The present invention relates to a method for processing a sulfur-containing gas and a hydrogenation catalyst used therefor. Said method comprises introducing the sulfur-containing gas into the tail gas hydrogenation unit of a sulfur recovery device, processing it with the hydrogenation catalyst of the present invention, absorbing the hydrogenated tail gas with a solvent and then regenerating, the regenerated hydrogen sulfide being recycled to the Claus unit to recover sulfur, the clean tail gas being incinerated in an incinerator to be discharged after reaching the standards. Said sulfur-containing gas comprises from 0 to 6 vol. % of sulfur dioxide and from 0 to 3 vol. % of oxygen, and has a temperature of from 100 to 200° C. The hydrogenation catalyst of the present invention comprises from 0.5 to 3 wt. % of an active component nickel oxide, from 1 to 4 wt. % of an active component cobalt oxide, from 8 to 20 wt. % of an active component molybdenum oxide or tungsten oxide, from 1 to 5 wt. % of a deoxidation auxiliary agent, from 10 to 40 wt. % of TiO2, the balance being gamma-Al2O3, based on the weight of the catalyst.
