Several means of spectral correction and sampling are compared in terms of their information content when calibrating coal’s ash content and yield of volatiles.
The thermodynamic characteristics of an organic system are determined. The state factors of the organic system are identified: the partial oxygen pressure, oxygen activity, temperature, and pressure. Functional relations are found between the redox state of the system and the quantitative ratio...
Theoretical and practical aspects of wet slaking that combines pulsed and dual (two-loop) cooling of the coke are outlined. The introduction of the new technology at ZAO Makeevkoks reduces the overall moisture content of blast-furnace coke and improves its uniformity, while reducing atmospheric...
The interaction of low-metamorphic coal components in coking batch during pyrolysis is studied. The characteristics of the resulting coke are presented, and the partial hydrogenation is discussed.
Papers at a Russian conference on problems with the sources, quality, and effective use of carbon materials (including coal, schungite, and petroleum coke) in ore and chemical electrofurnaces are briefly summarized.
A three-dimensional model of the heating wall in a coke battery is developed by means of the Fluent CFD program. The results of simulation are in satisfactory agreement with experimental data. The mathematical model permits the maintenance of more uniform heating over the height, width, and...
The properties of petro/coal tar pitch and distillate fractions obtained in the joint distillation of coal tar and heavy pyrolytic oil from ethylene production are described. The petro/coal tar pitch is particularly reactive in heat treatment and air-blowing. The petro/coal tar pitch may be used...
