By statistical analysis of research data for coal samples, coal blends, and coal batches used in Russia and Kazakhstan, relations between the vitrinite reflection coefficient and the fuel ratio are established, with good agreement between the calculated and actual vitrinite reflection...
Low-temperature pyrolysis of slightly metamorphosed D, DG, and G coal in a Fisher retort produces semicoke, whose specific surface, total pore volume, micropore volume, and mesopore volume are determined. The porous structure of the semicoke is investigated at the 77 K isotherm corresponding to...
The change in the physicochemical properties of anthracite on calcination at 400–1600°C is studied. The temperature dependence of anthracite’s electrical resistivity is determined. On that basis, the optimal geometric and electrical parameters of the calcining furnace are calculated. In the...
The corrosive activity of coal-tar wash oils is investigated. An electrochemical method is proposed for assessing the corrosive activity of the oil with respect to carbon steel. The main sources of corrosive impurities in the absorbers are identified. The contamination of the oil is assessed on...
Means of utilizing coke-plant wastes are investigated. Their environmental impact is evaluated. A new method is developed for using heavy coal tars to generate producer gas. The electrical converter employed permits regulation of the gas composition so as to increase the content of flammable...
