Abstract

A mathematical model of a bifunctional catalyst for the process of hydrocarbon isomerization is proposed, taking into account the composition of the reaction mixture, as well as the ratio of metallic and acid active centers. The elementary surface processes are considered: adsorption/desorption of reagents, dehydrogenation of paraffin into olefin, isomerization of olefins, cracking, hydrogenation of isoolefins and unsaturated low molecular weight cracking products, desorption of reaction products, coke formation, diffusion of adsorbed particles. The given amounts of desorbed reaction products are calculated. Snapshots of the catalyst surface were obtained.
