The replacement of State Standard GOST 9318-91 for the determination of coal’s clinkering properties (on the basis of the Roga method) by GOST R ISO 15585-2009 is assessed. It is shown that deficiencies of the ISO method limit the information that may be obtained. It is expedient to determine the clinkering properties of coal by the Roga method on the basis of the ISO 335:1974 standard. © 2014, Allerton Press, Inc.

Industrial methods are proposed for the heat treatment of B, A, SS, and T coal with poor (if any) clinkering properties; the characteristics of the solid products (coke, semicoke) are presented. By preliminary heat treatment of such coal, solid products suitable for various industrial uses may be obtained. © 2013 Allerton Press, Inc.

The technological value of coal used for coking is analyzed, with particular attention to clinkering coal, the coke group, and lean additives, as well as G and GZhO coal. A relation is established between the technological value of the coal components and their permissible content in coking batch so as to produce coke of constant strength (M 25 = 87%). The precision in determining the technological value of coal is assessed. © 2013 Allerton Press, Inc.

The composition and yield of the products obtained in the underground gasification of coal at Podzemgaz South Abinsk Station are studied. Data are also presented regarding the rectification and hydrocracking of the products. The underground gasification of coal may be regarded as a potential source of phenolic hydrocarbons, naphthalene, pyridine bases, raw materials for the production of carbon black, and hydroaromatic solvents. © 2013 Allerton Press, Inc.

A model is proposed for predicting the coke strength (M40 and M10) and its NSC parameters CSR and CRI on the basis of the chemical and petrographic parameters of the coal. The model takes account of the chemical composition of the ash, the duration of coking, and the coke-slaking technology. On the basis of this model, the technological value of the coal types used at OAO EVRAZ ZSMK is assessed, and the batch composition is optimized to produce coke of elevated quality. © 2013 Allerton Press, Inc.

A distinction is proposed between mineral coal and extracted coal. Mineral coal is a complex natural composite that is found in underground beds, while extracted coal is created from mineral coal in working those beds. It is important to keep in mind that mineral coal is created by natural processes, whereas extracted coal is produced by human activity. © 2013 Allerton Press, Inc.

The structural strength of the coke produced may be predicted on the basis of the coefficients V PM, K GL, K P, K SC, which, in turn, are calculated from measurements of A d, V daf, and y in coal and of A d, V daf, and S s in plastometric semicoke. If the coke yield (K co) is taken into account, those coefficients may be used to determine the coking capacity (K cc) of the coal and to predict the structural strength of the coke body (K ssc) produced from that coal. On the basis of K ssc, coking coal may be divided into two categories: coke-forming coal; and filler. © 2013 Allerton Press, Inc.

The technological value of coal may be determined by predicting the strength and reactivity of the coke produced on the basis of the chemical and petrographic characteristics of the coal and the chemical composition of its ash. © 2015, Allerton Press, Inc.

The development of the polyene model of coal structure at the Eastern Coal-Chemistry Institute (now OAO VUKhIN) between 1975 and 2015 is surveyed. In terms of the polyene model, the vitrinites in coal are amorphous polymers whose monomer component contains cis-polyene chains in helical form and trans-polyene chains in flat zigzag structures, whose skeleton includes not only polyene systems but also methylene groups. The supermolecular structure of the vitrinites is determined by the molecular interactions between the monomers and includes highly ordered double helices, twin flat zigzag structures, and more complex structures, leading to the formation of globules and flat blocks. © 2015, Allerton Press, Inc.
