“…The mineral part of the Ekibastuz coal also contains clay minerals of the composition of kaolinite Al 2 Si 2 O 3 (OH) 4 , quartz α-SiO 2 , and carbonate CaCO 3 [ 12 ]. In [ 31 , 32 ], magnetite was found as an impurity in coal, but the traces of this mineral were not found in this work.…”

Nuclear gamma-resonance spectroscopy on 57Fe nuclei, X-ray diffraction, and scanning electron microscopy have been used to study the narrow fractions of fly ash formed after combustion of the Ekibastuz coal. Two groups of samples of magnetic (ferrospheres) and non-magnetic type have been separated by granulometric and magnetic separation. A number of regularities associated with the granules size of fly ash have been established. According to the data of Mössbauer spectroscopy, a decrease in the magnetically ordered contribution has been identified with the growth of the particle size. After magnetic separation, iron in ferrospheres was found mainly in the structure of Fe3O4/γ-Fe2O3 and α-Fe2O3. The dominant phase was Fe3O4 (60–77%), the amount of which decreases with the growth of the grain size. With the growth of the particle size, the ratio of [Fe]tetra/[Fe]octa positions occupancy in Fe3O4 approaches 0.5; the structure of magnetite tends to the stoichiometric composition. α-Fe was found in the composition of ferrospheres, and a mechanism of its formation was proposed. The main components of the non-magnetic fractions of fly ash are mullite, hercynite, and silicate glass.

“…However, to date, due to the low efficiency, high cost and, paradoxically, energy consumption, the processes of manufacturing generating equipment, as well as due to the disinterest of industrial energy consumers in financing the process of switching to other types of fuel and energy sources, the primary alternative energy source for oil production, according to experts, coal will remain [1]. A powerful argument in its favor is the presence of developed infrastructure for its production, transportation, and processing, the availability of a resource base with a convenient geographical location, as well as a formed economic niche that has already won its sales sector from oil production and refining [2].…”

“…In particular, in order to reduce the energy dependence of the Republic of Kyrgyzstan on gas and oil fuels, the prospects for integrated development and environmental problems of processing brown coal in the Kavak basin using underground gasification of coal, production of water-coal fuel, and lowtemperature pyrolysis are considered, which would make it possible to obtain such commercial products from coal as water-coal fuel, power gas and synthesis gas, as well as synthetic liquid fuel [6]. To assess the suitability of coal for destructive treatment and increase the efficiency of the process, the dependences of the coal's reactivity characteristics on petrographic composition, the coalification stage, the oxidation-reduction degree, and the concentration and composition of the mineral components are determined [7].…”

New methods of processing bituminous and brown coal in synthetic and coal-water fuel production are now gaining relevance. On the one hand, this is dictated by the pragmatic need to reduce the dependence of industrial energy consumers on the prices and quality of hydrocarbon raw materials, especially in the context of the constant exacerbation of market restrictions associated with the pandemic and sanctions, on the other hand, there is an urgent need for environmentally friendly methods of using synthetic and coal-water fuels. The article discusses the currently used technologies for the production of synthetic and coal-water fuels. The authors identify its main disadvantages and limitations and propose a schematic diagram of a technological line for coal-water fuel production with a linear layout. It allows obtaining fuel with good fluidity and higher stability, high-calorie content, and low ash content with less energy consumption.
