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. |
