Abstract

PURPOSE: To efficiently accomplish the titled separation using a product obtd. by ashing a mixt. of an insouble substance and diatomaceous earth as a filtration auxiliary, in separating insolubles substance from a coal liquefaction product obtd. by heating coal slurry in pressurized hydrogen atmosphere.
CONSTITUTION: In a process for separating insoluble substances contg. unreacted coal and mineral materials from a coal liquefaction product obtd. by heating a slurry consisting of coal and a solvent in a pressurized hydrogen atmosphere by filtration, a product obtd. by ashing a mixt. of the insoluble substances and diatomaceous earth at 700W1,300°C is used as a filtration auxiliary. It is possible to continue filtration for a long time because the product has satisfactory noncompressibility like a conventional diatomaceous earth filtration auxiliary. It is possible to exceedingly reduce an amt. of the diatomaceous earth used because the diatomaceous earth once used for filtration can be reused according to this method.
