Structural-group composition of the raffinate obtained by selective purification of the oil fraction, extracted from the oil of balakhany oil field
Keywords: hydraulic fluid, distillate extraction cleaning, raffinate, ionic liquid, hydrocarbon composition.
Abstract. In the presented article, the results of the research using the IR and NMR spectral methods of the structure composition of the base product of AMQ-10 named hydraulic fluid, which was obtained from Balakhani oil fraction (BP range 234-306°C) by selective treatment using N-methylpyrrolidonacetate based ionic liquid, were given.The distillate used in the research is characterized by the following characteristics:
density at 850 kg/m3 at 20°C, kinematic viscosity at 2.3 mm/s at 50°C, ignition temperature — 110°C, freezing temperature — minus 75°C and aromatic hydrocarbons — 14% mass. For comparison, the hydrocarbon group composition of the raffinate extracted from the selective treatment of the oil fraction by organic soluble N-methylpyrrolidone which mentioned in the article and acid contact method
were also investigated by IR and UB spectral analysis methods. It has been determined that absorption strips reflecting rate of the C-H bond in the aromatic ring (1604 cm-1) and the C-H bond in the CH2 (968cm-1) of hybrid naphthenic aromatic hydrocarbons is reduced in the samples taken from the extracted oil fraction. This has also been confirmed by the calculated values of the optical density of the absorbed strips. Thus, in raffinate extracted from selective treatment, the absorption strips in the 1031 cm-1
area was observed like feedstock. In additionally, the absorption strips rate of naphtha fragment and benzene ring decreased from 0.009 to 0.007 in the 968 and 1604 cm-1 area respectively, which indicated that aromatic and naphthenic aromatic hydrocarbons was removed by selective treatment process. UF spectral analysis of the raffinate samples which taken from selective treatment, demonstrates that the amount of the aromatic hydrocarbon decrease from 14.4% to 0.64-0.95%. In other words, the use of the ionic liquid composition as a selective solvent is more prospective. Finally, according to the results of UB spectral analysis of the raffinate, the aromatic hydrocarbon weight amount is 2.56% (extracted from Balakhani oil fractions by using organic solvent N-methylpyrrolidone) and 2.5% (obtained by acidic contact treatment method). In addition, ionic liquid extraction is relatively predictive because of the ionic liquid composition is ecologically harmless and also useful as an extractant after

Tb- and Pr-containing polyoxotungstates as catalysts in the epoxidation of styrene with hydrogen peroxide
Keywords: ESR, ultra-fine structure, oxides of terbium and presidium, a stable radical, styrene, phenyloxirane.
Abstract. One of the promising directions in catalysis is the use of heteropolysation (HPS) as oxide precursors, which are complex inorganic compounds formed by Mo and W atoms in the ligand environment and heteroatoms serving as complexing agents.Currently, a wide application in the industry for the oxidation of olefins, production of epoxides, alcohols, acetals are heteropoly compounds (HPC) of various structural types and new formations with high catalytic activity, such as HPS, replaced by rare earth elements (REE). However, using various methods (inhibitors, EPR) it is shown that such catalytic systems play the role of radical initiators. The latter pass from the surface of the catalyst to the volume of the liquid phase, where the oxidation products are formed by a radical chain mechanism.The role of the surface of catalysts in liquid-phase oxidation of hydrocarbons is reduced mainly to the generation of radicals, initiators of the chain process occurring in the volume. In this regard, EPR, more than another method of research, helps to clarify the laws of the formation of
intermediate forms (complexes, radicals) and the final products of the reaction. By EPR spectroscopy of the studied paramagnetic nature of polyoxo tungsten catalysts synthesized on the basis of dodeka ammonium, activated by oxides of terbium and presidium. In oxides of terbium and presidium the catalyst spectra there is an
ultra-fine structure of the lines ESR. It is found that different EPR lines are observed in the EPR spectra depending on the ratio Tb4O7-x and Pr6О11-xand polyoxovolfram. It is shown thattheincrease in the contentof(NH4)10W12O41.H2O with respect toTb4O7-x and Pr6О11-xleads tothe formation of a stable radical(.Hbsh=5mTl, g=1.92). The synthesized catalyticsystem is used fortheepoxidation ofthe dodecene byhydrogen peroxidein the presence of H2C2О4. The maximumyield of epoxy at atemperature of 70-80°C with areaction time of 3-4 hoursis 75-82% on the converted dodecene.

Neplatinal catalysts for riformingprocess
Keywords: catalyticreforming, hydrocarbon composition, neplatinal catalysts.
Abstract. Catalytic reforming is one of the significantprocesses for obtainingmarketable gasoline. Depending on thesystem, type, purpose and application of the catalyst, thecatalytic reforming process, as wellas the yield and quality of the products vary widely.There is a wide variety of reforming catalysts, differing inshape,size and structure. Despite the use of highly effective promoters that have reducedthe content ofplatinum and simultaneously improve the performanceof the catalysts, none of the non-platinum reformingcatalysts that would provide the same large yields of products with high octane numbers are still unknown. The high cost of platinum-containing catalysts determines the need tosearchfor new catalysts that could compete intheir properties with known ones. In the course of the study, the efficiency of various catalysts was analyzedduring the process. theresultsofthestudy showed thepossibility of using non-platinum catalysts under milderconditions, without compromising the selectivity of the dehydrogenation process characteristic of catalyticreforming. One ofthe reasons forthe loss of catalytic activity ofthe catalyst is the deposition of the carbonaceous materialin the porous structure ofthe catalystas a result of its use.Typically, the carboncontent ofthe spent catalyst isin the range of 1% by weight. up to 20% by weight. Even a sufficiently small amount of carbon significantlyreduces the activity ofthe catalyst.The activity ofthe catalyst decreases if the sulfur content in it exceeds 0.1%.
A further task is to study and investigate non-platinumcatalysts in order to optimize the process ofcatalytic reforming.

Specification of PJSC «Avtodizel» motor oils for transport diesel engines with high environmental performance
Keywords: motor oils, diesel engine, ecological index.
Abstract. The article provides information about the technical requirements of PJSC «Avtodizel» for motor oils for diesel transport engines of environmental classes 4, 5, 6. Oil requirements determine the required level of physico-chemical and performance indicators of oils based on the results of laboratory and bench tests. Laboratory tests measure the number of traditional physico-chemical parameters which are included in passports of quality oils (base number, sulphated ash content, volatility, corrosion on the plates of lead and copper, the content of zinc and phosphorus, etc.).In addition, using the original laboratory methods, the temperature of the beginning of lacing is estimated; hydrolytic stability; the ability of oil to hold the soot in suspension finely-divided condition; thermal and mechanical degradation of the thickening additive, etc. The in formativeness of laboratory methods and a certain relationship of some parameters with the aging processes of oils in engines and contamination of their parts by carbon deposits. The features of the aging process of oils in diesel engines of different models of YaMZ are considered. The results of the effect of exhaust gas recirculation on the intake (EGR) to increase oil aging, contamination of parts are presented. It is shown that to the greatest extent the EGR increases the response of the neutralizing properties of the oil to a greater extent than the forcing of the engine by the average effective pressure. The list of indicators by which the level of operational properties of oils is estimated at bench tests in engines (wear of cylinders, piston rings, bearings of a crankshaft; polishing of cylinders; pollution by carbon deposits of the and
piston groove; increase in an oil consumption on waste; stability of preservation of technical and economic parameters of operation of the engine after tests) is given. During bench tests, physical and chemical analysis of samples of the working oil is carried out to determine the change in anti-wear, detergent, anti-corrosive properties of the oil, colloidal stability. The influence of filters- neutralizer for exhaust gases and particulate filters on the properties of the used oils is considered. For engines
of ecological class 6 with filters-neutralizers of the closed type (DPF) oils on the Low SAPS technology with size of sulphate ash content no more than 1,0% are recommended; with the content of sulfur and phosphorus no more respectively 0,4and 0,08%. Approximate compliance of the level of operational properties of oils for engines with various environmental parameters according to the specification is given PJSC «Avtodizel» (RD 37.319.034-17) known standards: STO AAI 003-05, GOST 17479.1-85 and the American petroleum Institute (API) oil classification.

Temperature performance parameters of motor oils
Keywords: evaporability, optical density and coefficient of thermo-oxidative stability of motor oils, methods of monitoring the performance of motor oils.
Abstract. A method is proposed to control the additional temperature parameters of the partially synthetic synthetic engine oil “Lukoil Super 10W-40 SG / CD”, including determining the temperatures of the onset of oxidation, evaporation and temperature transformations, the critical temperatures of these processes. It is shown that for comparing lubricants of a single purpose, it is necessary to take constant values of the test time and thermo-oxidative stability indicators expressing optical density, evaporation and thermal-oxidative stability coefficient. These studies are aimed at expanding information about the temperature parameters of the performance of lubricants. For the study selected all-season, universal partially synthetic engine oil “Lukoil Super 10W-40 SG / CD”. As the means of control and testing, the following were chosen: instruments for thermostating the oils, a photometric device and electronic scales. The research method was as follows. A sample of constant-weight oil 100g was poured into a glass beaker for temperature control and tested sequentially at three temperatures of 180, 170 and 160° C with stirring with a glass stirrer with a rotation speed of 300 rpm for a constant time of 8 hours. The resource of lubricating oils depends mainly on the temperature on the friction surface, which accelerates oxidation processes, temperature decomposition and chemical reactions of metals with oxidation products and additives. In this regard, it is important for designers and technologists to
know the temperatures at which these processes begin and the critical temperatures at which abnormal phenomena occur. Therefore, the purpose of these studies is to test the method of control to determine these temperatures. On the basis of the conducted studies, it has been shown that the application of the proposed method for monitoring the temperature limits of the performance of motor oils provides additional information
on the temperature regimes of their use and improves the classification system.

Peculiarities of application of modern physico-chemical methods of laboratory investigation of oil bitumes and bitumen mixtures (in customs laboratories)
Keywords: petroleum bitumen, bitumen mixture, polymer-bitumen road binders (PBRB).
Abstract. Composite materials, including petroleum bitumen — bitumen mixtures, modified bitumen, are appearing more and more often on domestic and world markets. When speaking of «bitumen mixtures, modified bitumens,» it should be understood that bitumen products of different composition and purpose fall under this definition. Active expansion of Russia’s foreign economic activity, as well as the status of the country as a country with a significant potential in the production of oil products, all contribute to a more active export from the country and import of petrochemical products into it. Export of oil bitumen and bitumen products takes a rather high line in a number of exported goods. At the same time, the difference in the rates of export duties on goods is a frequent cause of cases of inauthentic declaring of goods by dishonest sellers for «leaving» from payment of customs duties. This fact is due to the investigation of bitumen mixtures in customs laboratories. The task of determining polymeric modifiers in bitumen mixtures is especially urgent. Petroleum bitumen, modified with a polymer, as an object of research, is of interest not only to employees of customs laboratories. The questions of the composition of such mixtures, the nature of the changes in their
properties are interesting and are considered in many scientific works. Most of the scientific work is devoted to the study of physical (so-called «commercial» indicators) properties of bitumen products based on petroleum bitumen modified with a polymer. But the introduction of new technologies for processing petroleum raw materials and production of petroleum products, complicating the composition of polymer-bitumen
compositions and expanding the range of such products makes it necessary and urgent to determine the quality and quantity composition of bitumen mixtures. In this paper, we propose some practical algorithm for physical and chemical research that allows us to investigate as completely as possible the chemical composition of the bituminous product and its properties: determine the type and type of filler or modifier, evaluate the nature of the components of the mixture, their number and significance. It is assumed that the methodology of the integrated study of bituminous binders given
in the algorithm will probably be used not only for solving tasks related to the activities of customs laboratories (identification) but also for research aimed at solving the problems of a scientific plan for determining the qualitative and quantitative composition of bitumen mixtures, their structure and composition.
