In order to optimize the performance of transportation works for the transportation of raw materials for the production of biodiesel fuel, the article examines the technology when oil from oilseeds is obtained at the processing points where they are grown. The resulting oil is transported to a biodiesel production plant. The methodological bases for calculating the optimum distance from oilseed grain storage sites to a mechanized oil production point are presented. Possible ways of the efficiency improving of production of biofuel at the stage of the planning are presented. Methodical bases of calculation of distance to mechanized points for biofuel production are given. A formula for determining the optimum capacity of an item for the processing of oil seeds and for obtaining raw materials for the production of biofuels has been derived. It is established that optimum transportation distance of rape is 14,4 km, productivity of the rapeseed oil processing plant is 21280 tons/year and for 25% of the oil yield 5320 tons of biofuel raw materials can be obtained, when the total overhead costs are Zv = 360000 UAH / year; specific costs of transportation of raw materials сp = 2,6 UAH/ (тkm); yield of oilseed rape = 1 t / ha (100 t / km2); the density of the placement of fields a = 0.4. The developed method can be used to calculate the location, performance of points for the manufacture of briquettes or pellets. The direction of increasing the efficiency of biodiesel production at plants at the stage of their planning is to determine the optimal annual productivity of the plant, taking into account transport costs for the transportation of raw materials - oil. The optimum distance of transportation of oil and productivity of the plant for biodiesel production is established for the cost of transportation - 2.6 UAH / t • km, overhead costs 13000000 UAH, direct costs for the production of 1 ton of biodiesel fuel - 25000 UAH Therefore, the optimal distance of transportation of oil for the production of biofuels - 101 km, the capacity of the plant - 58923 tons. The dependence of the cost of production of biodiesel fuel on the distance of transportation of oil is calculated: for distance to plant 40 km – the cost of biofuel production – 25596 UAH/t, for 60 km – 25496 UAH /t, for 80 km – 25462 UAH /t, for 100 km – 25459 UAH /t, for 120 km – 25471 UAH /t, for 140 km – 25493 UAH /t. The proposed method provides an opportunity to determine the optimum productivity of the plant for the processing of organic raw materials into biofuels, taking into account the distance of its transportation at the design stage. Key words: biodiesel, economic efficiency, production optimization, direct costs, overhead costs.

Increasing concentrations of greenhouse gases in the atmosphere are leading to increased production and use of biofuels. The industrial development of biodiesel production and the use of biodiesel in the EU transport sector have been ongoing for almost two decades. Compared to mineral diesel production, the process of producing biodiesel is quite complex and expensive, and the search for new raw materials and advanced technologies is needed to maintain production value and expand the industrial production of biodiesel. The purpose of this article is to review the application possibilities of one of the new technologies—simultaneous extraction of oil from oily feedstock and transesterification (in situ)—and to evaluate the effectiveness of the abovementioned process under various conditions.

Biodiesel Synthesis

Abstract The ever-increasing environmental pollution from greenhouse gases motivates the search for methods to reduce it. One such method is the use of biodiesel fuels in the transport sector. Conventional biodiesel production generates up to 10% of a by-product, raw glycerol, whose amount continues to increase as biodiesel production volumes expand, but its demand remains limited. Recently, options have been analysed to replace the triglyceride transesterification process generally used in biodiesel production with an interesterification process that does not generate raw glycerol, instead yielding triacylglycerol that can be directly used as fuel for diesel engines by mixing with fatty acid esters. Additionally, triacylglycerol improves the low-temperature properties of fuel. The present article discusses triglyceride interesterification processes using various carboxylate esters of low molecular weight. Information is provided on raw materials that can be subjected to interesterification for biodiesel synthesis. The possible applications of chemical and enzymatic catalysis for triglyceride interesterification are discussed, and the influence of the catalyst amount, molar ratio of reactants, temperature and process duration on the effectiveness of interesterification is examined. The conditions and effectiveness of noncatalytic interesterification are also discussed in the article. Qualitative indicators of the products obtained and their conformity to the requirements of the European standard for biodiesel fuel are discussed.

Biofuel is one of alternative fossil fuel, in which the raw materials come from biological resources.One of the raw materials for biofuel production is microalgae. Microalgae grows rapidly, does notcompete with food for humans, and needs small areas to cultivate. Utilization of microalgae forbiofuel research nowadays is focusing on biodiesel production, but actually microalgae can beused to produce other biofuels such as bioethanol. The carbohydrate content of the microalgaecan be converted into glucose and fermented into alcohol. Carbohydrate content of the microalgaeis about 5.0–67.9%, which could produce bioethanol up to 38%. A harmony between bioethanoland biodiesel production from microalgae is needed for the optimum utilization of microalgae.Bioethanol production from microalgae can be done using de-oiled microalgae.

The waste cooking oil is transfered into biodiesel by using potassium hydroxide (KOH), alcohol (methanol) at a set temperature and time. The concentration of catalyst should be at correct level or else it will lead to negative effect on the overall output of the biodiesel produced. The biodiesel conversion is done to remove the free fatty acids present in the vegetable oil using transesterification process. It is known that the boiling point of methanol is 67 °C it gets evaporated if the reaction temperature exceeds beyond the boiling point. Due to evaporation the methanol required for the reaction to proceed forward may not available. Thus inorder the save lose of methanol due to evaporation during high temperature operations, a condenser is required to condense the escaping methanol in the form vapour. This condensed methanol is again sent back to the reaction vessel to carry the transesterification reaction. Petroleum diesel is widely used in the automobile sectors, industry purpose, domestic uses and in agriculture for generation of power (mechanical) energy for the purpose of meeting the energy demands. The fuels from alternate sources are renewable and does not cause severe effect on the environment. Biodiesel is one such source of fuel which can greatly support to reduce the dependency on conventional fuels. It will complete process in 1 to 2 days to finish the vegetable oil into biodiesel fuel. Biodiesel is renewable energy source to be produce the natural oil and also fats. Hence producing biodiesel is will be a better way to compensate the energy demands and the cost involved during production should also be considered. One of the cost reducing method is saving the raw materials from wastage.

Haphazard mining and consumption of fossil fuels have reduced petroleum reserves causing fossil fuel depletion and environmental degradation; thus, reflecting the need of the cheaper, renewable and eco-friendly alternative source of petroleum to meet the fuel demand. Million liters of edible oil used for cooking foods and date expired oils from oil manufacturers are discarded into sewage. This study primarily intends to study the feasibility of biodiesel production using such waste oils. In this work, biodiesel was prepared from waste cooking oils by a process called transesterification with NaOH as a catalyst. Our results showed that methyl ester (biodiesel) (92.67±0.90%), soap materials (1.33±0.224%) and glycerol (6±0.68%) were obtained after the transesterification of waste cooking oil. The physicochemical properties of biodiesel such as density, viscosity, volatility, surface tension and flashpoint were analyzed, which were found to be 0.862±0.006 g/cm3, 2.23±0.021 cP, 0.327×10-3±4.5×10-6 g/s, 32.03±0.138 dyne/cm, 169.67±0.810°C, respectively. These properties were compared with that of commercial diesel as well as with the values specified by the American Society for Testing and Materials (ASTM) D6751. The density and the surface tension of the biodiesel were found similar to that of petrodiesel but its volatility was 3 times lower. Fourier-transform infrared spectroscopy (FTIR) spectra of the biodiesel showed methyl ester functional group at 1436 cm-1. Based on the cost of the materials used for production, the cost of biodiesel was estimated to be about 81 Nepalese rupees (0.67 USD) per liter. The properties of biodiesel also met the standard values of ASTM D6751. These findings indicate that waste oil is one of the feasible biodiesel sources and it can be used as a suitable alternative to petrodiesel.

Abstract Soybeans have become widespread in the world crop production as a valuable oilseed and high-protein crop with a unique biochemical composition. In the Russia in 2015-2019 annually there is an increase in acreage, yield and gross yield of soybeans. The research purpose is to substantiate the most effective system of basic soil cultivation during the soybeans cultivation in the Samara region. The research tasks included: to study the peculiarities of the soybeans yield formation depending on the main tillage systems, to evaluate the economic efficiency of the main tillage systems. It was found that the basic tillage system provided the best conditions for the formation of the soybean in 2018-2019. Thus, the highest yield was obtained in the variant with plowing by 20-22 cm and amounted to 14.9 cwt/ha, the lowest in the variant without autumn mechanical tillage - 10.1 cwt/ha. The calculation showed that the soybeans cultivation in all variants was effective. Direct costs in the soybeans cultivation varied according to the studied options from 15879.28 rubles/ha to 17767.34 rubles/ha, the cost price - from 1192.4 rubles/cwt to 1572.2 rubles/cwt. The basic tillage system with elements of minimization reduced direct costs, however, due to the lower yield, the highest net income was obtained in the variant with plowing by 20-22 cm and amounted to 19482.7 rubles/ha, with a profitability of 109.7%.
