ABSTRACT:
A process for producing a superior coal liquefaction solvent. A particulate coal is admixed with a distillable aromatic hydrocarbon solvent and liquefied under predetermined conditions to form coal liquefaction products comprising distillable and substantially nondistillable soluble coal products and insoluble coal products. The distillable solvent and distillable soluble coal products are separated from the remaining liquefaction products. The remainder is admixed with a deashing solvent and separated under elevated temperature and pressure conditions in several separation zones into an insoluble coal products fraction, a light soluble coal products fraction and a heavy soluble coal products fraction. A portion of the light soluble coal products fraction is admixed with the recovered distillable solvent to form the coal liquefaction solvent. The light soluble coal products comprise at least about 15 percent and preferably 25 to 50 percent of the coal liquefaction solvent.
