The article is aimed at developing a methodological approach to a consistent and rational choice of promising for the development in Ukraine types of alternative motor fuel and innovative technologies for its production, substantiation of the system of technical and economic indicators of the complex for the production of synthetic motor fuel from the low-grade raw materials. One of the key problems of Ukraine’s energy provision today is its high dependence on the import of finished motor fuel, which can be reduced by the development in the country of alternative types of motor fuel based on the latest technologies. The article, based on the provisions of economic theory, discloses the essence of the developed methodological approach to the consistent choice of promising types of alternative motor fuel for their development in Ukraine and innovative technologies of its production. The developed methodological approach for rational choice of promising for the production in Ukraine and use of motor fuel types includes an evaluation of the following: compliance of consumer properties of certain types of motor fuel with the requirements of the existing motor fleet (target); efficiency of motor fuel production technologies (capabilities); sufficiency of resource provision for the production of motor fuel (restrictions). The methodical approach is brought to the level of the methodology, the use of which allows to identify promising types of alternative motor fuel for use in the country and innovative technologies of their production. Along with the developed methodical approach, the expediency of development in Ukraine of the synthetic motor fuel industry is proved on the basis of using the method of indirect coal liquefaction (according to the Fisher–Tropsch method). The result of the work is a system of technical and economic indicators of the complex for the production of synthetic motor fuel from the low-grade raw materials.

The article presents the results of large-scale laboratory tests carried out in the conditions of the Chemical and Metallurgical Institute named after V.I. Zh. Abishev on the use of briquetted mono-charge in the smelting of carbon ferrochrome on a 250 kVA furnace. The purpose of these studies was to determine the technological parameters of the use of briquetted mono-charge containing in its composition chrome ore, wastes from the production of high-carbon ferrochrome, middlings and various carbonaceous reducing agents. The main idea of using these briquettes was to multiply the contact surface of the reductant and ore, which should speed up the technological process. The principal possibility of smelting a standard alloy using briquetted mono-charge is shown. The alloy for individual charge options meets the requirements of the standards. In comparison with the technology without the use of briquettes, the mono-charge technology has shown advantages in all main parameters. The technology with the use of briquettes from the dust of the AktZF gas cleaning system is distinguished by a low yield of non-standard metal and slag, the bulk of the material goes into the gas collection system. Technologies from briquettes from fines pellet production area of Donskoy ore mining and processing plant and flash have very low specific technical and economic indicators and cannot be recommended for industrial use. Improvement of briquetting modes and technology of their smelting is required. The technical and economic indicators were higher than the current one, showed briquettes from ore and coke of the People's Republic of China, briquettes of ore from borlin and shubarkol coals of Kazakhstan.

Questions of melting of iron ore and raw materials with receipt of cast iron and slag are considered in vitro. The chemical composition of cast iron of slag is studied in vitro. The viscosity of slag is researched. Object of research - titaniferous ores with various contents of titan dioxide. The technical and economic indicators of a blast furnace melting an agglomerate and pellets (a consumption of coke and productivity, a chemical composition of cast iron and slag) received from a concentrate of the Kachkanarsky deposit are calculated. The technique of scientific research is used [1].

Oil flax grows in many countries of the world. Fibre production on its basis can significantly increase the profitability of flax-growing farms. At the present stage, taking into account the real possibilities of the national economy, for its effective development  it is necessary to introduce advanced technologies. Cur-rently, processing enterprises may choose among different technological equipment lines to process oil flax into fibre and thus get additional profit. (Research purpose) The determination of a technologically and economical-ly effective line for oil flax processing. (Materials and methods) The main materials for calculation were represent-ed by the indicators of production capacity, the average annual value of fixed as-sets, the amount of money spent on salaries and wages, etc. The main research method is the balance method that allows making a plan in the form of a balance sheet that takes into account the sources of inputs and the requirements for these inputs. (Results and discussions) The authors have considered low-cost lines for oil flax processing into short fibre on the basis of disintegrators of various brands (from domestic and foreign producers), offered characteristics of the fibre obtained in the lines, and analyzed technical and economic indicators of various technologi-cal lines under different conditions, and the payback period of capital expenditures for different oil flax acreages. (Conclusions) The authors have determined that the most effective is the pro-cessing of oil flax from an area of at least 1000 hectares, with a throughput capaci-ty of raw materials of at least 1000 kg/h and a distance of the transportation of straw rolls to a processing site of 50 km. They have also obtained technological and economic data that can be used in the organization of oil flax processing into marketable fibre.

Variants of the intensification of the solvent dewaxing process, which increase the yield of base oils, are described. One of the promising ways to improve the technical and economic indicators of the dewaxing process is the use of modifying additives. The work shows that the introduction of a polymer additive requires a decrease in the filtration rate and, accordingly, an increase in the performance of the dewaxing unit. This results in a petrolatum with a reduced oil content, which is a qualifying factor for the production of high-melting ceresins, protective-wax components, and lubricants for various purposes.

При выборе типа доильной установки и ее размера необходимо учитывать максимальное планируемое поголовье дойных коров и размер технологической группы, кратность и время одного доения, продолжительность рабочей смены дояров. Анализ технико-экономических показателей наиболее распространенных на сегодняшний день типов доильных установок одинакового технического уровня свидетельствует, что наилучшие удельные показатели имеет установка типа «Карусель» (1), а установка типа «Елочка» (2) требует более высоких затрат труда и средств. Установка «Параллель» (3) занимает промежуточное положение. Из анализа пропускной способности и количества необходимых операторов: установка 2 рекомендована для ферм с поголовьем дойного стада до 600 голов, 3 — не более 1200 дойных коров, 1 — более 1200 дойных коров. «Карусель» — наиболее рациональный, высокопроизводительный, легко автоматизируемый и, следовательно, перспективный способ доения в залах, особенно для крупных молочных ферм. The choice of the proper type and size of milking installations needs to take into account the maximum planned number of dairy cows, the size of a technological group, the number of milkings per day, and the duration of one milking and the operator's working shift. The analysis of technical and economic indicators of currently most common types of milking machines of the same technical level revealed that the Carousel installation had the best specific indicators while the Herringbone installation featured higher labour inputs and cash costs. The Parallel installation was found somewhere in between. In terms of the throughput and the required number of operators Herringbone is recommended for farms with up to 600 dairy cows, Parallel — below 1200 dairy cows, Carousel — above 1200 dairy cows. Carousel was found the most practical, high-performance, easily automated and, therefore, promising milking system for milking parlours, especially on the large-scale dairy farms.
