SCR+ASC
1. SCR (Selektive Katalytische Reduktion)
1. Funktion
Kernziel: Stickoxide (NOx) im Abgas in unschädlichen Stickstoff (N₂) und Wasser (H₂O) umwandeln.
Anwendbare Szenarien: Abgasbehandlung von Dieselfahrzeugen, um die NOx-Grenzwertanforderungen der nationalen Emissionsvorschriften VI/Euro VI zu erfüllen.
Wichtige Eingabe: Als Reduktionsmittel muss eine wässrige Harnstofflösung (AdBlue, enthält 32,5 % Harnstoff) hinzugefügt werden.
2. Funktionsprinzip
Harnstoffeinspritzung: Harnstofflösung wird in das Auspuffrohr gesprüht und bei hoher Temperatur hydrolysiert, um Ammoniak (NH₃) zu erzeugen.
Katalytische Reduktion: NH₃ durchläuft eine selektive Reduktionsreaktion mit NOx auf der Oberfläche des SCR-Katalysators, wobei N₂ und H₂O entstehen.
Katalysatortyp: Auf Vanadiumbasis (V₂O₅-WO₃/TiO₂) oder Zeolith-Molekularsieb (wie Cu-ZSM-5).
2. SCR+ASC (SCR + Ammoniak-Entweichungskatalysator)
1. Funktion
Kernziel: Auf Basis von SCR noch mehr nicht umgesetztes Restammoniak (NH₃-Austritt) eliminieren, um Sekundärverschmutzung zu vermeiden.
Zusatzfunktionen:
Oxidation von restlichem NH₃ zu N₂ und H₂O;
Einige ASCs können sowohl CO (Kohlenmonoxid) als auch HC (Kohlenwasserstoffe) oxidieren.
2. Funktionsprinzip
Standort: ASC befindet sich stromabwärts des SCR-Katalysators.
Katalytische Oxidation: Verwenden Sie Edelmetallkatalysatoren (wie Pt/Pd), um entwichenes NH₃ selektiv zu N₂ statt zu NOx zu oxidieren.
Schutz vor Überoxidation: Die Reaktionsbedingungen müssen präzise kontrolliert werden, um eine übermäßige Oxidation von NH₃ zur Entstehung von NOx zu vermeiden.
