Characteristics of Carbon-Based Catalysts for the Selective Catalytic Oxidation of Hydrogen Sulfide
نویسندگان
چکیده
The development of low cost, highly efficient, desulfurization technology with integrated sulfur recovery remains a principle barrier issue for integrated gasification combined cycle power generation plants. For coal-derived synthesis gases with low sulfur content, direct air injection can be utilized to selectively oxidize the hydrogen sulfide present into elemental sulfur via the reaction H2S+1/2O2 → S+H2O. The sulfur product that is formed may then be removed as a condensed phase. By performing this reaction at temperatures between 150 and 280°C, CO and H2 components of the coal-derived synthesis gas and the product sulfur pass through un-oxidized.
