What are SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR (Selective Catalytic Reduction): By injecting urea solution into the exhaust gas, urea decomposes to produce ammonia (NH₃). Under the action of the catalyst, ammonia selectively reduces nitrogen oxides (NOₓ) to nitrogen (N₂) and water (H₂O), mainly used to reduce NOₓ emissions in diesel vehicle exhaust.\u003c\/p\u003e\n\u003cp\u003eSCR+ASC (Ammonia Escape Catalytic Converter): Add an ASC module on the basis of SCR. ASC can catalytically oxidize excess ammonia (ammonia escape) after the SCR reaction into nitrogen and water, further reducing ammonia pollution to the environment.\u003c\/p\u003e\n\u003cp\u003e2. What is the core difference between SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR only reduces NOₓ, while SCR+ASC can not only reduce NOₓ, but also eliminate ammonia that may escape from the SCR system, meeting stricter NOₓ and NH₃ emission limits.\u003c\/p\u003e\n\u003cp\u003e3. What are the advantages of SCR+ASC?\u003cbr\u003eReduce the pollution of ammonia escape to the atmosphere (such as avoiding the formation of ammonium salt particles);\u003cbr\u003eMeet more stringent emission regulations (such as controlling NOₓ and NH₃ emissions at the same time);\u003cbr\u003eImprove the overall efficiency of the system and avoid ammonia waste.\u003c\/p\u003e\n\u003cp\u003e4. In what scenarios is SCR+ASC suitable?\u003cbr\u003eIn areas with strict emission regulations (such as National VI and above);\u003cbr\u003eApplication scenarios with extremely high requirements for exhaust emissions, such as urban buses, logistics transport vehicles, etc.\u003c\/p\u003e\n\u003cp\u003e5. What are the precautions for the maintenance of both?\u003cbr\u003eSCR: Regularly check whether the urea injection system is blocked and monitor the activity of the catalyst (to avoid high-temperature sintering or poisoning).\u003cbr\u003eSCR+ASC: In addition to the maintenance of SCR, it is necessary to pay extra attention to whether the ASC module is blocked or the catalyst fails, and regularly clean up impurities such as carbon deposits.\u003c\/p\u003e\n\u003cp\u003e6. How is the emission effect compared?\u003c\/p\u003e\n\u003cp\u003eSCR: Only control NOₓ emissions to within the limit;\u003c\/p\u003e\n\u003cp\u003eSCR+ASC: While controlling NOₓ, NH₃ emissions are also reduced to an extremely low level, which is more environmentally friendly.\u003c\/p\u003e\n\u003cp\u003e7. How to solve the ammonia slip problem in SCR?\u003c\/p\u003e\n\u003cp\u003eThrough the SCR+ASC system, the catalyst of the ASC module (such as precious metal Pt\/Pd) is used to catalytically oxidize the escaped ammonia into harmless nitrogen and water.\u003c\/p\u003e\n\u003cp\u003e8. What factors affect the life of the catalyst?\u003c\/p\u003e\n\u003cp\u003eTemperature: Too high a temperature (such as \u0026amp;gt; 600℃) may cause the catalyst to sinter and deactivate;\u003c\/p\u003e\n\u003cp\u003eUrea quality: Impurities in inferior urea (such as biuret) will contaminate the catalyst;\u003c\/p\u003e\n\u003cp\u003eSulfur content: Sulfur in fuel or urea will poison the catalyst and shorten its life. Generally, the life of SCR catalyst is 2-5 years, and SCR+ASC requires comprehensive maintenance to extend the overall life.\u003c\/p\u003e\n\u003cstyle\u003e\n        table {\n            border-collapse: collapse;\n            width: 600px;

SCR is the core of NOx purification, but the amount of urea injection needs to be precisely controlled to avoid insufficient NH₃ (low NOx conversion rate) or excessive NH₃ (NH₃ escape).\u003c\/p\u003e\n\u003cp\u003e2. ASC is a supplement to SCR to solve the problem of NH₃ escape, especially suitable for scenarios where regulations have strict restrictions on NH₃ emissions (such as National VI b stage).\u003c\/p\u003e\n\u003cp\u003e3. Collaborative design: SCR and ASC need to match exhaust flow rate and temperature window (ASC operating temperature is usually 200-450°C) to ensure overall efficiency.\u003c\/p\u003e\n\u003cp\u003eFAQ on SCR and SCR+ASC catalytic conversion reaction of diesel vehicles\u003c\/p\u003e\n\u003cp\u003e1. What are SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR (Selective Catalytic Reduction): By injecting urea solution into the exhaust gas, urea decomposes to produce ammonia (NH₃). Under the action of the catalyst, ammonia selectively reduces nitrogen oxides (NOₓ) to nitrogen (N₂) and water (H₂O), mainly used to reduce NOₓ emissions in diesel vehicle exhaust.\u003c\/p\u003e\n\u003cp\u003eSCR+ASC (Ammonia Escape Catalytic Converter): Add an ASC module on the basis of SCR. ASC can catalytically oxidize excess ammonia (ammonia escape) after the SCR reaction into nitrogen and water, further reducing ammonia pollution to the environment.\u003c\/p\u003e\n\u003cp\u003e2. What is the core difference between SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR only reduces NOₓ, while SCR+ASC can not only reduce NOₓ, but also eliminate ammonia that may escape from the SCR system, meeting stricter NOₓ and NH₃ emission limits.\u003c\/p\u003e\n\u003cp\u003e3. What are the advantages of SCR+ASC?\u003cbr\u003eReduce the pollution of ammonia escape to the atmosphere (such as avoiding the formation of ammonium salt particles);\u003cbr\u003eMeet more stringent emission regulations (such as controlling NOₓ and NH₃ emissions at the same time);\u003cbr\u003eImprove the overall efficiency of the system and avoid ammonia waste.\u003c\/p\u003e\n\u003cp\u003e4. In what scenarios is SCR+ASC suitable?\u003cbr\u003eIn areas with strict emission regulations (such as National VI and above);\u003cbr\u003eApplication scenarios with extremely high requirements for exhaust emissions, such as urban buses, logistics transport vehicles, etc.\u003c\/p\u003e\n\u003cp\u003e5. What are the precautions for the maintenance of both?\u003cbr\u003eSCR: Regularly check whether the urea injection system is blocked and monitor the activity of the catalyst (to avoid high-temperature sintering or poisoning).\u003cbr\u003eSCR+ASC: In addition to the maintenance of SCR, it is necessary to pay extra attention to whether the ASC module is blocked or the catalyst fails, and regularly clean up impurities such as carbon deposits.\u003c\/p\u003e\n\u003cp\u003e6. How is the emission effect compared?\u003c\/p\u003e\n\u003cp\u003eSCR: Only control NOₓ emissions to within the limit;\u003c\/p\u003e\n\u003cp\u003eSCR+ASC: While controlling NOₓ, NH₃ emissions are also reduced to an extremely low level, which is more environmentally friendly.\u003c\/p\u003e\n\u003cp\u003e7. How to solve the ammonia slip problem in SCR?\u003c\/p\u003e\n\u003cp\u003eThrough the SCR+ASC system, the catalyst of the ASC module (such as precious metal Pt\/Pd) is used to catalytically oxidize the escaped ammonia into harmless nitrogen and water.\u003c\/p\u003e\n\u003cp\u003e8. What factors affect the life of the catalyst?\u003c\/p\u003e\n\u003cp\u003eTemperature: Too high a temperature (such as \u0026amp;gt; 600℃) may cause the catalyst to sinter and deactivate;\u003c\/p\u003e\n\u003cp\u003eUrea quality: Impurities in inferior urea (such as biuret) will contaminate the catalyst;\u003c\/p\u003e\n\u003cp\u003eSulfur content: Sulfur in fuel or urea will poison the catalyst and shorten its life. Generally, the life of SCR catalyst is 2-5 years, and SCR+ASC requires comprehensive maintenance to extend the overall life.\u003c\/p\u003e\n\u003cstyle\u003e\n        table {\n            border-collapse: collapse;\n            width: 600px;

What are SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR (Selective Catalytic Reduction): By injecting urea solution into the exhaust gas, urea decomposes to produce ammonia (NH₃). Under the action of the catalyst, ammonia selectively reduces nitrogen oxides (NOₓ) to nitrogen (N₂) and water (H₂O), mainly used to reduce NOₓ emissions in diesel vehicle exhaust.\u003c\/p\u003e\n\u003cp\u003eSCR+ASC (Ammonia Escape Catalytic Converter): Add an ASC module on the basis of SCR. ASC can catalytically oxidize excess ammonia (ammonia escape) after the SCR reaction into nitrogen and water, further reducing ammonia pollution to the environment.\u003c\/p\u003e\n\u003cp\u003e2. What is the core difference between SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR only reduces NOₓ, while SCR+ASC can not only reduce NOₓ, but also eliminate ammonia that may escape from the SCR system, meeting stricter NOₓ and NH₃ emission limits.\u003c\/p\u003e\n\u003cp\u003e3. What are the advantages of SCR+ASC?\u003cbr\u003eReduce the pollution of ammonia escape to the atmosphere (such as avoiding the formation of ammonium salt particles);\u003cbr\u003eMeet more stringent emission regulations (such as controlling NOₓ and NH₃ emissions at the same time);\u003cbr\u003eImprove the overall efficiency of the system and avoid ammonia waste.\u003c\/p\u003e\n\u003cp\u003e4. In what scenarios is SCR+ASC suitable?\u003cbr\u003eIn areas with strict emission regulations (such as National VI and above);\u003cbr\u003eApplication scenarios with extremely high requirements for exhaust emissions, such as urban buses, logistics transport vehicles, etc.\u003c\/p\u003e\n\u003cp\u003e5. What are the precautions for the maintenance of both?\u003cbr\u003eSCR: Regularly check whether the urea injection system is blocked and monitor the activity of the catalyst (to avoid high-temperature sintering or poisoning).\u003cbr\u003eSCR+ASC: In addition to the maintenance of SCR, it is necessary to pay extra attention to whether the ASC module is blocked or the catalyst fails, and regularly clean up impurities such as carbon deposits.\u003c\/p\u003e\n\u003cp\u003e6. How is the emission effect compared?\u003c\/p\u003e\n\u003cp\u003eSCR: Only control NOₓ emissions to within the limit;\u003c\/p\u003e\n\u003cp\u003eSCR+ASC: While controlling NOₓ, NH₃ emissions are also reduced to an extremely low level, which is more environmentally friendly.\u003c\/p\u003e\n\u003cp\u003e7. How to solve the ammonia slip problem in SCR?\u003c\/p\u003e\n\u003cp\u003eThrough the SCR+ASC system, the catalyst of the ASC module (such as precious metal Pt\/Pd) is used to catalytically oxidize the escaped ammonia into harmless nitrogen and water.\u003c\/p\u003e\n\u003cp\u003e8. What factors affect the life of the catalyst?\u003c\/p\u003e\n\u003cp\u003eTemperature: Too high a temperature (such as \u0026amp;gt; 600℃) may cause the catalyst to sinter and deactivate;\u003c\/p\u003e\n\u003cp\u003eUrea quality: Impurities in inferior urea (such as biuret) will contaminate the catalyst;\u003c\/p\u003e\n\u003cp\u003eSulfur content: Sulfur in fuel or urea will poison the catalyst and shorten its life. Generally, the life of SCR catalyst is 2-5 years, and SCR+ASC requires comprehensive maintenance to extend the overall life.\u003c\/p\u003e\n\u003cstyle\u003e\n        table {\n            border-collapse: collapse;\n            width: 600px;

SCR is the core of NOx purification, but the amount of urea injection needs to be precisely controlled to avoid insufficient NH₃ (low NOx conversion rate) or excessive NH₃ (NH₃ escape).\u003c\/p\u003e\n\u003cp\u003e2. ASC is a supplement to SCR to solve the problem of NH₃ escape, especially suitable for scenarios where regulations have strict restrictions on NH₃ emissions (such as National VI b stage).\u003c\/p\u003e\n\u003cp\u003e3. Collaborative design: SCR and ASC need to match exhaust flow rate and temperature window (ASC operating temperature is usually 200-450°C) to ensure overall efficiency.\u003c\/p\u003e\n\u003cp\u003eFAQ on SCR and SCR+ASC catalytic conversion reaction of diesel vehicles\u003c\/p\u003e\n\u003cp\u003e1. What are SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR (Selective Catalytic Reduction): By injecting urea solution into the exhaust gas, urea decomposes to produce ammonia (NH₃). Under the action of the catalyst, ammonia selectively reduces nitrogen oxides (NOₓ) to nitrogen (N₂) and water (H₂O), mainly used to reduce NOₓ emissions in diesel vehicle exhaust.\u003c\/p\u003e\n\u003cp\u003eSCR+ASC (Ammonia Escape Catalytic Converter): Add an ASC module on the basis of SCR. ASC can catalytically oxidize excess ammonia (ammonia escape) after the SCR reaction into nitrogen and water, further reducing ammonia pollution to the environment.\u003c\/p\u003e\n\u003cp\u003e2. What is the core difference between SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR only reduces NOₓ, while SCR+ASC can not only reduce NOₓ, but also eliminate ammonia that may escape from the SCR system, meeting stricter NOₓ and NH₃ emission limits.\u003c\/p\u003e\n\u003cp\u003e3. What are the advantages of SCR+ASC?\u003cbr\u003eReduce the pollution of ammonia escape to the atmosphere (such as avoiding the formation of ammonium salt particles);\u003cbr\u003eMeet more stringent emission regulations (such as controlling NOₓ and NH₃ emissions at the same time);\u003cbr\u003eImprove the overall efficiency of the system and avoid ammonia waste.\u003c\/p\u003e\n\u003cp\u003e4. In what scenarios is SCR+ASC suitable?\u003cbr\u003eIn areas with strict emission regulations (such as National VI and above);\u003cbr\u003eApplication scenarios with extremely high requirements for exhaust emissions, such as urban buses, logistics transport vehicles, etc.\u003c\/p\u003e\n\u003cp\u003e5. What are the precautions for the maintenance of both?\u003cbr\u003eSCR: Regularly check whether the urea injection system is blocked and monitor the activity of the catalyst (to avoid high-temperature sintering or poisoning).\u003cbr\u003eSCR+ASC: In addition to the maintenance of SCR, it is necessary to pay extra attention to whether the ASC module is blocked or the catalyst fails, and regularly clean up impurities such as carbon deposits.\u003c\/p\u003e\n\u003cp\u003e6. How is the emission effect compared?\u003c\/p\u003e\n\u003cp\u003eSCR: Only control NOₓ emissions to within the limit;\u003c\/p\u003e\n\u003cp\u003eSCR+ASC: While controlling NOₓ, NH₃ emissions are also reduced to an extremely low level, which is more environmentally friendly.\u003c\/p\u003e\n\u003cp\u003e7. How to solve the ammonia slip problem in SCR?\u003c\/p\u003e\n\u003cp\u003eThrough the SCR+ASC system, the catalyst of the ASC module (such as precious metal Pt\/Pd) is used to catalytically oxidize the escaped ammonia into harmless nitrogen and water.\u003c\/p\u003e\n\u003cp\u003e8. What factors affect the life of the catalyst?\u003c\/p\u003e\n\u003cp\u003eTemperature: Too high a temperature (such as \u0026amp;gt; 600℃) may cause the catalyst to sinter and deactivate;\u003c\/p\u003e\n\u003cp\u003eUrea quality: Impurities in inferior urea (such as biuret) will contaminate the catalyst;\u003c\/p\u003e\n\u003cp\u003eSulfur content: Sulfur in fuel or urea will poison the catalyst and shorten its life. Generally, the life of SCR catalyst is 2-5 years, and SCR+ASC requires comprehensive maintenance to extend the overall life.\u003c\/p\u003e\n\u003cstyle\u003e\n        table {\n            border-collapse: collapse;\n            width: 600px;

SCR is the core of NOx purification, but the amount of urea injection needs to be precisely controlled to avoid insufficient NH₃ (low NOx conversion rate) or excessive NH₃ (NH₃ escape).\u003c\/p\u003e\n\u003cp\u003e2. ASC is a supplement to SCR to solve the problem of NH₃ escape, especially suitable for scenarios where regulations have strict restrictions on NH₃ emissions (such as National VI b stage).\u003c\/p\u003e\n\u003cp\u003e3. Collaborative design: SCR and ASC need to match exhaust flow rate and temperature window (ASC operating temperature is usually 200-450°C) to ensure overall efficiency.\u003c\/p\u003e\n\u003cp\u003eFAQ on SCR and SCR+ASC catalytic conversion reaction of diesel vehicles\u003c\/p\u003e\n\u003cp\u003e1. What are SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR (Selective Catalytic Reduction): By injecting urea solution into the exhaust gas, urea decomposes to produce ammonia (NH₃). Under the action of the catalyst, ammonia selectively reduces nitrogen oxides (NOₓ) to nitrogen (N₂) and water (H₂O), mainly used to reduce NOₓ emissions in diesel vehicle exhaust.\u003c\/p\u003e\n\u003cp\u003eSCR+ASC (Ammonia Escape Catalytic Converter): Add an ASC module on the basis of SCR. ASC can catalytically oxidize excess ammonia (ammonia escape) after the SCR reaction into nitrogen and water, further reducing ammonia pollution to the environment.\u003c\/p\u003e\n\u003cp\u003e2. What is the core difference between SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR only reduces NOₓ, while SCR+ASC can not only reduce NOₓ, but also eliminate ammonia that may escape from the SCR system, meeting stricter NOₓ and NH₃ emission limits.\u003c\/p\u003e\n\u003cp\u003e3. What are the advantages of SCR+ASC?\u003cbr\u003eReduce the pollution of ammonia escape to the atmosphere (such as avoiding the formation of ammonium salt particles);\u003cbr\u003eMeet more stringent emission regulations (such as controlling NOₓ and NH₃ emissions at the same time);\u003cbr\u003eImprove the overall efficiency of the system and avoid ammonia waste.\u003c\/p\u003e\n\u003cp\u003e4. In what scenarios is SCR+ASC suitable?\u003cbr\u003eIn areas with strict emission regulations (such as National VI and above);\u003cbr\u003eApplication scenarios with extremely high requirements for exhaust emissions, such as urban buses, logistics transport vehicles, etc.\u003c\/p\u003e\n\u003cp\u003e5. What are the precautions for the maintenance of both?\u003cbr\u003eSCR: Regularly check whether the urea injection system is blocked and monitor the activity of the catalyst (to avoid high-temperature sintering or poisoning).\u003cbr\u003eSCR+ASC: In addition to the maintenance of SCR, it is necessary to pay extra attention to whether the ASC module is blocked or the catalyst fails, and regularly clean up impurities such as carbon deposits.\u003c\/p\u003e\n\u003cp\u003e6. How is the emission effect compared?\u003c\/p\u003e\n\u003cp\u003eSCR: Only control NOₓ emissions to within the limit;\u003c\/p\u003e\n\u003cp\u003eSCR+ASC: While controlling NOₓ, NH₃ emissions are also reduced to an extremely low level, which is more environmentally friendly.\u003c\/p\u003e\n\u003cp\u003e7. How to solve the ammonia slip problem in SCR?\u003c\/p\u003e\n\u003cp\u003eThrough the SCR+ASC system, the catalyst of the ASC module (such as precious metal Pt\/Pd) is used to catalytically oxidize the escaped ammonia into harmless nitrogen and water.\u003c\/p\u003e\n\u003cp\u003e8. What factors affect the life of the catalyst?\u003c\/p\u003e\n\u003cp\u003eTemperature: Too high a temperature (such as \u0026amp;gt; 600℃) may cause the catalyst to sinter and deactivate;\u003c\/p\u003e\n\u003cp\u003eUrea quality: Impurities in inferior urea (such as biuret) will contaminate the catalyst;\u003c\/p\u003e\n\u003cp\u003eSulfur content: Sulfur in fuel or urea will poison the catalyst and shorten its life. Generally, the life of SCR catalyst is 2-5 years, and SCR+ASC requires comprehensive maintenance to extend the overall life.\u003c\/p\u003e\n\u003cstyle\u003e\n        table {\n            border-collapse: collapse;\n            width: 600px;

What are SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR (Selective Catalytic Reduction): By injecting urea solution into the exhaust gas, urea decomposes to produce ammonia (NH₃). Under the action of the catalyst, ammonia selectively reduces nitrogen oxides (NOₓ) to nitrogen (N₂) and water (H₂O), mainly used to reduce NOₓ emissions in diesel vehicle exhaust.\u003c\/p\u003e\n\u003cp\u003eSCR+ASC (Ammonia Escape Catalytic Converter): Add an ASC module on the basis of SCR. ASC can catalytically oxidize excess ammonia (ammonia escape) after the SCR reaction into nitrogen and water, further reducing ammonia pollution to the environment.\u003c\/p\u003e\n\u003cp\u003e2. What is the core difference between SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR only reduces NOₓ, while SCR+ASC can not only reduce NOₓ, but also eliminate ammonia that may escape from the SCR system, meeting stricter NOₓ and NH₃ emission limits.\u003c\/p\u003e\n\u003cp\u003e3. What are the advantages of SCR+ASC?\u003cbr\u003eReduce the pollution of ammonia escape to the atmosphere (such as avoiding the formation of ammonium salt particles);\u003cbr\u003eMeet more stringent emission regulations (such as controlling NOₓ and NH₃ emissions at the same time);\u003cbr\u003eImprove the overall efficiency of the system and avoid ammonia waste.\u003c\/p\u003e\n\u003cp\u003e4. In what scenarios is SCR+ASC suitable?\u003cbr\u003eIn areas with strict emission regulations (such as National VI and above);\u003cbr\u003eApplication scenarios with extremely high requirements for exhaust emissions, such as urban buses, logistics transport vehicles, etc.\u003c\/p\u003e\n\u003cp\u003e5. What are the precautions for the maintenance of both?\u003cbr\u003eSCR: Regularly check whether the urea injection system is blocked and monitor the activity of the catalyst (to avoid high-temperature sintering or poisoning).\u003cbr\u003eSCR+ASC: In addition to the maintenance of SCR, it is necessary to pay extra attention to whether the ASC module is blocked or the catalyst fails, and regularly clean up impurities such as carbon deposits.\u003c\/p\u003e\n\u003cp\u003e6. How is the emission effect compared?\u003c\/p\u003e\n\u003cp\u003eSCR: Only control NOₓ emissions to within the limit;\u003c\/p\u003e\n\u003cp\u003eSCR+ASC: While controlling NOₓ, NH₃ emissions are also reduced to an extremely low level, which is more environmentally friendly.\u003c\/p\u003e\n\u003cp\u003e7. How to solve the ammonia slip problem in SCR?\u003c\/p\u003e\n\u003cp\u003eThrough the SCR+ASC system, the catalyst of the ASC module (such as precious metal Pt\/Pd) is used to catalytically oxidize the escaped ammonia into harmless nitrogen and water.\u003c\/p\u003e\n\u003cp\u003e8. What factors affect the life of the catalyst?\u003c\/p\u003e\n\u003cp\u003eTemperature: Too high a temperature (such as \u0026amp;gt; 600℃) may cause the catalyst to sinter and deactivate;\u003c\/p\u003e\n\u003cp\u003eUrea quality: Impurities in inferior urea (such as biuret) will contaminate the catalyst;\u003c\/p\u003e\n\u003cp\u003eSulfur content: Sulfur in fuel or urea will poison the catalyst and shorten its life. Generally, the life of SCR catalyst is 2-5 years, and SCR+ASC requires comprehensive maintenance to extend the overall life.\u003c\/p\u003e\n\u003cstyle\u003e\n        table {\n            border-collapse: collapse;\n            width: 600px;

SCR is the core of NOx purification, but the amount of urea injection needs to be precisely controlled to avoid insufficient NH₃ (low NOx conversion rate) or excessive NH₃ (NH₃ escape).\u003c\/p\u003e\n\u003cp\u003e2. ASC is a supplement to SCR to solve the problem of NH₃ escape, especially suitable for scenarios where regulations have strict restrictions on NH₃ emissions (such as National VI b stage).\u003c\/p\u003e\n\u003cp\u003e3. Collaborative design: SCR and ASC need to match exhaust flow rate and temperature window (ASC operating temperature is usually 200-450°C) to ensure overall efficiency.\u003c\/p\u003e\n\u003cp\u003eFAQ on SCR and SCR+ASC catalytic conversion reaction of diesel vehicles\u003c\/p\u003e\n\u003cp\u003e1. What are SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR (Selective Catalytic Reduction): By injecting urea solution into the exhaust gas, urea decomposes to produce ammonia (NH₃). Under the action of the catalyst, ammonia selectively reduces nitrogen oxides (NOₓ) to nitrogen (N₂) and water (H₂O), mainly used to reduce NOₓ emissions in diesel vehicle exhaust.\u003c\/p\u003e\n\u003cp\u003eSCR+ASC (Ammonia Escape Catalytic Converter): Add an ASC module on the basis of SCR. ASC can catalytically oxidize excess ammonia (ammonia escape) after the SCR reaction into nitrogen and water, further reducing ammonia pollution to the environment.\u003c\/p\u003e\n\u003cp\u003e2. What is the core difference between SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR only reduces NOₓ, while SCR+ASC can not only reduce NOₓ, but also eliminate ammonia that may escape from the SCR system, meeting stricter NOₓ and NH₃ emission limits.\u003c\/p\u003e\n\u003cp\u003e3. What are the advantages of SCR+ASC?\u003cbr\u003eReduce the pollution of ammonia escape to the atmosphere (such as avoiding the formation of ammonium salt particles);\u003cbr\u003eMeet more stringent emission regulations (such as controlling NOₓ and NH₃ emissions at the same time);\u003cbr\u003eImprove the overall efficiency of the system and avoid ammonia waste.\u003c\/p\u003e\n\u003cp\u003e4. In what scenarios is SCR+ASC suitable?\u003cbr\u003eIn areas with strict emission regulations (such as National VI and above);\u003cbr\u003eApplication scenarios with extremely high requirements for exhaust emissions, such as urban buses, logistics transport vehicles, etc.\u003c\/p\u003e\n\u003cp\u003e5. What are the precautions for the maintenance of both?\u003cbr\u003eSCR: Regularly check whether the urea injection system is blocked and monitor the activity of the catalyst (to avoid high-temperature sintering or poisoning).\u003cbr\u003eSCR+ASC: In addition to the maintenance of SCR, it is necessary to pay extra attention to whether the ASC module is blocked or the catalyst fails, and regularly clean up impurities such as carbon deposits.\u003c\/p\u003e\n\u003cp\u003e6. How is the emission effect compared?\u003c\/p\u003e\n\u003cp\u003eSCR: Only control NOₓ emissions to within the limit;\u003c\/p\u003e\n\u003cp\u003eSCR+ASC: While controlling NOₓ, NH₃ emissions are also reduced to an extremely low level, which is more environmentally friendly.\u003c\/p\u003e\n\u003cp\u003e7. How to solve the ammonia slip problem in SCR?\u003c\/p\u003e\n\u003cp\u003eThrough the SCR+ASC system, the catalyst of the ASC module (such as precious metal Pt\/Pd) is used to catalytically oxidize the escaped ammonia into harmless nitrogen and water.\u003c\/p\u003e\n\u003cp\u003e8. What factors affect the life of the catalyst?\u003c\/p\u003e\n\u003cp\u003eTemperature: Too high a temperature (such as \u0026amp;gt; 600℃) may cause the catalyst to sinter and deactivate;\u003c\/p\u003e\n\u003cp\u003eUrea quality: Impurities in inferior urea (such as biuret) will contaminate the catalyst;\u003c\/p\u003e\n\u003cp\u003eSulfur content: Sulfur in fuel or urea will poison the catalyst and shorten its life. Generally, the life of SCR catalyst is 2-5 years, and SCR+ASC requires comprehensive maintenance to extend the overall life.\u003c\/p\u003e\n\u003cstyle\u003e\n        table {\n            border-collapse: collapse;\n            width: 600px;

SCR is the core of NOx purification, but the amount of urea injection needs to be precisely controlled to avoid insufficient NH₃ (low NOx conversion rate) or excessive NH₃ (NH₃ escape).\u003c\/p\u003e\n\u003cp\u003e2. ASC is a supplement to SCR to solve the problem of NH₃ escape, especially suitable for scenarios where regulations have strict restrictions on NH₃ emissions (such as National VI b stage).\u003c\/p\u003e\n\u003cp\u003e3. Collaborative design: SCR and ASC need to match exhaust flow rate and temperature window (ASC operating temperature is usually 200-450°C) to ensure overall efficiency.\u003c\/p\u003e\n\u003cp\u003eFAQ on SCR and SCR+ASC catalytic conversion reaction of diesel vehicles\u003c\/p\u003e\n\u003cp\u003e1. What are SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR (Selective Catalytic Reduction): By injecting urea solution into the exhaust gas, urea decomposes to produce ammonia (NH₃). Under the action of the catalyst, ammonia selectively reduces nitrogen oxides (NOₓ) to nitrogen (N₂) and water (H₂O), mainly used to reduce NOₓ emissions in diesel vehicle exhaust.\u003c\/p\u003e\n\u003cp\u003eSCR+ASC (Ammonia Escape Catalytic Converter): Add an ASC module on the basis of SCR. ASC can catalytically oxidize excess ammonia (ammonia escape) after the SCR reaction into nitrogen and water, further reducing ammonia pollution to the environment.\u003c\/p\u003e\n\u003cp\u003e2. What is the core difference between SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR only reduces NOₓ, while SCR+ASC can not only reduce NOₓ, but also eliminate ammonia that may escape from the SCR system, meeting stricter NOₓ and NH₃ emission limits.\u003c\/p\u003e\n\u003cp\u003e3. What are the advantages of SCR+ASC?\u003cbr\u003eReduce the pollution of ammonia escape to the atmosphere (such as avoiding the formation of ammonium salt particles);\u003cbr\u003eMeet more stringent emission regulations (such as controlling NOₓ and NH₃ emissions at the same time);\u003cbr\u003eImprove the overall efficiency of the system and avoid ammonia waste.\u003c\/p\u003e\n\u003cp\u003e4. In what scenarios is SCR+ASC suitable?\u003cbr\u003eIn areas with strict emission regulations (such as National VI and above);\u003cbr\u003eApplication scenarios with extremely high requirements for exhaust emissions, such as urban buses, logistics transport vehicles, etc.\u003c\/p\u003e\n\u003cp\u003e5. What are the precautions for the maintenance of both?\u003cbr\u003eSCR: Regularly check whether the urea injection system is blocked and monitor the activity of the catalyst (to avoid high-temperature sintering or poisoning).\u003cbr\u003eSCR+ASC: In addition to the maintenance of SCR, it is necessary to pay extra attention to whether the ASC module is blocked or the catalyst fails, and regularly clean up impurities such as carbon deposits.\u003c\/p\u003e\n\u003cp\u003e6. How is the emission effect compared?\u003c\/p\u003e\n\u003cp\u003eSCR: Only control NOₓ emissions to within the limit;\u003c\/p\u003e\n\u003cp\u003eSCR+ASC: While controlling NOₓ, NH₃ emissions are also reduced to an extremely low level, which is more environmentally friendly.\u003c\/p\u003e\n\u003cp\u003e7. How to solve the ammonia slip problem in SCR?\u003c\/p\u003e\n\u003cp\u003eThrough the SCR+ASC system, the catalyst of the ASC module (such as precious metal Pt\/Pd) is used to catalytically oxidize the escaped ammonia into harmless nitrogen and water.\u003c\/p\u003e\n\u003cp\u003e8. What factors affect the life of the catalyst?\u003c\/p\u003e\n\u003cp\u003eTemperature: Too high a temperature (such as \u0026amp;gt; 600℃) may cause the catalyst to sinter and deactivate;\u003c\/p\u003e\n\u003cp\u003eUrea quality: Impurities in inferior urea (such as biuret) will contaminate the catalyst;\u003c\/p\u003e\n\u003cp\u003eSulfur content: Sulfur in fuel or urea will poison the catalyst and shorten its life. Generally, the life of SCR catalyst is 2-5 years, and SCR+ASC requires comprehensive maintenance to extend the overall life.\u003c\/p\u003e\n\u003cstyle\u003e\n        table {\n            border-collapse: collapse;\n            width: 600px;

ASC can catalytically oxidize excess ammonia (ammonia escape) after the SCR reaction into nitrogen and water, further reducing ammonia pollution to the environment.\u003c\/p\u003e\n\u003cp\u003e2. What is the core difference between SCR and SCR+ASC?\u003c\/p\u003e\n\u003cp\u003eSCR only reduces NOₓ, while SCR+ASC can not only reduce NOₓ, but also eliminate ammonia that may escape from the SCR system, meeting stricter NOₓ and NH₃ emission limits.\u003c\/p\u003e\n\u003cp\u003e3. What are the advantages of SCR+ASC?\u003cbr\u003eReduce the pollution of ammonia escape to the atmosphere (such as avoiding the formation of ammonium salt particles);\u003cbr\u003eMeet more stringent emission regulations (such as controlling NOₓ and NH₃ emissions at the same time);\u003cbr\u003eImprove the overall efficiency of the system and avoid ammonia waste.\u003c\/p\u003e\n\u003cp\u003e4. In what scenarios is SCR+ASC suitable?\u003cbr\u003eIn areas with strict emission regulations (such as National VI and above);\u003cbr\u003eApplication scenarios with extremely high requirements for exhaust emissions, such as urban buses, logistics transport vehicles, etc.\u003c\/p\u003e\n\u003cp\u003e5. What are the precautions for the maintenance of both?\u003cbr\u003eSCR: Regularly check whether the urea injection system is blocked and monitor the activity of the catalyst (to avoid high-temperature sintering or poisoning).\u003cbr\u003eSCR+ASC: In addition to the maintenance of SCR, it is necessary to pay extra attention to whether the ASC module is blocked or the catalyst fails, and regularly clean up impurities such as carbon deposits.\u003c\/p\u003e\n\u003cp\u003e6. How is the emission effect compared?\u003c\/p\u003e\n\u003cp\u003eSCR: Only control NOₓ emissions to within the limit;\u003c\/p\u003e\n\u003cp\u003eSCR+ASC: While controlling NOₓ, NH₃ emissions are also reduced to an extremely low level, which is more environmentally friendly.\u003c\/p\u003e\n\u003cp\u003e7. How to solve the ammonia slip problem in SCR?\u003c\/p\u003e\n\u003cp\u003eThrough the SCR+ASC system, the catalyst of the ASC module (such as precious metal Pt\/Pd) is used to catalytically oxidize the escaped ammonia into harmless nitrogen and water.\u003c\/p\u003e\n\u003cp\u003e8. What factors affect the life of the catalyst?\u003c\/p\u003e\n\u003cp\u003eTemperature: Too high a temperature (such as \u0026amp;gt; 600℃) may cause the catalyst to sinter and deactivate;\u003c\/p\u003e\n\u003cp\u003eUrea quality: Impurities in inferior urea (such as biuret) will contaminate the catalyst;\u003c\/p\u003e\n\u003cp\u003eSulfur content: Sulfur in fuel or urea will poison the catalyst and shorten its life. Generally, the life of SCR catalyst is 2-5 years, and SCR+ASC requires comprehensive maintenance to extend the overall life.\u003c\/p\u003e\n\u003cstyle\u003e\n        table {\n            border-collapse: collapse;\n            width: 600px;
