Abstract
The method for regenerating a carbonyl sulfide (COS) hydrolysis catalyst according to the present invention is a method for regenerating a Ba/TiObased carbonyl sulfide (COS) hydrolysis catalyst by hydrolyzing COS which is contained in a gas obtained by gasifying a carbon raw material, wherein a spent COS hydrolysis catalyst is washed with water, dried, immersed in an aqueous solution of a barium salt for a prescribed amount of time, dried, and calcined so as to re-support the active component on the surface of the COS hydrolysis catalyst, thus enabling the regeneration of the COS hydrolysis catalyst.
