Chemical Reactions With Mole Changes In Heteroporous Catalysts—Part I
Abstract
The modified dusty-gas model1.2 is used to describe the mass fluxes for zero and first order irreversible reactions with moles changes in heteroporous catalysts, and to estimate their effectiveness factors in the transition regime. It is shown that the effectiveness factors predicted by the dusty-gas model (homoporous model) are larger than those calculated by the modified dusty-gas model (heteroporous model), in some cases by about 30%. In the Knudsen and molecular regimes, the correction factors of the modified dusty-gas model approach unity and the two models predict the same values for the effectiveness factors. Since many industrial catalysts are heteroporous and operate in the transition region of transport, the transport equations and calculational procedures presented in this work are relevant to reactor design. © 1984, Taylor & Francis Group, LLC.
