Abstract
The influence of heavy distillate in the recycle solvent in the coal liquefaction process was investigated with a 51 batch-autoclave. The following conclusions are obtained (1) Concentrating in heavy distillate in the recycle solvent causes an inhibition of the coal liquefaction reaction and the solvent hydrogenation reaction. (2) Increase of gas/slurry ratio in the coal liquefaction reaction and sever condition in the solvent hydrogenation reaction are effective countermeasures on the occasion of concentrating in heavy distillate in the recycle solvent.
