Abstract:
The possibility of the formation of polysulfides during oxidation of H2S with oxygen on oxide catalysts has been checked, and the sequence of the reaction stages at temperatures below the sulfur dew point determined. The amount of polysulfides formed during H2 S oxidation has been found to exceed significantly that obtained in the reaction of sulfur with H2 S. Polysulfides are concluded to be intermediates in H2 S oxidation to sulfur. The rate of formation of SO2 from sulfur vapor is shown to be negligibly low at 100-200°C. A reaction scheme involving the formation of sulfur from polysulfides and the formation of sulfur dioxide by direct oxidation of H2S is suggested.
