Abstract: The application relates to a process for continuously producing hydrocarbon oils from coal, heavy oils, tars and vacuum residues by pressure hydrocracking in three stages, ground coal with an oil mixture or heavy oils, tars and vacuum residues being pasted with finely disperse catalysts in the first stage, the resulting paste and hydrogen being heated and hydrogenated under pressure (liquid phase) and the gaseous reaction products being separated in hot separators from the liquid and solid reaction products and being passed in one or more reaction chambers over the hydrogenation catalysts arranged in the gas and being hydrogenated again (gas phase), the heat of the end products being transferred by heat exchange to the starting materials. Oils which have condensed out are separated into heavy boilers and light boilers in stripping columns under the system pressure with the aid of the process heat. All three stages, namely liquid phase, refining and hydrocracking, are carried out successively without let-down between the individual stages.
