ABSTRACT:
The present invention discloses a method of selectively oxidizing hydrogen sulfide to elemental sulfur, in which a H.sub.2 S-containing gas mixture contacts with an oxygen-containing gas at 50.degree.-500.degree. C. in the presence of a bismuth-based catalyst. The reaction product mixture contains substantially no sulfur dioxide. The bismuth-based catalyst may further contain molybdenum or vanadium atom.
