Description
Verfahren zur katalytischen Umsetzung von Kohlenoxyd-Wasserstoff-Gemischen zu Kohlenwasserstoffen Es ist bereits vorgeschlagen worden, die Umsetzung von; Kohlenoxyd-Wasserstoff-Gasmischungen mit Hilfe flüssiger Katalysatoraufschlämmung vorzunehmen; und die entstehende Reaktionswärme durch zugemischte leichtsiedende Kohlenwasserstoffe abzuführen. Hierbei wurden jedoch nur unbefriedigende Ausbeuten an normal: flüssigen Kohlenwasserstoffei erzielt. Die Umr setzeng verlief außerdem zu träge und lieferte unerwünscht hohe Mengen an gasförmigen Produkten (Methan;).Process for the catalytic conversion of carbon oxide-hydrogen mixtures to hydrocarbons It has already been proposed the implementation of; Carbon dioxide-hydrogen gas mixtures using liquid catalyst slurry; and the resulting heat of reaction to be discharged by mixed low-boiling hydrocarbons. Here, however, were only unsatisfactory yields of normal: liquid hydrocarbons achieved. The conversion was also too sluggish and delivered undesirably high quantities gaseous products (methane;).
Es, wurde die überraschende Beobachtung gemacht, daß diese Nachteile nicht eintreten, wenn während der Umsetzung neben dem Synthesegas Wasser in die Katalysatoraufschlämmung eingep.reßt wird. Die Umsetzung zwischen Kohlenoxyd und Wasserstoff erfolgt unter diesen Umständen trotz weitgehender Aufarbeitung des Kohlenstoffs und Wasserstoffs mit so geringer Methanbildung, wie sie bisher nicht annähernd beobachtet wurde. Auch die Art der entstehenden Reaktionsprodukte kann in überaus gün@ stige.r Weise beeinflußt werden.It was observed, surprisingly, that these disadvantages does not occur if water in addition to the synthesis gas is in the during the reaction Catalyst slurry is pressed in. The implementation between carbon dioxide and Under these circumstances, hydrogen occurs despite extensive processing of the carbon and hydrogen with so little methane formation as it has hitherto not even come close to being observed became. The nature of the resulting reaction products can also be extremely favorable Way to be influenced.
Bei einmaligem Durchgang unter Verwendung von Strömungsgeschwindigkeiten,
die zwischen; i und q. cbm- Synthesegas pro Stunde und Kilogramm Kobalt in einem
Kontakt mit 30o/9 Co-Gehalt lagen, konnte ein Umsatz von 80% und mehr des eingeführten
CO-I-12-Gasgemisches erreicht werdem Die Reaktions-
Abweichend von dieser bisherigen Arbeitsweise wird der Kontakt im ersten Ausführungsbeispiel erfindungsgemäß in einem zwischen 24o und 300°' siedenden Öl suspendiert, wobei man gleichzeitig Wasser in das Reaktionsgemisch einpreßt. Da die Kohlenwasserstofffraktion mit dem zugesetzten Wasser nicht mischbar ist, bildet die Kontaktaufschlämmung ein zweiphasiges Flüssig= keitssystem. Infolge der guten Durchmischung entstehen zahlreiche Greenzflächen zwischen Öl und Wasser. Diese schaumförmigen Grenzflächen wirken außerordentlich günstig auf das Syntheseergebnis.. Die Ausbeute an flüssigen und festen: Kohlenwasserstoffen steigt infolgedessen auf 172 g/cbm Synthesegas und liegt damit erheblich höher als bei der einfachen Kohlenvvasserstofflkontaktaufschlämmung. Dieser Erfolg ist in hohem Maße überraschend, da auf diese Weisse fast theoretische Ausbeuten erreicht werden. Wurde der Wasserzusatz fortgelassen., so ergab sich beider Arbeitsweise nach Beispiel 1 eine Syntheseausbeute von nur 135 g flüssigen und festen Kohlenwasserstoffen pro Kubikmeter Synthesegas.Deviating from this previous way of working, the contact will be in first embodiment according to the invention in a between 24o and 300 ° 'boiling Suspended oil, while at the same time injecting water into the reaction mixture. Since the hydrocarbon fraction is immiscible with the added water, the contact slurry forms a two-phase liquid system. As a result of good mixing results in numerous green areas between oil and water. These Foam-like interfaces have an extremely beneficial effect on the synthesis result. The yield of liquid and solid: hydrocarbons increases as a result 172 g / cbm synthesis gas and is therefore considerably higher than with the simple contact slurry of hydrocarbons. This success is to a large extent surprising, since it is almost theoretical Yields can be achieved. If the addition of water was omitted, both resulted Procedure according to Example 1, a synthesis yield of only 135 g of liquid and solid Hydrocarbons per cubic meter of synthesis gas.
Das vorstehend beschriebene neue Verfahren kann beispielsweise mit Hilfe der in der Zeichnung schematisch dargestellten Apparateanordnung ausgeführt werden.The new method described above can, for example, with Using the apparatus arrangement shown schematically in the drawing executed will.

At the same time you press with the aid of the high pressure pump 8 through line 9 water into the reaction vessel. The introduced water evaporates under the prevailing reaction pressure within the catalyst, raufschläm @ mu, ng.
Die bei der Umsetzung entstehenden Gase und Dämpfe werden durch Leitung 1o abgezogen und einem Kühler 11 zugeleitet. Die nicht kondensierbären Gase entweichen durch Rohrleitung 12 und können anschließend daran mit Hilfe von Aktivkohle absorbiert werden.The gases and vapors produced during the implementation are conducted through conduction 1o withdrawn and fed to a cooler 11. The non-condensable gases escape through pipe 12 and can then be absorbed with the help of activated carbon will.
Das kondensierte Flüssigkeitsgemisch fließt durch Leitung 13 in das Trenngefäß 14. Hier findet die Abscheidung des kondensierten Wassers statt. Dasselbe sammelt sich am Boden des Scheidegefäßes, während die flüssigen Kohlenwasserstoffe bei 15 abfließen.The condensed liquid mixture flows through line 13 into the Separation vessel 14. The condensed water is separated out here. The same thing collects at the bottom of the separator, while the liquid hydrocarbons drain at 15.

Von dort fließt es durch Leitung 18 der Druckpumpe 8 zu, um seinen Kreislauf von neuem z.u beginnen.The end. the separation vessel 14, the water passes through line 16 in the Intermediate container 17. From there it flows through line 18 of the pressure pump 8 to to start its cycle all over again.
Die im Behälter 1 vorhandene Kontaktaufschlämmung erfährt durch während der Reaktion kondensierte schwere öle eine dauernde Versnehrung. Der hierdurch entstehende Flüssigkeitsüberschuß wird, durch Leitung 19 abgezogen. Um hierbei eine gute Trennung von der Kontaktsubstanz zu erreichen, ist ein Filter 2o vorgeschaltet.The contact slurry present in the container 1 experiences through during heavy oils condensed into the reaction, causing permanent deterioration. The resulting Excess liquid is withdrawn through line 19. To get a good separation here To reach from the contact substance, a filter 2o is connected upstream.
Innerhalb des Reaktionsraumes 2 befindet sich ein Thermometer 21. Dasselbe reguliert mit Hilfe der Steuerleitung 22 ein Ventil. 23, welches in die Zuflußleitung für das einzupressende Druckwasser od. dgl. eingebaut ist. Steigt die Reaktionstemperabur in une:Twünschter Weise an, so wird die Zufuhr an verdamp,fbarer Flüssigkeit vergrößert, fällt die Umsetzungstemperatur, so wird der Zuflu:ß an zu verdampfender Flüssigkeit gedrosselt. Auf diese Weise kann. man die ge«lünschte Umsetzungstemperatur innerhalb sehr enger Grenzen, konstant halten.A thermometer 21 is located within the reaction space 2.
