This invention is directed to a process for converting coal into useful liquids, solids, and gases, by combined processes of coal carbonization and liquefaction in which the carbonization reaction yields hydrogen suitable for the liquefaction. The heavy liquid products from the liquefaction and the carbonization may be combined with the solid char to form a metallurgical coke.
