Abstract
A method of producing hydrogen gas and separating sulfur from hydrogen sulfide including contacting the hydrogen sulfide with a catalyst in an aqueous solution to form a hydrogen gas and a reaction solution including sulfur; mixing the reaction solution and a sulfur solvent to form a sulfur solution; separating the sulfur solution into a first stream including the aqueous solution and a second stream including sulfur; and precipitating sulfur from the second stream.
