Title (EN) MULTILAYERED THREE-WAY CONVERSION CATALYST COMPOSITIONS
(FR) COMPOSITIONS DE CATALYSEUR DE CONVERSION MULTICOUCHES À TROIS VOIES
Abstract: front page image
(EN)A multilayered, three-way conversion catalyst having the capability of simultaneously catalyzing the oxidation of hydrocarbons and carbon monoxide and the reduction of nitrogen oxides is disclosed. Provided is a catalytic material of at least four layers in conjunction with a carrier, where each of the layers includes a support, at least three layers comprise a precious metal component, and at least one layer comprises an oxygen storage component (OSC). The catalytic material can further comprise a fifth layer, where at least four layers comprise a precious metal component, at least one layer comprises an oxygen storage component, and at least one layer is substantially free of an oxygen storage component.
(FR)La présente invention concerne un catalyseur de conversion multicouches à trois voies ayant la capacité de catalyser simultanément l'oxydation d'hydrocarbures et du monoxyde de carbone et la réduction des oxydes d'azote. Un matériau catalytique d'au moins quatre couches conjointement avec un support est fourni, dans lequel chacune des couches comporte un support, au moins trois couches comprennent un composant métallique précieux, et au moins une couche comprend un composant de stockage d'oxygène (CSO). Le matériau catalytique peut comprendre en outre une cinquième couche, dans laquelle au moins quatre couches comprennent un composant métallique précieux, au moins une couche comprend un composant de stockage d'oxygène, et au moins une couche est sensiblement exempte d'un composant de stockage d'oxygène.
