抄録

In this heterogeneous multi-reaction system, kinetic steps in each group of heat transfer, mass transfer and chemical reactions are investigated first to identify the slowest step based on a validated mathematical model of 19 independent equation.^{2, 3)} They are conductive heat transfer, convective mass transfer and carbon gasification by CO₂ and H₂O. The overall reaction of metallization of iron ore by coal with heat supplied by an external source is largely limited by the conduction of heat though the sponge iron shell of an ore/coal composite.
