ABSTRACT:
A process is provided for removing sulfur compounds, such as carbonyl sulfide, carbon disulfide, mercaptans and hydrogen sulfide out of a gas, such as methane, carbon dioxide, carbon monoxide, nitrogen and methane, by saturating the sulfur compound contaminated gas with steam; hydrolyzing any carbonyl sulfide, carbon disulfide and mercaptans in the gas stream into hydrogen sulfide by contacting the steam and sulfur compound contaminated gas with a catalyst containing an inorganic support uniformly impregnated with a mixture of at least one oxide selected from Group VI transition metals and at least two oxides selected from Groups I, II, VI and VIII transition metals at a temperature of about 20.degree. C. to about 150.degree. C.; oxidizing the hydrogen sulfide in the gas exiting the previous hydrolysis step by contacting the hydrogen sulfide containing gas together with at least a stoichiometric quantity of air and/or oxygen with the catalyst at a temperature of about 15.degree. C. to about 50.degree. C. to produce a sulfur loaded catalyst and a desulfurized gas. The sulfur loaded catalyst may be regenerated with steam.
