Process for the hydrogenation of liquid starting substances that contain carbon

Abstract From the Canadian patent

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 …
