    A mathematical model for the kinetics of reduction of porous wustite pellets with CO-H//2 gas mixtures was developed on the basis of the unreacted core model. In this model, the water-gas shift reaction with reduced iron as a catalyst was taken into consideration. The diffusion rates of gases through the gas film and the iron layer were evaluated using the Stefan-Maxwell equations for multi-component gas diffusion. Porous wustite pellets were reduced with CO-H//2 gas mixtures (5Nl/min) at 900 degree C. Experimental data were analyzed by the model.
