Abstract: A method for treatment of a gas having 10 to 0.5% by volume of at least one of COS and CS2, and 30 ppm to 5% by volume of unsaturated hydrocarbons: a) hydrogenation of organic compounds unsaturated with respect to paraffins by contacting the gas with a hydrogenation catalyst in the presence of hydrogen at 100 to 400° C., to provide an effluent that is low in unsaturated hydrocarbon compounds, the hydrogenation catalyst having at least one metal that is palladium, platinum, nickel, or cobalt deposited on a porous substrate. b) catalytic hydrolysis-hydrogenation in the presence of water of COS and/or CS2 present in the effluent of a) to provide an H2S-rich effluent by bringing the effluent from a) into contact with a hydrolysis-hydrogenation catalyst.

Abstract: The present invention relates to a process for treating a gas containing from 10 ppm by volume to 0.5 volume % of at least one of the compounds COS and CS2 and from 30 ppm by volume to 5 volume % of unsaturated hydrocarbon compounds, the said process comprising the following stages:(a) a hydrogenation of the unsaturated organic compounds to paraffins is carried out by contacting the said gas with a hydrogenation catalyst in the presence of hydrogen, (b) a catalytic hydrolysis of COS and/or CS2 present in the gaseous effluent from stage a) is carried out in the presence of water and a hydrolysis catalyst.
