Abstract

The first object is to increase the life of a selective CO methanation catalyst, and the second object is to enhance the CO removal rate of a selective CO methanation catalyst to reduce the outlet CO concentration in a wide temperature range. Provided a selective CO methanation catalyst including a supported metal catalyst which selectively methanizes CO in a hydrogen-rich gas containing CO and COand a coating layer which covers a surface of the supported metal catalyst, has many pores, and is configured to reduce a CO concentration on the surface of the supported metal catalyst.
