Abstract

The main schemes of transformations of the catalytic isomerization of the pentane-hexane fraction are considered. A mathematical model of the reactor block of the process under study has been developed, describing in detail the chemical reactions inside the reactors. The values of kinetic parameters (activation energy of stages, pre-exponential factors of the Arrhenius equation) are calculated by solving the direct and inverse problems. Based on the developed mathematical model, the problem of multi-criteria optimization of the reactor block of the process is solved. Mathematical descriptions of optimization criteria for the used model are proposed. Temperature modes of operation of the reactor block that meet the optimality criteria are presented.
