Abstract
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 is deposited on the wall elements from the inlet end and extending at least partially toward the outlet end. The first layer 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.
