| Description |
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. |
