Abstract

Bei diesem Verfahren zur Aufarbeitung von Rückständen der Kohlehydrierung durch Vakuumdestillation erfolgt die De­ stillation bei Drücken von 0.01 bis 0.6 bar. In this process for processing residues the coal hydrogenation by vacuum distillation takes place the De Stillation at pressures from 0.01 to 0.6 bar.

Zwecks verbesserter Handhabung derartiger Rück­ stande, insbesondere das Austragen aus der Vakuumkolonne betreffend, wird der Hydrierrückstand in einer ein- oder mehr­ welligen Schneckenmaschine einer Destillation unter vermin­ dertem Druck unterworfen, wobei die entstehenden Gase und Dämpfe abgezogen werden und der nicht verdampfte Rest in eine Kühl- und Granuliervorrichtung gebracht wird. For the better handling of such re stood, especially the discharge from the vacuum column Concerning, the hydrogenation residue in one or more undulating screw machine of a distillation under min subjected to pressure, the resulting gases and Vapors are drawn off and the unevaporated rest in a cooling and granulating device is brought.
