In a coal liquefaction process which includes a recycle of a product slurry which contain recycle mineral residue and recycle of extraneous catalytic material to said liquefication zone, hydrocracking of the hydrocarbonaceous material from the mineral residue occurs and a mixture of hydrocarbon gases, dissolved liquid, normally solid dissolved coal, suspended mineral residue and suspended extraneous catalytic mineral results. A first portion of said residue slurry is recycled to the… CONTINUE READING
