The experiments of the reduction of iron oxide pellets using gas mixture in a laboratory scale moving bed reactor were carried out under various pressures. It was found that the effects of side reactions such as the water-gas shift reaction and formation and decomposition reaction of methane on the operational results increased as pressure increased. These results required the rigorous evaluation of the reaction rates of side reactions. With this in mind, the fundamental experiments were carried out by using the fixed bed reactor with the catalyst of reduced iron pellets and some kinds of iron oxide pellets. The reaction rates of side reactions were measured under the temperature and pressure range of 773-1273K and of 0.142-1.033 MPa respectively. And the reaction rate constants of these reactions were calculated. The qualitative behavior of the side reaction observed in the moving bed was reasonably explained by the kinetics obtained.
