Аннотация: The characteristics of the thermal dissolution of coals of different degrees of metamorphism in the hydrogen-donor solvent tetralin and the anthracene fraction of coal coking tar are compared. It was established that, at 380 degrees C, the dependence of the activity of coal on the metamorphic stage has an extremum. In the tetralin Показать полностьюsolvent, low-rank coals of grades D and G with a loose supramolecular structure and a high concentration of aliphatic fragments exhibited a maximum activity. The resulting product was a viscous flowing mass. In the liquid-phase anthracene fraction, medium-rank coking coals of grades GZh and Zh containing an increased amount of close-packed polycondensed aromatic molecules, were highly active. The process proceeded selectively with the formation of plastic pitch-like products with softening temperatures from 76 to 96 degrees C with little formation of gases and distillate fractions.
