There is provided a catalyst for removing carbon monoxide that has a high CO gas adsorption amount, is highly active even at low temperatures, and can selectively methanate carbon monoxide (methanation). One or more metals selected from Group 4B, Group 6A, Group 7A and Group 8 are supported on zeolite as an active component, and the metal content in the catalyst is 0.5 to 15% by weight. A catalyst for carbon monoxide methanation characterized by being in the range. The present invention relates to a carbon removal method in which the zeolite is at least one selected from ZSM-5 type zeolite, mordenite type zeolite, faujasite type zeolite, and β zeolite.
