3 principle

Raw material gas sulfur dioxide and hydrogen under the action of the catalyst, the chemical reaction occurs to generate hydrogen sulfide and water; the raw material gas disulfide Under the action of the catalyst, carbon and water are hydrolyzed to form sulfur and hydrogen sulphide, and sulfur and sulfur oxides are hydrolyzed to form hydrogen sulphide and carbon dioxide. Its The reaction equation is as follows. SO2 3H2 ≒ H2S 2H2O CS2 H2O ≒ COS H2S COS H2O ≒ H2S CO2 Using gas chromatography analysis of the volume fraction of sulfur dioxide, carbon dioxide and carbon disulfide in the gas before and after the reaction, to calculate the sulfur dioxide turn The conversion rate and the organic sulfur hydrolysis rate, in order to characterize the catalyst activity.
