Abstract

1. Verfahren zur Sumpfphasehydrierung mit nachgeschalteter Gasphasehydrierung fester kohlenstoffhaltiger Einsatzstoffe. 1. Process for the bottom phase hydrogenation with downstream gas phase hydrogenation more solid carbonaceous feedstocks.

2.1 Bei den bekannten Verfahren müssen definierte Eintrittstemperaturen im Sumpfphase- und Gasphasereaktor sowie bei der Kohleanmaischung eine konstante Phasengleichgewichtstemperatur im Zwischenabscheider für die direkte Lösungsmittelrückführung eingestellt werden. Dies wird erschwert durch veränderliche Wärmeübertragung infolge Verschmutzung der Maischewärmeaustauscher. Die Aufheizung der Einsatzprodukte auf die erforderliche Eintrittstemperatur in das Reaktionssystem der Sumpfphasenhydrierung erfolgt mittels eines im Einsatzproduktstrom mit Fremdwärme betriebenen Aufheizofens. 2.1 With the known methods, defined Entry temperatures in the sump phase and Gas phase reactor and coal mashing a constant phase equilibrium temperature in Intermediate separator for direct Solvent recycle can be set. This is made difficult by changing Heat transfer due to pollution of the Mash heat exchanger. Heating the Insert products to the required Entry temperature in the reaction system of the Bottom phase hydrogenation takes place by means of an Feed product stream operated with external heat Heating furnace.

Die durch Mehrphasenströmung von Gasen, Dämpfen, Flüssigkeit und Feststoff in den Rohren des Aufheizofens gekennzeichneten Verfahrensbedingungen machen die Auslegung und den Betrieb solcher Öfen schwierig. The multi-phase flow of gases, vapors, Liquid and solid in the pipes of the Heating oven marked Process conditions make the design and Difficult to operate such ovens.

2.2 Bei optimierter Ausnutzung der Reaktionswärme aus der Sumpfphase- und Gasphasehydrierung mittels Wärmeaustauscher mit Bypaßbetrieb wird erreicht, daß einerseits die prozeßrelevanten Betriebstemperaturen eingestellt werden und andererseits ein fremdbeheizter Aufheizofen für die ein Dreiphasengemisch darstellenden Einsatzstoffe entfällt und die Zuführung von Fremdwärme auf die Aufheizung eines Teilstromes des Hydriergases in einem Hydriergasofen beschränkt wird. Unter optimierten Bedingungen wird für den Normalbetrieb ein wärmeautarker Prozeß erreicht, so daß der Hydriergasofen (24) nur zum Anfahren oder im stark verschmutzten Zustand der Anlage benötigt wird. 2.2 With optimized utilization of the heat of reaction the bottom phase and gas phase hydrogenation by means of Heat exchanger with bypass operation is reached     that on the one hand the process-relevant Operating temperatures can be set and on the other hand, an externally heated heating furnace for which represent a three-phase mixture No input materials and the addition of External heat on the heating of a partial flow of the hydrogenation gas in a hydrogenation gas furnace is restricted. Under optimized conditions becomes a self-sufficient for normal operation Process reached so that the hydrogenation gas furnace (24) only for starting or in heavily soiled Condition of the system is required.

2.3 Hydrierung und Verflüssigung von Gasflammkohle des Ruhrgebiets. 2.3 Hydrogenation and Liquefaction of Gas Coal Ruhr area.
