ABSTRACT:
A process for producing and then separating distillable and substantially non-distillable coal liquefaction products into various fractions employing a series of extraction solvents. At least one fraction comprises a portion of the non-distillable coal liquefaction products and is suitable for use as a coal solvent, either with or without additional hydrotreating, in the coal liquefaction process. In one embodiment, the coal liquefaction products are contacted with a cascade of extraction solvents, having successively fewer carbon atoms in their molecular structure, at elevated temperatures and pressures to separate the products into various fractions. In another embodiment the coal liquefaction products are contacted with a cascade of extraction solvents, having an increasing number of carbon atoms in their molecular structure, at elevated temperatures and pressures to separate the products into various fractions.
