ABSTRACT:
A process for producing liquid hydrocarbons from coal comprises treating comminuted coal at 380.degree. to 600.degree. C. and 260 to 450 bar with water in a high pressure reactor to form a charged supercritical gas phase and a coal residue. Simultaneously with the water treatment, hydrogenation with hydrogen takes place in the presence of a catalyst. The catalyst is selected from the group consisting of NaOH, KOH, Na.sub.4 SiO.sub.4, NaBO.sub.4, or KOB.sub.2. Then, the gas phase is divided into several fractions by lowering its pressure and temperature. Energy and/or gas is generated from the coal residue.
