FIELD: chemistry.
SUBSTANCE: invention relates to a method of treating a sulphur-containing gas and a hydrogenation catalyst used therefor. Described is a hydrogenation catalyst which includes, as an active component, nickel oxide, cobalt oxide and molybdenum oxide or tungsten oxide. One or more compounds selected from iron (II) sulphate, iron (III) nitrate and iron (III) sulphate are added as a deoxidising auxiliary agent. TiO2 and γ-Al2O3 are added in the form of a dry colloid of a titanium-aluminium compound. Also described is a method of treating a sulphur-containing gas with a hydrogenation catalyst.
EFFECT: catalyst has high sulphur dioxide hydrogenation activity and a low operating temperature.
