Abstract A process is disclosed for the hydrogenation of starting materials that contain carbon. In the known processes, the heating of the starting materials to the required entry temperature for the reactor for liquid-phase hydrogenation is effected by means of a heating oven, powered by external heat. Operating conditions characterized by multiphase flow of gases, vapours, liquid, and solids in the tubes of the heating oven make designing and operating such ovens very difficult. The new process is intended to make it possible to dispense with an oven of this kind. The extensive, optimized use of thermal energy by means of heat exchange in counterflow to the starting materials which are a mixture of phases, makes it possible to limit the supply of external heat for heating of a substream of hydrogenating gas in a hydrogenating-gas oven.
