Comparison of the coal-bed thickness (M), the gelification characteristic (Vt), and the reducing characteristic (Πr) reveals the influence of the group composition of paleoflora, the landscape, and the types of ancient bog on these factors for Kuznetsk coal.
Coal-batch formulation on the basis of rank is analyzed. The corresponding theory is developed.
The influence of heat treatment (750 and 1000°C) of nonclinkering and poorly clinkering D, G, SS, and T coal on the pore structure and properties of coke is studied. The porosity of coke from coal pieces and crushed coal is significantly different.
The carbonization of low-ash lignite in a fluidized bed at 650–800°C is considered. The dependence of the basic process parameters on the air flow rate, the coal consumption, and the fractional composition of the coal is investigated. The characteristics of lignite coke obtained by the...
Attention focuses on the products and process of liquefaction of Baganursk and Tugrugnursk lignite (Mongolia) and Podmoskovnyi, Kansko-Achinsk, and South Yakutsk lignite (Russia), in the presence of various hydrogen donors (tetralin, mixtures of tetralin with isopropanol, the hydrocarbon...
The hydrothermal treatment of sapropelite is investigated, to establish the distribution of mineral components in the decomposition products. In hydrothermal pyrolysis, an organic-mineral mixture is obtained. The mineral components may be extracted from this mixture. The results suggest that the...
The radioactivity of Kuznetsk Basin coal and ash is considered, in relation to other regions.
