Attention focuses here on methods of coal processing that require minimal quantities of water and yield products that may be effectively used as commercial and secondary raw materials. In the heat treatment of coals associated with semicoking, the accompanying physicochemical transformation of...
The chronological development of the IKAP and SPEKTROTEST automated IR analyzers used for express determination of coal quality in production laboratories is described.
The traditional chemical framework for determining the air excess in the heating of coke furnaces is discussed. In determining the air excess, no account is taken of numerous chemical reactions associated with the combustion of the fuel gas in the heating channels. In fact, it is necessary to...
This review covers research at AO Vostochnyi Nauchno–Issledovatel’skii Uglekhimicheskii Institut (VUKhIN) over the past 50 years on the extraction of tar and naphthalene in the primary cooling of coke–oven gas and also on related topics such as the conditioning of coal tar and the cooling of...
The commonest methods of producing carbon nanotubes are analyzed, and the main types of carbon precursors employed in carbon nanostructures are reviewed. Parameters that affect the formation of carbon nanotubes in synthesis are identified.
The use of a drum chute instead of the regular chute is proposed in coke sorting prior to classification. A method of calculating the optimal drum dimensions is outlined. The drum’s inclination is plotted as a function of the required number of drum rotations to which the coke is subjected. A...
