Abstract

A mathematical model that adequately describes the process of catalytic reforming—the main industrial technology for obtaining high-octane components of motor fuels in Russia and abroad is presented. The necessity of expanding the existing scheme of transformations of hydrocarbons of the gasoline series to create a model of reforming feedstocks of various origins (gasoline fractions of thermal destructive processes, hydrocracking naphtha, gas condensate) is shown. Based on the results of experimental studies using gas chromatography, as well as the calculations of thermodynamic parameters, an improved formalized reaction scheme has been compiled to take into account into account reactions involving unsaturated hydrocarbons. A kinetic model of the reforming process of the expanded gasoline fraction has been compiled. To describe the kinetic model based on the formalized scheme of hydrocarbon transformations, a matrix method was used, which makes the model more flexible to the composition of the feedstock.
