Process for recovering elemental sulfur by selective oxidation of hydrogen sulfide

摘要

The present invention discloses a method of selectively oxidizing hydrogen sulfide to elemental sulfur, in which a H2S-containing gas mixture contacts with an oxygen-containing gas at 50 DEG -500 DEG C. in the presence of a mixed-metal catalyst. The reaction product mixture contains substantially no sulfur dioxide. The mixed-metal catalyst contains vanadium atom and molybdenum atom or magnesium atom.
