A basic research on the production of partially reduced iron by heating iron ore-coal char composite pellet was conducted by using a pellet in oxygen bearing gas flow. Oxygen in the reaction gas generates heat by combusting carbon to very efficiently compensate the heat consumed by the strongly endothermic reaction of carbon C+CO2=2CO, while oxygen also re-oxidized reduced iron. A simple non-isothermal model for the reaction was made to simulate the very complicated phenomena. We approximated the reduction of iron oxides and the gasification of carbon to be of first-order one-step reaction, respectively. Further we assume that the shrinking-core model is applicable to the penetration of oxygen into the pellet under the diffusion limit of oxygen in the gas film and the re-oxidized product shell. By applying the reaction model, we succeeded in simulating the experimental results.
