FP-3612/HO ABSTRACT OF THE DISCLOSURE A process for manufacturing metallurgical carbonaceous from coals, particularly coals of a low rank of coalification, in which coal fines and a hydrocarbon base solvent having a boiling point of 150° to 500°C are mixed together into a slurry form, then the slurry is subjected to a first heat treatment wherein the slurry is treated in the presence of a mixture gas including carbon monoxide and steam under a pressure of 50 to 300 atms. and temperature of 300° to 600°C, and then the reaction product thus derived is subjected to a second heat treatment wherein the reaction product is treated in the presence of a hydrogen gas at a low partial pressure, at a pressure 10 mmHg to 250 atms, and temperature of 400° to 600°C.
