TWO STAGE COAL LIQUEFACTION PROCESS WITH PROCESS-DERIVED SOLVENT

摘要

"TWO STAGE COAL LIQUEFACTION PROCESS WITH PROCESS DERIVED SOLVENT" Disclosed is a two-stage process for the production of clean liquid hydrocarbons form 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 aspheltenes prior to recycly to the dissolution stage.
