An important problem of oil refining related to the production of diesel fuels with specified properties is considered. The technology of production of hexadecane isomer in a laboratory setup is chosen as an example. A material based on aluminophosphate is used as a catalyst. An original complex three-dimensional mathematical model is proposed for this physico-chemical problem. The model includes a quasi-hydrodynamic system of equations for calculating the flow of a multicomponent two-phase medium and convection-diffusion-reaction equations for calculating the dynamics of concentrations of the feedstock and reaction products. The numerical implementation of the model uses methods of splitting into physical processes and finite volumes. To speed up the calculations, a parallelization procedure based on the domain decomposition technique is applied. Numerical experiments demonstrate the efficiency of the developed computing technology. Keywords: oil refining, catalytic isomerization reactions, quasi-hydrodynamics, convection-diffusion, three-dimensional computer modeling.
