Liquefaction of coal

Patent ·
OSTI ID:7318630
This invention provides an improved process for solvent-refining coal which involves heating an admixture of coal and a thermally stable organic solvent to solubilize substantially the coal to form a slurry of liquefaction phase and a residual solids phase, and thereafter passing the slurry through a filter bed of crushed raw coal to separate the liquefaction phase from the solids phase.
