    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.

    Abstract: Process for flaring off the let-down gases from reactors of a liquid-phase hydrogenation of coal or heavy oil, the reaction product leaving the reactors in vapour form together with unreacted hydrogen and gaseous C1-C4 hydrocarbons formed, this stream being cooled and the hydrocarbons condensing out, and the hydrocarbon condensate of the gases being separated in a cold separator, the pressurised gases leaving the cold separator being used as a propellant gas medium for the intake of combustion air for the flaring of the let-down gases.

    Abstract: The device for distributing a hydrogenation gas in a hydrogenation reactor consists of a cylindrical reaction part and two spherical ends, the hydrogenation gas and the coal suspended in a liquid being fed together to the hydrogenation reactor via a line arranged centrally in the lower spherical end, and an impingement plate being provided above the outlet of the centrally arranged line in the lower spherical end. With this impingement plate, rapid and uniform distribution of the hydrogenation gas from the cross-section of the feed line to the very much larger cylindrical reactor cross-section is achieved and, at the same time sedimentation of the finely disperse coal is prevented.
