METHOD FOR MANUFACTURE OF HYDROGEN AND CARBONYL SULFIDE FROM HYDROGEN SULFIDE AND CARBON MONOXIDE

摘要

Hydrogen is produced from hydrogen sulfide by using, as a catalyst, the sulfide of a metal selected from the class consisting of transition metals of Group V such as vanadium, of Group IV such as molybdenum, tungsten and chromium and of group VIII such as iron, cobalt, nickel, palladium and rhodium of the Periodic Table of the Elements. When hydrogen sulfide is supplied to a reaction system using therein the said catalyst, it is separated into hydrogen and sulfur and the sulfur thus separated is deposited and accumulated on the catalyst. Regeneration of the catalyst is accomplished by causing carbon monoxide or nitrogen monoxide to react on the deposited sulfur so that the sulfur is removed from the catalyst in the form of carbonyl sulfide or nitrogen oxysulfide.
