ABSTRACT:
A method for hydro-liquefying coal, the method comprising preheating a slurried mixture of a pulverized coal and a solvent, the preheated mixture being supplied to a plurality of reactors; separating a gaseous content from the products resulting from the reaction; dehydrating the gaseous content and removing a light oil content therefrom, thereby obtaining hydrogen-content gases; and recycling the hydrogen-content gases at least to the first reactor and supplying it to the bottom thereof so that the light oil content in the solvent is stripped.
