Wet oxidation hydrogen purification

A process for producing a stream of pure hydrogen, said process comprising the steps of:

• a) contacting a raw hydrogen gas stream comprising hydrogen gas in an amount of 85-99 mol % with an oxidized bed comprising an oxidized metal, at least resulting in a waste gas stream comprising water and less than 5 mol % hydrogen gas, and in a reduction of said oxidized metal to produced a reduced metal;
• and
• b) contacting a bed comprising the reduced metal with water to at least produce a purified hydrogen gas stream comprising more than 99 mol % hydrogen gas, and oxidizing the reduced metal to form the oxidized metal wherein said raw hydrogen gas stream further comprises one or more further reducing gases, and wherein step a) includes oxidizing said reducing gas to a higher oxidation state utilizing the oxidized bed.
