摘要

Producing hydrogen and sulfur from a stream of hydrogen sulfide using a redox cycle on a solid sulfide (metal sulfide (MeS)) according to the reaction as given in the specification, comprises activating solid sulfide performed in an activation reactor (1004) designed to find the conditions for conversion of 70%, absorbing sulfur on the solid sulfide by passing the oxidized form (metal sulfide (MeS)) to the reduced form (MeS2) formed in an absorption reactor (1003) and regenerating the reduced solid (MeS2) for return to the oxidized form (MeS) formed in a regeneration reactor (1006).
