Abstract
In this short communication, the modified dusty-gas model1-3 is used to describe the mass fluxes and to estimate the effectiveness factors in the transition regime of second order irreversible reactions with mole changes in heteroporous media. The results of this note show that the effectiveness factors predicted by the dusty-gas model are larger (up to about 30% for the systems examined) than those estimated by the modified dusty-gas model which accounts for the effects the pore-size and tortuosity distributions have on the mass fluxes in industrial heteroporous catalysts.Keywords
