Abstract[English]
The invention relates to a catalyst comprising a substrate with a cross-sectional shape wherein the internal angle is more than 90 degrees. The substrate is coated with an ammonia slip catalyst (ASC) layer and a second layer positioned on the ASC layer, wherein the ASC layer comprises a platinum group metal (PGM) and a support, and the second layer comprises a SCR catalyst. The relative layer thickness deviation of the second layer with respect to the mean layer thickness of the second layer is less than 60%.[French]
L'invention concerne un catalyseur comprenant un substrat ayant une forme de section transversale, l'angle interne étant supérieur à 90 degrés. Le substrat est revêtu d'une couche de catalyseur d'oxydation d'ammoniac (ASC) et d'une seconde couche positionnée sur la couche ASC, la couche ASC comprenant un métal du groupe du platine (PGM) et un support, et la seconde couche comprenant un catalyseur SCR. L'écart d'épaisseur de couche relative de la seconde couche par rapport à l'épaisseur de couche moyenne de la seconde couche est inférieur à 60%.
