Abstract[English]
O in the selective catalytic reduction (SCR) of NOX, in a gas mixture, comprising contacting the gas mixture with a source of ammonia, over a selective catalytic reduction catalyst comprising a zeolite comprising copper (Cu), cerium (Ce) and yttrium (Y), wherein the Cu to Ce to Y weight percentage ratio, based on the weight of the zeolite, is in the range of 1.0:1.0:0.5 to 5.0:5.0:3.0. There is also provided an SCR catalyst, use of said SCR catalyst and an associated exhaust system.[French]
O dans la réduction catalytique sélective (SCR) de NOX, dans un mélange gazeux, comprenant la mise en contact du mélange gazeux avec une source d'ammoniac, sur un catalyseur de réduction catalytique sélective comprenant une zéolite comprenant du cuivre (Cu), du cérium (Ce) et de l'yttrium (Y), le rapport en pourcentage en poids de Cu à Y, sur la base du poids de la zéolite, étant dans la plage de 1,0:1,0:0,5 à 5,0:5,0:3,0. L'invention concerne également un catalyseur SCR, l'utilisation dudit catalyseur SCR et un système d'échappement associé.
