Two-stage coal liquefaction process with process-derived solvent having a low heptane-insolubles content |
摘要 |
Disclosed is a two-stage process for the production of clean liquid hydrocarbons from coal. In the process subdivided 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 cooled to precipitate unconverted heptane-insolubles prior to recycle to the dissolution stage.
