A process for producing hydrocarbonaceous products from coal which includes contacting coal with water, a reducing gas and a catalytic sulfur compound, separating the liquefied coal phase from an aqueous phase, contacting the liquefied coal phase with water to remove ash, extracting the resulting low ash coal liquids with an aromatic hydrocarbon solvent to recover a first, ash-free, hydrocarbonaceous product, and further extracting the raffinate from the aromatic extraction operation with a solvent mixture of a polar hydrocarbonaceous solvent and an aromatic solvent to recover a second, ash-free hydrocarbonaceous solvent and an aromatic solvent to recover a second, ash-free hydrocarbonaceous product.
