Abstract

PURPOSE: To separate insoluble substances from liquid products with ease and obtain byproducts usable for coke used in the iron industry, etc., in a process for preparing coal liquefaction products containing no insoluble substance by adding organic solvents to the coal and heat-treating the mixtures, characterized by taking insoluble substances out of the reaction zone before disintegration of the said substances.
