Abstract
Results from calculating the thermochemical properties of molecules and the thermodynamic characteristics of vacuum distillate hydrotreatment reactions by quantum-chemical methods are presented. A mathematical hydrotreatment model is developed on the basis of a formalized scheme of reactions for hydrocarbons. The developed kinetic model is used in numerical studies to estimate the effect of the feedstock composition on the residual content of heteroatomic compounds in the vacuum gasoil hydrotreatment product, the effect of the temperature on the content of aromatic hydrocarbons, nitrogen, and sulfur in the hydrotreatment product, and flow rate of the hydrogen-containing gas on the content of sulfur and hydrogen sulfide in hydrotreated vacuum gasoil.
