ABSTRACT:
Coal is liquefied by treatment with a hydrogen-donor solvent and gaseous hydrogen, a heavy bottoms product boiling primarily in excess of about 1000.degree. F. is recovered, and this bottoms product is then pyrolyzed with fresh coal to produce surprisingly high yields of liquid product. The coke formed during the pyrolysis step may be gasified to generate hydrogen for use in the liquefaction operation and additional gas which can be employed as a fuel or upgraded for other uses.
