Title (EN) PALLADIUM/ZEOLITE-BASED PASSIVE NITROGEN OXIDE ADSORBER CATALYST FOR PURIFYING EXHAUST GAS
(FR) CATALYSEUR ADSORBANT PASSIF D’OXYDE D'AZOTE À BASE DE PALLADIUM-ZÉOLITE POUR LA PURIFICATION DE GAZ D'ÉCHAPPEMENT
(DE) PALLADIUM-ZEOLITH-BASIERTER PASSIVER STICKOXID-ADSORBER-KATALYSATOR ZUR ABGASREINIGUNG
Abstract:
(EN) The invention relates to a catalyst which comprises a carrier substrate, palladium, and a zeolite, the largest channels of which are formed by 10 tetradrically coordinated atoms; to the use of said catalyst as a passive nitrogen oxide adsorber, an exhaust gas system which contains said catalyst and an SCR catalyst, and to a method for purifying the exhaust gas of motor vehicles using said exhaust gas system.
(FR) L’invention concerne un catalyseur qui comprend un substrat de support, du palladium et une zéolite dont les canaux de taille supérieure sont formés par 10 atomes coordonnés de façon tétraédrique; l'utilisation de ce catalyseur en tant qu’adsorbant passif d’oxyde d’azote ; un système d'échappement contenant ce dernier et un catalyseur SCR ; et un procédé de purification de gaz d'échappement de véhicules à moteur à l’aide de ce système d'échappement.
(DE) Die vorliegende Erfindung betrifft einen Katalysator, der ein Trägersubstrat, Palladium und einen Zeolithen, dessen größte Kanäle von 10 tetraedrisch koordinierten Atomen gebildet werden, umfasst; die Verwendung dieses Katalysators als Passiver Stickoxid-Adsorber; ein diesen und einen SCR-Katalysator enthaltendes Abgassystem, sowie ein Verfahren zur Abgasreinigung von Kraftfahrzeugen mithilfe dieses Abgassystems.
