Title
(EN) ARTICLE FOR CARBON MONOXIDE REMOVAL
(FR) ARTICLE SIMPLIFIE DESTINE A L'EVACUATION DU MONOXYDE DE CARBONE
Abstract
(EN)
Provided are improved carbon monoxide removal articles and processes for treating hydrogen gas streams to achieve very low threshold levels of carbon monoxide. The articles have a substrate with an inlet end, an outlet end, a length extending between the inlet end to the outlet end, wall elements and a plurality of cells defined by the wall elements. A first layer (11) is deposited on the wall elements from the inlet end and extending at least partially toward the outlet end. The first layer (13) has a preferential carbon monoxide oxidation catalyst. A second layer contains a methanation catalyst, and is deposited on at least part of the first layer from the outlet end. The second layer has a length that is about 10-70% of the substrate length.

L'invention concerne des articles et des procédés améliorés destinés au traitement des flux d'hydrogène gazeux permettant d'atteindre des taux très faibles de monoxyde de carbone. Les articles ont un substrat possédant une extrémité d'entrée, une extrémité de sortie, une longueur comprise entre l'extrémité d'entrée et l'extrémité de sortie, des éléments de paroi et une pluralité de cellules définies par les éléments de paroi. Une première couche (11) est déposée sur les éléments de paroi à partir de l'extrémité d'entrée et s'étend au moins partiellement jusqu'à l'extrémité de sortie. La première couche (13) comprend de préférence un catalyseur d'oxydation de monoxyde de carbone. Une deuxième couche comprend un catalyseur de méthanation et est déposée au moins sur une partie de la première couche depuis l'extrémité de sortie. La deuxième couche a une longueur qui est d'environ 10 à 70 % de la longueur du substrat.
