Title (EN) DIESEL OXIDATION CATALYST COMPOSITE WITH LAYER STRUCTURE FOR CARBON MONOXIDE AND HYDROCARBON CONVERSION
(FR) COMPOSITE CATALYSEUR D'OXYDATION DIESEL À STRUCTURE EN COUCHES POUR LA CONVERSION DU MONOXYDE DE CARBONE ET DES HYDROCARBURES
Abstract:
(EN) Provided is a catalyst composition, in particular a diesel oxidation catalyst, for the treatment of exhaust gas emissions, such as the oxidation of unburned hydrocarbons (HC), and carbon monoxide (CO). More particularly, the present invention is directed to a catalyst structure comprising at least two, specifically three distinct layers, at least one of which contains an oxygen storage component (OSC) that is present in a layer separate from the majority of the platinum group metal (PGM) components, such as palladium and platinum.
(FR) La présente invention concerne une composition de catalyseur, en particulier un catalyseur d'oxydation diesel, destiné au traitement des émissions de gaz d'échappement, et notamment à l'oxydation des hydrocarbures non brûlés (HC), et du monoxyde de carbone (CO). L'invention concerne plus particulièrement une structure de catalyseur comprenant au moins deux couches distinctes, et en particulier trois couches distinctes, dont l'une au moins contient un composant stockant l'oxygène ou "OSC" (Oxygen Storage Component) qui est présent dans une couche séparée de la majorité des composants métalliques du groupe du platine ou "PGM" (Platinum Group Metal) tels que le palladium et le platine.
