Electrochemical process for decomposing hydrogen sulfide to produce hydrogen and sulfur

摘要

A process is described for decomposing hydrogen sulfide to produce hydrogen and sulfur. The process comprises mixing hydrogen sulfide with a volatile basic solution and introducing this mixture into an electrolytic cell having an anode and a cathode. By operation of this cell, hydrogen is formed at the cathode and a solution containing polysulfide is formed at the anode. The polysulfide-containing solution is separated and distilled to recover sulfur and the remaining volatile basic solution is recycled to be mixed with further hydrogen sulfide.
