Hydrogen and sulphur production by indirect electrolysis of hydrogen sulphide

Producing hydrogen and sulfur by indirect electrolysis of hydrogen sulfide is a new method by which H2S resource will be used more efficiently. This method consists of an absorption process and all electrolytic regencration of absorbent process. The ratio of H2S absorption and electricity consumption of hydrogen production has been researched. The results show that: the H2S absorption ratio of model gas is about 99%, at 80 degrees C, normal atmosphere and the electricity consumption of hydrogen production call be reduced to 2.0kWH/(NMH2)-H-3. The effects of olefin and carbon dioxide of H2S model gas have been also studied.
