Abstract
A process for the production of hydrogen and oxygen from water comprising the steps of forming ferric chloride from ferriferrous oxide by reaction with a chloride ion yielding substance, thermally reducing the ferric chloride to produce ferrous chloride, reducing the ferrous chloride to metallic iron, then oxidizing the metallic iron with water so as to produce hydrogen. The metallic iron may be formed by reducing the ferrous compound with hydrogen. Two specific reactant regenerative closed cycle systems are disclosed utilizing the process of this invention for the production of hydrogen and oxygen.
