PROBLEM TO BE SOLVED: To provide a catalyst for removal of carbon monoxide in hydrogen- containing gas having high selectivity for the methanation reaction of carbon monoxide as the main reaction and to provide a method for removing carbon monoxide in hydrogen-containing gas by using the above catalyst. SOLUTION: The catalyst for removal of carbon monoxide in hydrogen- containing gas by methanation of carbon monoxide is prepared by depositing ruthenium nitrate (a) on a refractory inorganic oxide carrier, drying and reducing without calcination. The obtained catalyst is used for the method for removing carbon monoxide in hydrogen-containing gas. |
