Steam oxidation of porous reduced iron, prepared by hydrogen reduction of iron oxide sintered with inert silica, was carried out under conditions of temperature 460-700°C and steam partial pressure 0.002-0.02 MPa. The oxidation reaction could be represented by a two-stage reaction. In the first stage, iron is oxidized to magnetite. After the completion of the first-stage reaction, magnetite is slowly oxidized to hematite. In the first-stage oxidation reaction, which is the main reaction to produce hydrogen, the initial activity of solid material did not change in the reduction-oxidation cyclic operation. The initial conversion rate could be represented by a Langmuir-Hinshelwood type equation containing the adsorption term of water vapor.
