Title (EN) DIESEL OXIDATION CATALYST WITH LAYER STRUCTURE FOR IMPROVED HYDROCARBON CONVERSION
(FR) CATALYSEUR D'OXYDATION DIESEL À STRUCTURE EN COUCHE POUR UNE MEILLEURE CONVERSION DES HYDROCARBURES
Abstract:
(EN) Provided is a diesel oxidation catalyst for the treatment of exhaust gas emissions from a diesel engine and a method for treating a diesel exhaust gas stream, the method comprising providing a diesel oxidation catalyst and contacting said diesel exhaust gas stream with said diesel oxidation catalyst for the treatment of exhaust gas emissions. More particularly, the present invention is directed to a catalyst structure comprising three distinct layers; in which layer comprises a precious metal component such as palladium is located between two hydrocarbon storage layers comprising a molecular sieve such as a zeolite.
(FR) La présente invention concerne, d'une part un catalyseur d'oxydation diesel destiné au traitement des émissions de gaz d'échappement provenant d'un moteur diesel, et d'autre part un procédé destiné au traitement d'un courant de gaz d'échappement diesel. Le procédé consiste à prendre un catalyseur d'oxydation diesel, et à mettre ce courant de gaz d'échappement diesel en contact avec le catalyseur d'oxydation diesel pour le traitement des émissions de gaz d'échappement. L'invention concerne plus particulièrement une structure de catalyseur comprenant trois couches distinctes. En l'occurrence, une couche comprenant un composant à base de métal précieux tel que le palladium est prise en sandwich entre deux couches de stockage d'hydrocarbure comprenant un tamis moléculaire tel qu'une zéolite.
