Abstract
The thermal dissolution of grade 1GZh coal in different commercial paste-forming agents—coking tar, an anthracene fraction of coking tar, heavy semicoking tar, and petroleum gas oil—was studied. It was established that the presence of polycondensed molecules with a low degree of substitution of aromatic rings and compounds with hydrogen-donor and solvating activity in the solvent facilitated the efficient occurrence of the thermal dissolution of coal at a low temperature of 380°C. The highest yields of soluble pitch-like product (78–85%) were obtained in the processes performed in the anthracene fraction of coking tar and coking tar.
