ABSTRACT:
A method of liquefying coal in which coal is mixed with a process solvent comprising at least partially hydrogenated coal tar material to produce a coal-solvent slurry. This slurry is treated under coal-liquefying conditions, preferably including a hydrogen atmosphere and elevated temperatures, to produce a solution containing coal liquefaction products. These products are recovered from the solution. Recovered, process-derived solvent material may be recycled in order to supplement the at least partially hydrogenated coal tar material as an ingredient of the process solvent.
