  • Process for recovering elemental sulfur by selective oxidation of hydrogen sulfide
    Patent number: 5653953
    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 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.
    Type: Grant
    Filed: August 29, 1995
    Date of Patent: August 5, 1997
    Assignee: National Science Council
    Inventors: Kuo-Tseng Li, Min-Ya Huang, Wen-Da Cheng
  • Selective oxidation of hydrogen sulfide in the presence of bismuth-based catalysts
    Patent number: 5597546
    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.
