ABSTRACT:
Disclosed is a two-stage process for the production of clean liquid hydrocarbons from coal. In the process sub-divided coal is dissolved in a process-derived solvent. The dissolver effluent is passed through a catalytic reactor operating under hydrocracking conditions, to produce normally liquid products and recycle solvent. The solvent is further subjected to treatment with an antisolvent to precipitate unconverted asphaltenes prior to recycle to the dissolution stage.
