This paper develops the effectiveness factors of catalysts for two reaction models and shows that this factor is dependent not only upon size, shape, effective diffusivity and surface reaction velocity constant, but also upon the reaction model, surface coverage by adsorption, degree of conversion a

The influence of a resistance to reactant adsorption on the multiplicity and stability of the steady state of a catalyst particle, promoting an exothermic reaction, is considered. For activated adsorption new regions Bfmultiplicity are uncovered in the parameter space. It is shown that multiple solu
Tke dusty gas model is used to establish the effects of temperature and pressure gradients on catalyst pellet effectiveness factors for reaction systems in which species molecular weights and transport coefficients are indistinguishable and Lui = 0. For this class of reactions, the total molar flux
