Some epistemological problems of mathematical modeling of diesel fuel hydrotreating process

Abstract

The article discusses the features of modeling a complex multicomponent process of hydrodesulfurization of diesel fuel. It is shown that the meaning of a number of parameters, in particular, the rate constants of hydrodesulfurization reactions used in mathematical modeling of diesel fuel hydrotreatment, does not correspond to the real laws of physico-chemical processes, while the proposed numerical values of these parameters are acceptable only for describing those specific processes in the course of which they were obtained. The concept of kinetic characteristics and modification of the calculation of the reaction rate constant are proposed.
