Production of Biocoal by the Pyrolysis of BiomassAllerton Press - Tập 53 - Trang 369-376 - 2020
A. Yu. Krylova, E. G. Gorlov, A. V. Shumovskii
Effective use of biomass has recently received special attention. Pyrolysis is of great interest among the biomass conversion processes. The pyrolysis technology allows the production of biocoal (biochar), which can replace fossil energy fuels. Biocoal can also be converted into liquid fuel for direct use in vehicles and for the replacement of petroleum products (gasoline, aviation kerosene, and d...... hiện toàn bộ
Cytological structures in the macerals of fossil coalsAllerton Press - Tập 49 - Trang 54-57 - 2015
L. Ya. Kizil’shtein, A. L. Shpitsgluz
The cells of fossil plants, which can be observed with the aid of a light microscope, are described in this work. The samples of fossil coals—anthracites in polished sections subjected to ion etching—were studied.
Reclamation of soil polluted by gas condensate using peat compostAllerton Press - Tập 48 - Trang 320-322 - 2014
R. V. Galiulin, R. A. Galiulina, V. N. Bashkin
An approach to the reclamation (the recovery of fertility) of soil polluted by gas condensate in the territory of a boosting compressor station using peat compost was developed. The efficiency of soil reclamation was evaluated by an analysis of catalase and dehydrogenase enzyme activities and by the sowing and cultivation of perennial grasses in the area.
Analysis of the Physical and Chemical Properties of Fat Coal at Different Pyrolysis Temperatures in UCG EnvironmentAllerton Press - - 2022
Fu, Xiaojin, Li, Kaixuan, Xin, Lin, Feng, Mingze, Wu, Jing, Li, Jiaze, Wang, Zhigang
To explore the physicochemical properties of fat coal at different pyrolysis temperatures in UCG environment. In this study, aiming at the temperature variation range in the process of UCG reaction, the pyrolysis experiments of fat coal in Tianjin Qianjiaying Coal Mine at 200, 400, 600, 800 and 1000°C were carried out by using a high-temperature tubular pyrolysis furnace. XRD and FTIR analyzed the...... hiện toàn bộ
Solid fuel quality control by the pulsed neutron–gamma methodAllerton Press - Tập 51 - Trang 183-187 - 2017
Yu. N. Pak, D. Yu. Pak
The possibility of controlling the ash content of fuel based on a carbon/oxygen ratio taking into account variable carbon content out of the organic matter was demonstrated. An algorithm was proposed for the determination of the ash content with the use of a pulsed neutron method with the detection of gamma rays from inelastic neutron scattering on the nuclei of carbon, oxygen, and calcium with an...... hiện toàn bộ
The degree of reduction problem in structural-chemical classification of coalsAllerton Press - Tập 41 - Trang 79-84 - 2007
A. M. Gyul’maliev, S. G. Gagarin
A parameter (B, %) that characterizes the extent of chemical reduction of the carbon skeleton of arbitrary organic entities containing C, H, N, O, and S atoms is proposed for quantitative description of coals of different genetic types in terms of the degree of reduction in the framework of the structural-chemical classification of fossil fuels. According to the values of B, the groups of coal mac...... hiện toàn bộ
Variation of Sulfur Content in Coking Coal as Function of Its Particle SizeAllerton Press - Tập 54 - Trang 326-336 - 2020
X. G. Mu, Z. X. Jin, C. B. Deng, F. Gao
To understand quality of coking coal possessing different particle sizes, coal samples from Gao Yang (GY) and Shui Yu (SY) mines were systematically studied. The samples had wide particle size variations with six distinct ranges. The main emphasis was placed on analyzing sulfur and coke contents as function of particle sizes. X-ray photoelectron spectroscopy (XPS) was used to analyze sulfur conten...... hiện toàn bộ
