- Abstract
Russia, China and, Mongolia are among the countries having large reserves of coals which are traditionally utilized mainly as a fuel for energy generation. In the present paper, the solvolysis of a large series of different-ranked coals from various deposits of Russia and Mongolia in anthracene oil as a solvent to produce soluble aromatic substances was studied. All the coal samples were well characterized by the data on the chemical composition and on the conventional classification industrial indexes. The correlations between the composition and properties of coals and their reactivity for pyrolysis and for solvolysis with anthracene oil into soluble products were analyzed. Well defined correlations were established between the coal conversion into quinoline solubles and the properties of coals such as vitrinite reflectance, the yield of volatile matter, carbon content, and temperature at which the main decomposition occurs during coal pyrolysis. The criteria for the properties of coals suitable for solvolytic conversion into soluble aromatic substances are suggested. The chemical and group composition and the characteristics of the molecular structure of the soluble products obtained were studied using chemical and 1H and 13C NMR techniques. The extract obtained can serve as an alternative source for aromatics, liquid fuels, and for the production of a substitute for coal-tar pitch binder and for other purposes.
