Abstract—Data on the hydrogenation of coal from the Zashulanskoe field in Transbaikalia in three cycles in
the presence of a recirculating coal distillate solvent with a boiling point of 300–425C are reported. It was
found that the degrees of conversion of the organic matter of coal (OMC) into liquid and gaseous products
reached in the second and third cycles were 85–88%. The yields of liquid products and gases were 81–85 and
6.9–7.4%, respectively, and the consumption of hydrogen was 2.3–2.4%.
