ABSTRACT OF THE DISCLOSURE In a method for hydrogenated coal liquefaction, using rubbing oils and hydrogen-containing circulation gas, the non- liquefied solid components are concentrated in a hot separator subsequent to the liquefaction reactor, under similar tempera- ture and pressure conditions as in the reactor. Gaseous and vaporous discharge products from the reactor are condensed in subsequent stages. Non-gaseous and non-vaporous separation products, extensively freed of distillable oils, are removed from the hot separator in still pumpable condition, and relaxed in a subsequent fume extractor. The hydrogen-containing cir- culation gas is conducted through the hot separator in contact with the discharge products from the liquefaction reactor, in an amount greater than 5,000m3, given at standard temperature and pressure per ton of water- and ash-free charge of coal. Variations include branching off part of the circulation gas before the liquefaction reactor and conducting it directly into the hot separator, preheating this branched-off part of the circulation gas before introduction into the hot separa- tor to temperatures between 300° and 550°C, and recovering rubbing oil in an intermediate separation stage directly following the hot separator. -1-
