Каталитический Риформинг Бензиновой Фракции Смеси Нефтей Южного Региона Республики Казахстан

Abstract

This article discusses the results of a study of the process of catalytic reforming of straight-run gasoline obtained from a mixture of oil from a field located in the southern region of Kazakhstan. The individual and group hydrocarbon composition of the initial hydrotreated gasoline and reformate was studied in order to establish the degree of conversion of hydrocarbons at different stages of catalytic reforming. The qualitative characteristics of the catalysis of gasoline reforming obtained at different stages of the process allows us to establish the chemistry and reaction mechanism and the laws of the chemical degree of conversion of individual hydrocarbon groups during all stages of catalytic reforming. As a result of studying the process of catalytic reforming of straight-run gasoline fractions НЕФТЕХИМИЯ НЕФТЬ И ГАЗ 2020. 2 (116) 103 О 2 (85–180°С), a chemistry and a reaction mechanism are established that are based on the following reactions: dehydrocyclization of paraffin hydrocarbons, dehydrogenation and dehydroisomerization of naphthenic, isomerization of naphthenic and paraffin hydrocarbons. Comparison of the physicochemical properties and group hydrocarbon composition of the hydrogenate and reforming products shows that the amount of n-paraffin and naphthenic hydrocarbons after catalytic reforming is reduced by 3–4times than in the originalgasoline, and the concentration of aromatic hydrocarbons is significantly increased due to the cyclane dehydrogenation reaction and dehydrocyclization of normal paraffins. Set forth in article information on changing the group and individual hydrocarbon composition of gasoline in various stages of the catalytic reforming process, can serve as a basis for optimal control of technological process of catalytic reforming and is a priority in the production of highquality grades of motor fuel and petrochemical development in the processing of local oil and gas Republic of Kazakhstan.
