ABSTRACT:
A process for purifying a gas containing hydrogen sulfide, wherein 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.degree. to 170.degree. 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.degree.-300.degree. C. in the presence of oxygen, the regenerating conditions being such as to avoid a substantial oxidation of the carbon mass.
