ABSTRACT:
A process for reducing the sulfur content of coke oven gas containing hydrogen sulfide, organo-sulfur compounds, and at least one inorganic carbon-sulfur compound, comprises treating the gas stream to remove most of the hydrogen sulfide and then catalytically hydrogenating and/or hydrolyzing the organo-sulfur and carbon-sulfur compounds at an elevated temperature and a partial hydrogen pressure of at least 10 psia, followed by extraction of the remaining and formed hydrogen sulfide.
