Popis: High-quality processing of petroleum feedstock and gas condensates from the Zhanazhol field will satisfy the demand for high-quality motor and boiler fuel, lubricating oils, petroleum coke, petrochemical synthesis raw materials. Satisfaction of the needs of various industrial sectors and the population in high-quality raw materials requires the development of petrochemical production that approaches European standards. The main consumers are cars and trucks, railway and water transport, as well as various power generators, military and agricultural equipment. In addition to the demand in the products themselves, the demand for fuel quality is also growing, which must not only meet the stringent requirements of world standards, but also have the quality characteristics of raw materials that satisfy the content of sulfur, polycyclic aromatic hydrocarbons, as well as possess a number of low-temperature properties. The purpose of the research is to develop individual approaches to the use of gasoline fractions of oil from the Zhanazhol field as a raw material for the process of hydrocatalytic isomerization, as well as the use of an isomerized product as a component for obtaining clean ecological commercial gasoline. Composition, indicating the potential content of petroleum products and various impurities. As well as a method for describing the technological process of catalytic reforming or hydrocatalytic isomerization of gasoline fractions of oil. The study of the Zhanazhol oil and gas condensate field established specific features of the physicochemical properties of oil with a high content of hydrogen sulfide and carbon dioxide, paraffin hydrocarbons, and the transformation of n-alkanes of the gasoline fraction. Special systems for the collection and treatment of oil, gas, water, and installations for sulfur decanting in a corrosion-resistant state were formed based on the chemical properties of this raw material. The effectiveness of the use of catalytic reforming, under the best conditions of the process, aimed at obtaining low-solidification fuels of petroleum feedstock, has been proven. The use of aluminum-platinum catalysts from high-temperature to low-temperature isomerization is characterized. The optimal technological parameters for the use of catalytic systems have been determined. The practical significance of the research lies in the fact that during the hydrocatalytic isomerization of raw materials with a significant sulfur content, the catalyst quickly becomes intoxicated, so it is advisable to subject it to hydrotreatment, which increases the technical and economic performance of the processing unit. Efficient catalytic systems have been selected that carry out the process of isomerization of the pentane-hexane fraction under various temperature conditions. The optimal technological parameters of their use were determined. The research results can be used to calculate the mass and energy balance of the catalyst regeneration process.
