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, reducing the ferric chloride produced with a reducing agent to produce ferrous chloride, thermally reducing the ferric chloride to produce ferrous chloride, then oxidizing either the ferrous compound or metallic iron with water so as to produce hydrogen. The metallic iron may be formed by reducing the ferrous compound with hydrogen. Four specific reactant regenerative closed cycle systems are disclosed utilizing the process of this invention for the production of hydrogen with high energy efficiencies.
