Abstract
Hydrogen and sulfur are produced from hydrogen sulfide by reacting the latter with iodine in an aqueous solution of hydriodic acid, recovering the sulfur thus formed, removing any unreacted hydrogen sulfide from the solution, rectifying said solution thereby to obtain hydrogen iodide and a residual hydriodic acid solution and thermally dissociating the hydrogen iodide to form hydrogen and iodine. The hydrogen is separated by diffusion and recovered. The unreacted hydrogen sulfide thus removed, the residual solution and the iodine are recycled.
