| Аннотация: | The pairs of the isometamorphic Donetsk coking (~83-88 % Cdaf) and non-coking (~76-79 % Cdaf) coals
formed under reductive (RC) and less reductive conditions (LRC) have been studied. A comparative study of extracts
and thermal destruction process of RC and LRC has been carried out. The yield and composition of soluble fractions
of coal organic matter was characterized by liquid chromatography and Gas-Chromatography-Mass-Spectrometry
(GC-MS) methods. Obtained results show significant differences in the yield and composition of the hydrocarbons
for the coking and non-coking coals. The relationship between the hydrocarbon composition of coals and their depositional
environment was described. The chemical characteristics of coals deposited under different redox were outlined.
It is established that the yield of alkylated biphenyls correlates with the important technological characteristic
of coals such as yield of semi coking liquid products. |
