Title
(EN) HYDROCARBON TRAP CATALYST
(FR) CATALYSEUR DE PIÉGEAGE À HYDROCARBURES
Abstract
(EN) The present invention relates to a catalyst comprising a carrier substrate of the length L extending between substrate ends a and b and two washcoat zones A and B, wherein washcoat zone A comprises a redox active base metal and palladium supported on a zeolite and/or refractory oxide support and extends starting from substrate end a over a part of the length L, and washcoat zone B comprises the same components as washcoat A and an additional amount of palladium and extends from substrate end b over a part of the length L, wherein L = LA + LB, wherein LA is the length of washcoat zone A and LB is the length of substrate length B.
(FR) La présente invention concerne un catalyseur comprenant un substrat de support de longueur L s'étendant entre les extrémités a et b du substrat et deux zones de revêtement catalytique A et B, la zone de revêtement catalytique A comprenant un métal de base à activité redox et du palladium sur un support de zéolite et/ou d'oxyde réfractaire, et s'étendant à partir de l'extrémité a du substrat sur une partie de la longueur L, et la zone de revêtement catalytique B comprenant les mêmes composants que la zone de revêtement catalytique A auxquels s'ajoute du palladium, et s'étendant à partir de l'extrémité b du substrat sur une partie de la longueur L, où L = LA + LB, LA étant la longueur de la zone de revêtement catalytique A et LB étant la longueur B du substrat.
