Direct catalytic oxidation of hydrogen sulfide

Hydrogen sulfide-containing natural gases are considered a fundamental sour ce for obtaining elemental sulfur due to depletion of natural reserves. The basic industrial method of extraction of hydrogen sulfide from natural gas es with production of elemental sulfur is the Claus method. The method of p artial catalytic oxidation of hydrogen sulfide, which does not require prel iminary treatment of the gases and concentration of the hydrogen sulfide, i s more promising. This method is being increasingly used in industry.
