A process is disclosed for purifying a gas containing hydrogen sulfide. Said gas is admixed with oxygen and contacted with a carbon mass of specific surface higher than 50 m2/g and containing at least one oxide and/or sulfate of iron and/or copper, at a temperature from 20/sup 0/ to 170/sup 0/ C, the operating conditions being so selected as to avoid a substantial oxidation of said mass and said mass being periodically regenerated by heating to 200/sup 0/-300/sup 0/ C in the presence of oxygen, the regenerating conditions being such as to avoid a substantial oxidation of the carbon mass.
