Abstract

Ciertos artículos, sistemas y métodos de reducción catalítica selectiva (SCR) proporcionan una alta conversión de NOx y, al mismo tiempo, una baja formación de N2O. Los artículos, sistemas y métodos son adecuados, por ejemplo, para el tratamiento de gases de escape de motores diésel. Ciertos artículos tienen recubrimientos divididos en zonas que contienen tamices moleculares que contienen cobre dispuestos sobre los mismos, donde, por ejemplo, una concentración de cobre catalítico en una zona aguas arriba es más baja que la concentración de cobre catalítico en una zona aguas abajo.
