ABSTRACT OF THE DISCLOSURE . The disclosure describes a method for hydrogenating coal, whereby the coal is stirred into a slurry, the slurry is pumped at reaction pressure, is heated to hydrogena- tion initiating temperature, and is then subjected, in the presence of hydrogen, in a reaction zone, to catalytic hydro- genation. The coal slurry is divided into a first and a second partial flow and is sent to the reaction zone. me first partial flow is heated, outside the reaction zone by heat ex- change with gaseous and vaporous hydrogenation product, while the second partial flow is heated inside the reaction zone by means of exothermic excess heat, produced in the reaction zone at the hydrogenation initiating temperature. This method ena- bles to dispense with regenerators and preheaters thus facili- tating the heating of the fresh coal slurry to the hydrogena- tion initiating temperature.
