Abstract

A process for desulfurization of fuel or synthesis gases containing carbon oxysulfide wherein the carbon oxysulfide is hydrolyzed by treating the gas at a temperature of 50.degree. to 105.degree.C with a low-volatility organic solvent inert to the carbon oxysulfide and containing 15 to 50 mole-percent water, the hydrolysis products and other sulfur-containing compounds being removed by subsequent scrubbing of the gas.
