摘要：
A process is disclosed for the removal of sulphur compounds from a residual gas so as to obtain a purified gas stream substantially free of sulphur compounds, which process comprises subjecting the residual gas to a combined hydrogenation and hydrolysis, cooling the gas to a temperature whereby water vapor in the gas is not condensed, mixing the gaseous effluent with a gas containing free oxygen, contacting the cooled gaseous effluent and the gas containing free oxygen with a catalyst for selective oxidation of H.sub.2 S to sulphur, and depositing substantially all of the sulphur formed on the catalyst.
