Title
(EN) CATALYST COMPOSITIONS
(FR) COMPOSITIONS DE CATALYSEUR
Abstract
(EN)
A catalyst composition containing a molecular sieve containing palladium and ceria is provided, which exhibits outstanding sulfur resistance. The catalyst composition is suitable for treating an exhaust gas stream including hydrocarbons and/or carbon monoxide and/or Nox.
(FR)
L'invention concerne une composition de catalyseur contenant un tamis moléculaire contenant du palladium et de l'oxyde de cérium, qui présente une remarquable résistance au soufre. La composition de catalyseur est appropriée pour traiter un flux de gaz d'échappement comprenant des hydrocarbures et/ou du monoxyde de carbone et/ou des Nox.
