Beschreibung
Zusammenfassung:	The invention is directed to a process for the purification of a raw hydrogen gas stream comprising hydrogen gas in an amount of 85-99%, said process comprising the step of contacting said raw hydrogen gas stream with an oxidized bed comprising an oxidized metal resulting in a waste gas stream comprising water and less than 5% hydrogen gas, and in a reduction of said oxidized metal; and a step of contacting a bed comprising a reduced metal with water to produce a purified hydrogen gas stream comprising more than 99% hydrogen gas, preferably comprising 99.97% or more hydrogen gas, and the oxidized metal. In a further aspect, the invention is directed to an apparatus suitable to carry out said process.
