| 发明名称 | Method for regenerating COS hydrolysis catalyst | ||
| 摘要 | A method for regenerating a carbonyl sulfide (COS) hydrolysis catalyst for hydrolyzing COS which is contained in a gas obtained by gasifying a carbon material, wherein a spent COS hydrolysis catalyst is immersed in an acid solution for a prescribed time thereby removing poisoning substances adhering to the surface of the COS hydrolysis catalyst; and thus regenerating the COS hydrolysis catalyst. | ||
