TWO-STAGE COAL LIQUEFACTION PROCESS WITH PROCESS-DERIVED SOLVENT HAVING A LOW HEPTANE INSOLUBLES CONTENT

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 at a temperature in the range 425.degree.C-480.degree.C, The dissolver effluent is passed through a catalytic reactor operating under h...

Summary: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 at a temperature in the range 425.degree.C-480.degree.C, The dissolver effluent is passed through a catalytic reactor operating under hydrocracking conditions, including a temperature in the range 340.degree.C-400.degree.C 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,
