Hydrogen gas is one of key materials for promotion of the utilization of energy with low environmental load. Ironmaking and steelmaking processes produce enormous thermal energy during steel production, most of which are not used before final dissipation to natural environment. In the present study, the environmental-friendly H2 gas production process by converting H2O gas with FeO and thermal energy in steelmaking slag has been proposed, and physicochemical properties of reaction between FeO-containing steelmaking slag and H2O-containing gas have been estimated by applying thermodynamic calculation. The effects of slag temperature and compositions, gas temperature, and partial pressure of H2O on production behavior of H2 gas have been investigated.
