(DE) KATALYTISCH AKTIVES PARTIKELFILTER
(EN) CATALYTICALLY ACTIVE PARTICULATE FILTER
(FR) FILTRE À PARTICULES À ACTIVITÉ CATALYTIQUE
Abstract
(DE)
Die vorliegende Erfindung betrifft ein Partikelfilter, das ein Wandflussfilter der Länge L und zwei katalytisch aktive Beschichtungen Y und Z umfasst, wobei das Wandflussfilter Kanäle E und A umfasst, die sich parallel zwischen einem ersten und einem zweiten Ende des Wandflussfilters erstrecken und die durch poröse Wände getrennt sind, die Oberflächen OE bzw. OA bilden und wobei die Kanäle E am zweiten Ende und die Kanäle A am ersten Ende verschlossen sind, und wobei die Beschichtungen Y und Z gleiche Sauerstoffspeicherkomponenten und gleiche Trägermaterialien für Edelmetalle umfassen, dadurch gekennzeichnet, dass sich Beschichtung Y in den Kanälen E auf den Oberflächen OE und Beschichtung Z in den Kanälen A auf den Oberflächen OA befindet.
(EN)
The invention relates to a particulate filter which comprises a wall flow filter of length L and two catalytically active coatings Y and Z, wherein the wall flow filter comprises channels E and A that extend in parallel between a first and a second end of the wall flow filter and are separated by porous walls which form surfaces OE and OA, respectively, and wherein the channels E are closed at the second end and the channels A are closed at the first end, and the coatings Y and Z have the same oxygen storage components and the same carrier materials for noble metals. The invention is characterised in that the coating Y is located in the channels E on the surfaces OE and the coating Z is located in the channels A on the surfaces OA.
(FR)
La présente invention concerne un filtre à particules qui comporte un filtre à effet wall-flow de longueur L et deux revêtements à activité catalytique Y et Z, le filtre à effet wall-flow comportant des conduits E et A qui s’étendent parallèlement entre une première et une seconde extrémité du filtre à effet wall-flow et qui sont séparés par des parois poreuses qui forment respectivement les surfaces OE et OA, les conduits E étant fermés à la seconde extrémité et les conduits A étant fermés à la première extrémité, les revêtements Y et Z comportent les mêmes composants accumulateurs d’oxygène et les mêmes supports pour métaux précieux. Ce filtre à particules est caractérisé en ce que le revêtement Y se trouve dans les conduits E sur les surfaces OE et le revêtement Z se trouve dans les conduits A sur les surfaces OA.
