(EN) SCR CATALYST ARRANGEMENT
(FR) DISPOSITIF CATALYTIQUE À RÉDUCTION CATALYTIQUE SÉLECTIVE
Abstract
(DE)
Katalysator-Anordnung (1) mit wenigstens einem Wabenkörper (3) mit einem keramischen Trägerelement (8) und einer selektiv-katalytischen Beschichtung (9) sowie einen den Wabenkörper (3)umschließenden Gehäuseabschnitt (2), wobei der Gehäuseabschnitt (2) einen ferritischen Stahlwerkstoff umfasst. Außerdem werden ein besonderer Gehäusewerkstoff und eine große Washcoatmenge für eine SCR-Anwendung vorgeschlagen.
(EN)
The invention relates to a catalyst arrangement (1) comprising at least one honeycomb body (3) provided with a ceramic carrier element (8) and a selectively catalytic coating (9), and a housing section (2) surrounding the honeycomb body (3). The housing section (2) comprises a ferritic steel material. The invention also relates to a specific housing material and a large amount of wash coat for an SCR application.
(FR)
La présente invention concerne un dispositif catalytique (1) comprenant au moins un corps alvéolaire (3) qui comprend un élément de support céramique (8) et une couche catalytique sélective (9), ainsi qu'une section de boîtier (2) qui entoure le corps alvéolaire (3), la section de boîtier (2) comprenant un matériau d'acier ferritique. L'invention concerne également un matériau de boîtier particulier et une grande quantité de wash-coat destinés à une application de réduction catalytique sélective.
