Abstract
(EN)
Catalytic articles, methods and emissions treatment systems for treating an engine exhaust gas stream containing NOx and particulate matter are disclosed and include a particulate filter comprising a first SCR catalyst for NOx conversion disposed downstream of the injector. The particulate filter is a partial filter with a particle filtration efficiency between about 30% and 60% and an SCR catalyst loading in the range of 0.1 g/in3 - 3.5 g/in3.

L'invention porte sur des articles catalytiques, sur des procédés et sur des systèmes de traitement des émissions, destinés à traiter un courant de gaz d'échappement d'un moteur, contenant du NOx et des matières particulaires, qui comprennent un filtre à particules, comprenant un premier catalyseur SCR pour conversion des NOx, disposé en aval de l'injecteur. Le filtre à particules est un filtre partiel, avec un rendement de filtration des particules compris entre environ 30 % et 60 %, et une charge de catalyseur SCR comprise entre 0,1 et 3,5 g/pouce3.
