Abstract

The main process characteristics of the thermal dissolution of grade Zh coal in the anthracene fraction of coking tar depending on temperature and reaction time were determined. It was established that the effective extraction of quinoline-soluble products occurred in a temperature range of coal conversion into a plastic state. The process proceeded selectively; at 350–380°C, the yield of the quinoline-soluble products was 71–75%. In this case, the yield of toluene-soluble products did not exceed 10%, and the yield of gas was 0.5%. At a higher temperature and a long reaction time (>2 h), a sharp decrease in the characteristics of thermal dissolution occurred.
