An approach to modeling the isomerization process implemented in the technological scheme with the maximum normal paraffins conversion was described. The comprehensive mathematical model was designed as a powerful tool for optimization. It is based on the influence of the feedstock composition for assessment of the current catalyst activity. According to the calculations, the optimal operating parameters are determined by the refined feedstock composition

Abstract. An approach to simulation of hydrocarbons refining processes catalytic reactors. The kinetic and thermodynamic research of light naphtha isomerization process was conducted. The kinetic parameters of hydrocarbon feedstock chemical conversion on different types of platinumcontent catalysts was established. The estimation of efficiency of including different types of isomerization technologies in oil refinery flow diagram was performed.
