Nickel Molybdenum Hydrodesulfurization Catalyst is used for hydro conversion of organic sulfur in the coken oven gas, refinery gas and natural gas. Meanwhile, the olefins contained in the gas are hydrogenated to protect the normal use of various catalysts in the post-stage.

The reaction is summarized as below:

COS+H 2 =CO+H 2 S CS 2 +4H 2 =CH 4 +2H 2 S

C 2 H 5 SH+H 2 =C 2 H 6 +H2S CH 3 SCH 3 +2H 2 =2CH 4 +H 2 S

C 4 H 4 S+4H 2 =C 4 H 10 +H 2 SC n H 2n +H 2 =CnH 2n+2
