ABSTRACT:
A hydrogen sulfide gas is converted to sulfur and hydrogen gas by reacting the hydrogen sulfide and with an anthraquinone dissolved in a polar hydrocarbon solvent. The hydrogen sulfide reacts with the anthraquinone to produce sulfur and an anthrahydroquinone. Sulfur is then removed from the solvent. The anthraquinone is regenerated from the anthrahydroquinone yielding hydrogen gas. The anthraquinone is recycled with the solvent to the reaction.
