hydrogen production by steamndash iron process

Mar 01, 2000· Theprocessoperates two stages: during the reduction step theironores are reduced by synthesis or biomass gas, which is thereby oxidised to a lean gas with low remaining CO (6–8%) and H 2 (ca. 6%) content. In the subsequent oxidation step, theironore is re-oxidised by water vapour yielding anhydrogenrich fuel gas.

The steam-iron processis one of the oldest methods of producinghydrogen. It is a cyclicprocessfor water cleavage, whereby coal is consumed. Coal is gassified to a lean reducing gas, containing carbon monoxide andhydrogen. This gas reacts withironoxides (haematite Fe 2 O 3 , magnetite Fe 3 O 4 >, wuestite FeO) to produce a reduced form ofironoxide (wuestite FeO,ironFe).
