PROCESS AND CATALYST FOR THE HYDROGENATION OF COAL ABSTRACT OF THE DISCLOSURE Blast furnace flue dust is used as a catalyst in a process for the hydrogenation of coal. A flowable mixture of finely divided coal particles and liquid hydrocarbons is brought to high pressure and to reaction temperature. The mixture is hydrogenated with hydrogen in the presence of blast furnace dust as a hydrogenation catalyst. The cost-effective hydrogenation catalyst is reused profitably subsequent to application in the coal hydrogenation process. Gaseous products are separated from liquid and solid reaction products. Liquid products are vaporized and are fractionated under atmospheric pressure and under vacuum. Hydrogen for use in the hydrogenation is produced by partial oxidation of the residue, and the catalyst is deposted as slag, which is returned to the blast furnace.
