Title (EN) PROCESS OF TREATING DIESEL EXHAUST GAS USING CERIA-ZIRCONIA-MIXED OXIDE PARTICLES PRODUCED BY PYROLYSIS
(FR) PROCÉDÉ DE TRAITEMENT DE GAZ D'ÉCHAPPEMENT DIESEL UTILISANT DES PARTICULES D'OXYDE MIXTE D'OXYDE DE CÉRIUM ET D'OXYDE DE ZIRCONIUM PRODUITES PAR PYROLYSE
Abstract:
(EN) The present invention relates to a process for the treatment of diesel exhaust gas comprising (a) providing a diesel exhaust gas stream; (b) contacting the diesel exhaust gas stream provided in (a) with a diesel oxidation catalyst; wherein the diesel oxidation catalyst comprises ceria-zirconia mixed oxide particles, wherein the average particle size d50 of the ceria-zirconia mixed oxide particles, preferably of the ceria-zirconia mixed oxide particles as synthesized, is comprised in the range of from 5 nm to 40 μm.
(FR) La présente invention concerne un procédé pour le traitement de gaz d'échappement diesel comprenant (a) la fourniture d'un flux de gaz d'échappement diesel; (b) la mise en contact du flux de gaz d'échappement diesel fourni en (a) avec un catalyseur d'oxydation diesel; dans lequel le catalyseur d'oxydation diesel comprend des particules d'oxyde mixte d'oxyde de cérium et d'oxyde de zirconium, dans lequel la taille moyenne de particule d50 des particules d'oxyde mixte d'oxyde de cérium et d'oxyde de zirconium, de préférence des particules d'oxyde mixte d'oxyde de cérium et d'oxyde de zirconium comme synthétisé, est comprise dans la plage allant de 5 nm à 40 µm.
