Abstract[English]
This invention relates to selective catalytic reduction (SCR) catalysts with improved tolerance towards sulfation. The invention further extends to the use of such catalysts in emission treatment systems. More specifically, the invention is related to a catalyst for treating an exhaust gas comprising NOx, said catalyst comprising a metal loaded zeolite and a silica-alumina or titania-alumina binder.[French]
La présente invention concerne des catalyseurs de réduction catalytique sélective (RCS) présentant une tolérance améliorée vis-à-vis de la sulfatation. L'invention concerne en outre l'utilisation de tels catalyseurs dans des systèmes de traitement d'émission. Plus précisément, l'invention concerne un catalyseur de traitement d'un gaz d'échappement comprenant des NOx, ledit catalyseur comprenant une zéolithe chargée en métal et un liant silice-alumine ou dioxyde de titane-alumine.
