| description | The invention relates to a catalyst for lowering the amount of NO x in the lean exhaust gas from lean burn engines, comprising active aluminum oxide, magnesium oxide and at least one noble metal of the platinum group of the periodic table of the elements, as well as at least one nitrogen oxide storage material. The catalyst is characterized in that the magnesium oxide forms a homogeneous mixed oxide with aluminum oxide and is present in a concentration of about 1 to about 40 wt- %, based on the total weight of the mixed oxide.
L'invention concerne un catalyseur pour la réduction de la quantité de NO x dans le gaz d'échappement de moteurs à mélange pauvre, comprenant l'oxyde d'aluminium actif, l'oxyde de magnésium et au moins un métal noble de la famille de platine dans la table périodique des éléments, ainsi qu'au moins un matériau de stockage d'oxyde d'azote. Le catalyseur est caractérisé en ce que l'oxyde de magnésium forme un oxyde mixte homogène avec de l'oxyde d'aluminium et est présent dans une concentration d'environ 1 à environ 40 % en poids, en fonction du poids total de l'oxyde mixte. |
