✦ Synopsis

Accurate simulation of fixed-bed catalytic reactors requires the computation of the effectiveness factors at each point along the length of the reactor. This requires the formulation and solution of rigorous diffusion-reaction models for the porous pellets based on the more rigorous Stefan-Maxwell equation for multicomponent diffusion rather than the approximate Fick's law formulation . The conversion attainable from some dehydrogenation reactions is sometimes limited by the thermodynamic equilibrium. An attractive technique for breaking this limitation is through the use of selective membranes in order to remove at least one of the products from the reaction mixture
