Method for processing hydrogen sulfide gas using water mist and water vapour as catalyst

The invention provides a method for processing hydrogen sulfide gas using water mist and water vapour as catalyst. The invention employs water mist and water vapour as catalysts for ensuring hydrogen sulfide to react with sulfur dioxide, and the optimum reaction temperature is 50-60 DEG C. The conversion rate of sulfur reaches to about 90%. The invention employs water mist and water vapour as catalysts, and is used for hydrogen sulfide pollution treatment and multipurpose use of waste. The invention provides an economic and practicable technology route of circular economy development.
