Title (EN) CATALYST FOR REDUCTION OF NITROGEN OXIDES
(FR) CATALYSEUR DE RÉDUCTION DES OXYDES D’AZOTE
(DE) KATALYSATOR ZUR REDUKTION VON STICKOXIDEN
Abstract:
(EN) The present invention relates to a catalyst comprising a support body A having a length LA designed as a flow substrate, a support body B of length LB designed as a wall-flow filter, and material zones A1, A2, B1 and B2, wherein the support body A comprises material zones A1 and A2 and the support body B comprises material zones B1 and B2, wherein material zone A1 contains a cerium oxide, an alkaline earth metal compound and/or an alkali metal compound, and also platinum and/or palladium, and material zone A2 contains cerium oxide, and also platinum and/or palladium, and is free of alkali metal and alkaline earth metal compounds, material zone B1 contains palladium supported on cerium oxide, and material zone B2 contains platinum supported on a support material.
(FR) La présente invention concerne un catalyseur qui comprend un élément de support (A) d’une longueur LA réalisé sous la forme d’un substrat d’écoulement, un élément de support (B) de longueur LB réalisé sous la forme d’un filtre à parois filtrantes, et des zones de matière (A1, A2, B1 et B2), l’élément de support (A) comprenant les zones de matière (A1 et A2) et l’élément de support (B) comprenant les zones de matière (B1 et B2). La zone de matière (A1) contient de l’oxyde de cérium, un composé alcalino-terreux et/ou un composé alcalin ainsi que du platine et/ou du palladium et la zone de matière (A2) contient de l’oxyde de cérium ainsi que du platine et/ou du palladium et ne contient pas de composé alcalino-terreux ou alcalin, et la zone de matière (B1) contient du palladium porté sur de l’oxyde de cérium et la zone de matière (B2), du platine porté sur un matériau de support.
(DE) Die vorliegende Erfindung betrifft einen Katalysator der einen Tragkörper A mit einer Länge LA, der als Durchflusssubstrat ausgeführt ist, einen Tragkörper B der Länge LB, der als Wandflussfilter ausgeführt ist, und Materialzonen A1, A2, B1 und B2 umfasst, wobei der Tragkörper A die Materialzonen A1 und A2 und der Tragkörper B die Materialzonen B1 und B2umfasst, wobei Materialzone A1 Ceroxid, eine Erdalkaliverbindung und/oder eine Alkaliverbindung, sowie Platin und/oder Palladium enthält und Materialzone A2 Ceroxid, sowie Platin und/oder Palladium enthält und frei von Erdalkali-und Alkaliverbindungen ist, Materialzone B1 Palladium geträgert auf Ceroxid und Materialzone B2 Platin geträgert auf einem Trägermaterialenthält.
