Abstract

La présente invention concerne un catalyseur de piège à hydrocarbures destinés à commander des émissions d'hydrocarbures HC provenant de moteurs à combustion interne. Le catalyseur comprend un tamis moléculaire comprenant du potassium et de l'argent, le tamis moléculaire ayant un diamètre de pore minimal d'au moins 4,5 Å et un diamètre de pore maximal inférieur à 7,5 Å et un rapport silice/alumine (SAR) dans la plage de 9,0 à 90,0, la quantité de potassium dans le tamis moléculaire étant dans la plage de 0,1 % à 4,0 % en poids, et la quantité d'argent dans le tamis moléculaire étant dans la plage de 0,2 % à 10,0 % en poids, dans chaque cas sur la base du poids total du catalyseur de piège à hydrocarbures. La présente invention concerne également un procédé de préparation du catalyseur de piège à hydrocarbures. La présente invention concerne en outre un article catalytique de piège à hydrocarbures et son utilisation en tant que piège à hydrocarbures à démarrage à froid.
