The article presents the data of a comprehensive study of three samples of high-viscosity borehole oil of the Tagulskoye field. Using the instrumentation and methodological base of JSC «MidVolgaNIINP», information was obtained on the composition and properties of samples of high-viscosity oil (HVO) after preliminary dehydration and desalination, as well as oil distillate fractions and residues from distillation obtained in laboratory conditions according to GOST 11011, ASTM D 2892/5236. In addition, it is shown that the objects of the study have valuable properties: a low content of total sulfur, a low content of paraffins and a fairly low pour point for heavy oils. The authors have proposed options for further use of the studied objects. In general, valuable basic information has been obtained for the long-term planning of production and the choice of options for the use /processing of unique raw materials.

The work is aimed at developing engineering solutions to upgrade the quality of treated associated petroleum gas as required at design capacity of the unit due to changed composition of supplied gas. Comparative analysis of operation of the unit has been performed using gas composition assumed as engineering documentation was developed and gas composition that has changed in the course of time. Engineering have been developed to optimize the operation of amine treatment section. Design models of gas amine treatment unit have been created in software environment Specialized software. Approaches to selection of process configuration of gas treatment unit have been defined in order to ensure required quality of products at changed composition of associated petroleum gas supplied to processing. Evaluation of economic efficiency of this project has been checked. Taking to account widespread use of amine treatment units at Rosneft’s gas processing facilities, developed engineering solutions may be applied at similar units.

The article presents the results of research on the sintesis of medium alkaline alkylphenolate additives. Additives are calcium salts of the condensation products of alkylphenols with formaldehyde and ammonia or various amines (monoethanolamine, benzylamine and allylamine) have been synthesized and studied. The physicochemical and functional properties of the synthesized products were studied by standard methods.It has been shown that all aminomethyl derivatives of alkylphenols have multifunctional properties and are superior to their analogs ИХП-101, ИХП-109 and ВНИИНП-370 in terms of their functional properties. In addition, the additives obtained on the basis of nonylphenol in terms of anticorrosion and antioxidant properties are somewhat superior to those obtained on the basis of alkylphenol (C8–C12) due to their homogeneous composition. Thus, all synthesized compounds are multifunctional, and additives containing a secondary nitrogen atom (calcium salt of dialkyldioxybenzylamine) and a benzyl radical at the nitrogen atom (calcium salt of N-benzyldialkyldioxybenzylamine) have the highest antioxidant efficiency.

Tests of diesel fuel hydrotreating catalysts have been carried out, which have passed the reactivation procedure according to the technology developed by JSC «all-Russian Oil Refining Research institute». The efficiency of the reactivation technology was evaluated of catalysts for hydrotreating diesel fuels and vacuum gas oil. Based on a comprehensive analysis of the physico-chemical and catalytic properties of regenerated, reactivated and fresh hydrotreating catalysts, the dynamics of changes in the operating characteristics of catalysts is investigated. The results obtained at the pilot plant were confirmed during an industrial run at the L-24/7 hydrotreating plant of JSC «Syzran Oil Refinery». The presented results demonstrate the high activity and stability of reactivated catalytic systems in the process of hydrotreating diesel fuel and vacuum gas oil, in comparison with the results of operation of fresh catalysts of similar brands. I confirm the results of monitoring the operation of reactivated catalytic systems at an industrial technological installation.

An urgent task of the oil refining industry is the development of a thermodestructive process for the processing of heavy oil residues. This paper presents the results of a study of thermal cracking of fuel oil in the presence of aluminocobaltmolybdenum regenerated spent hydrotreating catalyst. The experiments were carried out using an autoclave, as well as using a number of instrumental methods of analysis. The effect of the degree of dispersity and catalyst content on the results of the process under study was studied. The material balance of the thermal cracking process in the presence of catalyst samples of different fractional composition is compared with the material balance of thermal cracking in the temperature range of 450-470 °C. The physical and chemical properties of the samples of catalysts, raw materials and products of the process were determined. The analysis of the obtained experimental data was carried out, the conditions for the most efficient processing of raw materials in the process of thermal cracking in the presence of a catalyst were determined, and conclusions were drawn about the prospects for its use for processing heavy oil residues.

The results of studying of the cycloalkylation reaction of phenol with 3-methylcyclohexene in the presence of zeolite Y impregnated with phosphoric acid are presented. It was found that in order to achieve a high yield (71.2%) and selectivity (93.7%) during the cycloalkylation reaction of phenol with 3-methylcyclohexene, the reaction conditions should be as follows: reaction temperature 120 oC, molar ratio of phenol to 3-methylcyclohexene 1:1, volume velocity 0.5 h-1. The results of the synthesis of 2-hydroxy-5(3-methylcyclohexyl) aceto- and benzophenones by the reaction of p-(3-methylcyclohexyl) phenol with acetic acid (AcOH) and benzoyl chloride (BzCl) with the participation of nanosized ZnCl2 as a catalyst are presented. It was found that at a temperature of 140 oC, a reaction time of 40 minutes, and a molar ratio of p-(3-methylcyclohexyl) phenol to AcOH (BzCl) of 1:2, the yield of the target products was 63.3-66.7%.
