Hydrogen production by steam–iron process
The process operates two stages: during the reduction step the iron ores 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, the iron ore is re-oxidised by water vapour yielding an hydrogen rich fuel gas.
