Process for producing hydrogen from water. [ferriferrous oxide and a chloride ion yielding substance]
Patent
·
OSTI ID:7349969
A process is given 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, and then oxidizing the ferrous compound with water so as to produce hydrogen. Suitable reducing agents include cuprous chloride, chromous chloride and platinum. Several reactant regenerative closed cycle systems are disclosed utilizing the process of this invention for the production of hydrogen with high energy efficiences. 15 Claims, 4 Drawing Figures.
