Title (EN) SMALL ENGINE PALLADIUM CATALYST ARTICLE AND METHOD OF MAKING
(FR) ARTICLE CATALYTIQUE EN PALLADIUM POUR PETITS MOTEURS ET PROCÉDÉ DE FABRICATION ASSOCIÉ
Abstract:
(EN) Catalyst articles comprising substantially only a palladium precious metal component and related methods of preparation and use are disclosed. Disclosed is a catalyst article comprising a first layer formed on a carrier substrate, wherein the first layer comprises a refractory metal oxide and has a surface that is substantially uniform; and a second layer formed on the first layer, wherein the second layer comprises i) an oxygen storage component that is about 50-90% by weight of the second layer and ii) a palladium component in an amount of about 10-150 g/ft3 of palladium, wherein the palladium component is substantially the only platinum group metal component. One or more improved properties are exhibited by the catalyst article.
(FR) La présente invention concerne des articles catalytiques ne comprenant pratiquement qu'un composant en métal précieux, le palladium, et des procédés associés de préparation et d'utilisation. L'invention concerne un article catalytique comprenant une première couche, qui est formée sur un substrat porteur, comprend un oxyde métallique réfractaire et a une surface qui est pratiquement uniforme ; et une deuxième couche, qui est formée sur la première couche et comprend i) un composant de stockage d'oxygène qui représente environ 50 à 90 % du poids de la deuxième couche et ii) un composant palladium dans une quantité d'environ 10-150 g/ft3 de palladium, le composant palladium étant pratiquement le seul composant métallique du groupe platine. L'article catalytique présente une ou plusieurs propriétés améliorées.
