The effect of hydrorefining of heavy coal semicoking tar on its composition and efficiency for bituminous coal dissolution was studied. It was found that the concentration of the oxygen-bearing compounds decreased as a result of catalytic hydrotreating with hydrogen or with hydrogen donors. This resulted in improved dissolving power. However, best result in coal dissolution was achieved when heavy semicoking tar was blended with the anthracene oil. The products obtained represented at ambient temperature solid pitch-like matter with the softening points of 124 to 138 °С (“ring and ball” method). It was composed of mainly bi- and three-cyclic aromatics, the content of quinoline-insolubles being less than 6 %, and the ash content less than 0.5 %.
