It is known that one of the ways to increase the level of operational properties of diesel fuels is the injection of special components – additives – into their composition. Today this way is a quite rational and economically feasible for Ukraine, especially in the absence of high-quality oil raw materials for the production of fuels, which in turn leads to a significant dependence on imports. The range of additives used in diesel fuels is very diverse, which makes it difficult to select a balanced package, especially considering their effectiveness and compatibility with each other. This procedure can be a bit simplified by adding poly-functional additives to diesel fuel, the use of which is devoted to a lot of periodical literature. Based on the relevance of the direction of scientific research related to improving the properties of diesel fuel, which is produced at the enterprises of the oil refining industry in Ukraine, we proposed to use a substance belonging to the class of aromatic diazocompounds and having polyfunctional properties in the composition of diesel fuels. Thus, this additive was added to a straight-run diesel fraction (240–350 °C) in an amount of up to 1.0%, followed by a study of the properties of the resulting mixture. Studies have shown that the additive significantly improves low-temperature properties (by -10 °C), contributes to an increase in fuel density and viscosity, and additionally gives diesel fuel a stable color (from yellow to orange). Consequently, it can be used in the composition of commercial diesel fuels with improved performance properties.

The n-tetradecylacrylate-vinyl acetate copolymer (PPV) was prepared from n-tetradecylacrylate and vinyl acetate. The PPV was employed as pour point depressant to improve the low-temperature fluidity of the -20# diesel from Daqing Petrochemical Company. The result indicated that the solidification (SP) and the cold filter plugging point (CFPP) were affected largely by PPV. And when mass fraction of PPV -14(copolymerization conditions: 80 °C,w（benzoyl peroxide）1％（total weight of raw materials）, n（vinyl acetate）∶n（n- tetradecanolacrylate） = 4∶1 ) in diesel fuel was 0.1%wt, the SP reduced by 15.0 °C, the CFPP reduced by 6.0 °C simultaneously; We analysise the different molecular weight of PPV-14, and discover that the molecular weight of PPV-14 is ralated to the the low-temperature fluidity of the -20# diesel from Daqing Petrochemical Company. When mass fraction of PPV -14(molecular weight is 15000, distribution coefficient is 3.11) in diesel fuel was 0.1% wt, the SP reduced by 18.0 °C, the CFPP reduced by 7.0 °C, simultaneously.

Lubricating Properties

The paper reviews the structural and group composition of three basic winter diesel fuels and its influence on the low-temperature and lubricating properties of fuels. It is shown that a high content of saturated hydrocarbons, primarily medium-molecular n-alkanes, and arenes with a higher proportion of substitution leads to a deterioration of low-temperature properties. A decrease in the proportion of medium-molecular alkanes and even a slight increase in the content of bi - and polycyclic aromatic hydrocarbons impairs the lubricating properties of the fuel.The influence of the component composition of diesel fuels on the effectiveness of anti-wear and depressor-dispersing additives was noted. The study of compatibility of additives of different functional actions revealed that the anti-wear additive based on fatty acids of tallow oil does not affect the activity of the depressant-dispersing additive, while the combined use of these additives slightly worsens the lubricating properties, but does not lead this indicator beyond the established standards.

Hydrotreated Diesel

The researches related to the development of the best composition and production of environmentally friendly diesel fuel, compliance with the EURO-5 and EURO-6 class, by introducing antiwear additives into the base hydrotreated fuel were conducted. The analysis of modern assumptions to the use in Russia of anti-wear additives of domestic and foreign manufacturers, such manufacturers as Clariant, BASF, Infinéum, JSC "AZKiOС" and others was carried out, and also the main results of efficiency of use of additives for diesel fuel are considered. The synthesis of antiwear additives and antioxidant additives from plant raw materials through the process of transesterification was carried out, as well as the technology of obtaining nitrogen and oxygen-containing compounds with surface active properties was developed. The optimal technological processes of the transesterification process (time, temperature, rate, ratio of raw materials) were revealed. The effect of the obtained bioadditives on the operational and low-temperature properties of hydrotreated diesel fuel was studied. Analysis of the positive effect of additives on lubricating properties of fuel showed that the diameter of the wear spot is reduced by a factor of 4, the amount of harmful emissions (carbon oxides, dispersed particles, volatile organic compounds and hydrocarbons) is reduced by more than 30 times. Also, a decrease in the pour point and change in the cetane number was observed, depending on the composition of the bioadditives (in some cases, the cetane number decreased and ceased to meet the requirements of the standard for diesel fuel GOST R 52368, while others, on the contrary, increased). A distinctive feature of this type of fuel is the maintenance of the minimum amount of gray in your composition, and at the same time compliance with all requirements of GOST.

The time and emissions during cold starting were investigated at cold and hot temperatures (i. e., – 10°C, 0 °C, 25°C and 50 °C). The effect of injection timing (IT) on these factors was also studied at four ITs before top dead centre (BTDC) i. e., (12 , 15 , 20 and 23 BTDC). The results were compared with engine operation at 17 BTDC (factory IT). Sunflower vegetable oil and yellow grease were used as raw materials to prepare bio diesel fuels through transesterification. B20 (20% sunflower oil biodiesel+80% diesel) and W20 (20% yellow grease biodiesel+80% diesel), together with neat conventional Iraqi diesel fuel, were used to analyse engine startability and emissions under cold and hot starting conditions. Results indicated that adding biofuel affects the engine starting response and that the starting time stabilises at high starting temperatures. At a low starting temperature (i. e.,–10 °C), hydrocarbon (HC) and carbon monoxide (CO) concentrations increase significantly. At moderate and high starting temperatures, the oxygen content in the biofuel blend plays a dominant role in reducing the HC and CO concentrations. Smoke opacity has increased notably for the biodiesel blends at low starting temperatures but has decreased significantly at moderate and high starting temperatures. Both biofuel blends emit higher levels of nitrogen oxide than the neat diesel fuel. Noise increases at low starting temperatures, thereby indicating rough combustion.

Abstract The aim of the research is the development of theoretical and methodical bases for determining the feasibility of plant raw materials growing for its further bioconversion into energy resources and technological materials to maximize profit from business activities. Monograph, statistics, modelling and abstract logical methods have been used during the research. Directions of biogas usage have been examined. Biogas yields from different crops have been analyzed. It has been determined that high methane yields can be provided from root crops, grain crops, and several green forage plants. So, forage beet and maize can provide more than 5,500 m3 of biogas per hectare. Attention is paid to the use of by-products of biogas plants, especially carbon dioxide. Carbon dioxide is an important commodity and can increase profitability of biogas plant operating. It can be used for different purposes (food industry, chemical industry, medicine, fumigation, etc). The most important parameters of the biogas upgrading technologies have been analyzed. If output of an upgrade module is more than 500 nm3/h, investment costs of different available technologies are almost equal. According to experts, it is economically feasible to use anaerobic digestion biogas systems to upgrade biomethane provided their performance is equivalent to 3,000 litres of diesel fuel per day. The economic and mathematical models have been suggested to determine the feasibility of growing plant materials to maximize the gross profit. The target function is the maximum gross income from biogas utilization. It has the following limitations: annual production of biogas, consumption of electricity, heat and motor fuels. The mathematical model takes into account both meeting own requirement and selling surplus energy resources and co-products including carbon dioxide. In case of diesel fuel substitution, an ignition dose of diesel fuels has been considered. The algorithm for making a decision on construction of a biogas plant has been offered.

Natural bitumen refers to unconventional sources of hydrocarbon raw materials, the development of which is one of the most important urgent tasks in oil refining. Along with the development of new deposits, problems arise with transportation and processing. To solve these problems, extraction deasphalting is proposed, which allows the use of natural bitumen to transport natural bitumen to refineries without the use of additional diluents. The main focus of the extraction approach is the production of low-viscosity deasphalted oil and high-quality road bitumen.

The Mathematical Model

The authors reviewed the statistics of winter diesel fuel consumption in the Russian Federation for 2000–2017, revealed a positive growth rate. On this fact, the relevance of the study was substantiated. The complexity and importance of the refining process leads to the need for digitalization of oil refineries. The object of the study is obtaining winter diesel fuel, taking into account transport costs. The subject of the study is digitalization of the oil refining process on the base of constructing the mathematical model for obtaining winter diesel fuel, taking into account delivery costs. Main research methods: retrospective data analysis, synthesis, comparison, linear programming methods. The authors considered two stages of winter diesel fuel production: dewaxing a mixture of stages of hydrocarbon raw materials on zeolite and subsequent compounding. For each stage, the authors compiled a system of equations describing the process. The authors also compiled a target function for obtaining winter diesel fuel, taking into account the costs of receiving and delivering. The obtained mathematical model can be used to ensure the required quality of winter diesel fuel (in terms of sulfur content, density and flash point).
