Bulursk anthracite from the Omsukchan Basin is comprehensively analyzed. A new method of pneumatic separation of anthracite is proposed, yielding a concentrate of ash content 6–8%. Samples of the concentrate are analyzed. By up-to-date methods, the composition, petrographic characteristics,...
Ozone may be used to accelerate the oxidation of coal and hence to permit more rapid determination of its susceptibility to self-heating and self-ignition. In the present research, the coal is oxidized at 25°C, with low ozone concentrations (~10 mg/L), so as to moderate the destructive effect of...
With a view to comprehensive processing of coal and its ash and slag wastes, the metallogenic specialization of Kuznetsk Basin coal is assessed for different geological and economic regions and for coal of different metamorphic stages. The content of nonferrous and rare metals in Kuznetsk Basin...
At PAO Koks, an organic additive is produced by the thermal solution of coal in the laboratory. Its influence on the quality of metallurgical coke is investigated. The additive is produced from G coal concentrate, using the anthracene fraction of coal tar as the solvent. On introducing 5–10% of...
The microstructure of special coke produced from Shubarkol long-flame coal by thermal oxidation is analyzed. Images of fractures are presented, and the reasons for pore formation are outlined. The structure of the carbon-bearing reducing agent after repeated heating in electrothermal smelting is...
The emission of benzo[a]pyrene is studied when coal tar pitch with different softening temperature is carbonized in the range 350–850°C. The softening temperature of the pitch is not a useful factor in assessing the benzo[a]pyrene emission on carbonization.
The interaction of various classes of organic compounds with the surface of Kuznetsk Basin gas coals is studied. The interaction of organic molecules with the coal surface is analyzed on the basis of chemical, physicochemical, and quantum chemical characteristics. Analysis of the chemical and...
