Kinetic Model of Catalytic Gasoline Reforming with Consideration for Changes in the Reaction Volume and Thermodynamic Parameters

For an industrially significant process of the catalytic reforming of gasoline, an increase in the octane number of gasoline and limitations on the concentrations of aromatic hydrocarbons and benzene are the most important problems. To solve these problems, an analysis of the reactor unit based on a detailed kinetic model of the process was proposed. In the grouped kinetic model of the catalytic reforming of gasoline, changes in the volume of the reaction mixture in the course of chemical transformations were taken into account. For the process of catalytic gasoline reforming, an algorithm was formulated and thermodynamic parameters were determined for grouped individual hydrocarbons. The inverse kinetic problem of restoring the kinetic parameters of stages was posed for the developed mathematical model. The residual functionals that take into account the experimental data on component concentrations and temperature changes during the entire process were determined. The concentrations of the group components in the catalytic reaction of gasoline reforming and the full temperature profile of the process were calculated. The results of solving the two-criterion optimization problem for a minimum concentration of aromatic hydrocarbons at a maximum octane number of the reformate based on the developed kinetic model are presented.
