Risk Research by Mathematical Modeling to Increase the Life Cycle of Catalysts Used in Modern Refineries

This article discusses the results of a study of the effect of the size of a platinum-containing catalyst onthe characteristics of coke fragments and the method of mathematical modeling of coke burning in the process of oxidative regeneration both at catalytic reforming plants and at catalytic cracking plants, in order to reduce the risks of premature loss of the life cycle of expensive catalysts used at modern refineries.The revealed kinetic patterns obtained during the study of coke burning of a platinum-containing catalyst allowed us to propose a new reaction mechanism. Stoichiometric ratios describing individual reactions are compiled. Based on the proposed mechanism,kinetic equations for routes are adopted. Based on the obtained system of kinetic equations and assuming the absence of radial temperature gradients, concentration and rate of the process with heat removal, the heat balance equation is proposed. The parameters of the model are considered as factors of risk analysis of technological processes atthe refinery enterprises. The versatility of the developed mathematical model of the process makes it possible to apply it to solving problems of managing both reforming and cracking installations, in order to reduce risk factors
