FIELD: process engineering.
SUBSTANCE: invention relates to coal liquefaction in organic solvents. Proposed method proceeds from coal grinding, activation and liquefaction in organic solvents and is performed in reactor by pulsed electric discharge in the presence of water, its content making at least 5% by weight of coal. Note that, in preferable version of this invention, ratio of coal to Organic solvent does not exceed 1:2. Obtained mix is then separated into condensed coal to be fed into distillation column (similar to oil distillation column), while undissolved coal is directed back to treatment by electric discharge.
EFFECT: higher quality of coal liquefaction, reduced power consumption.
