ABSTRACT:
A process for producing hydrogen-enriched hydrocarbonaceous products from coal which comprises: (a) contacting the coal in a solvent extraction zone at solvent extraction conditions with a coal solvent, hydrogen and a first residual oil containing asphaltenes and at least one finely divided, unsupported metal sulfide to provide a liquid effluent slurry which includes a low boiling hydrocarbon soluble fraction; (b) contacting at least a portion of the liquid effluent slurry from the solvent extraction zone of step (a) with a low boiling hydrocarbon solvent in a solvent separation zone at solvent separation conditions to separate the low boiling hydrocarbon soluble fraction from a low boiling hydrocarbon insoluble fraction which comprises ash, unconverted asphaltenes and finely divided, unsupported metal sulfide; (c) contacting the low boiling hydrocarbon soluble fraction from step (b) with hydrogen and a second residual oil containing asphaltenes and at least one finely divided, unsupported metal sulfide in a hydrocarbon reaction zone at hydrocarbon conversion conditions; and (d) recovering hydrogen-enriched hydrocarbonaceous products from the effluent of the hydrocarbon reaction zone of step (c).
