Abstract

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Kohlenmonoxid in einem mit Kohlenstoff gefüllten, wassergekühlten Generator mit kegelstumpfförmigem Längsschnitt durch Vergasung von Kohlenstoff mit einem Mischgas aus Sauerstoff und Kohlendioxid.The present invention relates to a method for producing carbon monoxide in a carbon-filled, water-cooled generator with a frustoconical longitudinal section by gasifying carbon with a mixed gas of oxygen and carbon dioxide.

Description

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Kohlenmonoxid in einem mit Kohlenstoff gefüllten, wassergekühlten Generator mit kegelstumpfförmigem Längsschnitt durch Vergasung von Kohlenstoff mit einem Mischgas aus Sauerstoff und Kohlendioxid.The present invention relates to a method for producing carbon monoxide in a carbon-filled, water-cooled generator with a frustoconical longitudinal section by gasifying carbon with a mixed gas of oxygen and carbon dioxide.

Die Herstellung von Kohlenmonoxid aus Kohle und Sauerstoff ist ein seit langer Zeit bekanntes großtechnisch geübtes Verfahren. Die zumeist kegelstumpfförmigen Generatoren von zum Beispiel 4 m' Inhalt werden von oben über eine Schleuse mit Koks beschickt und über eine oder mehrere wassergekühlte Düsen am Boden des Generators mit Sauerstoff beaufschlagt. Um den die Düsen mit hoher Geschwindigkeit verlassenden Sauerstoffstrahl bildet sich in einer über 1.800°C heißen Brennzone bei Koksüberschuß die Hauptmenge Kohlenmonoxid, das am Kopf des Generators abgezogen wird. Die Reaktionswärme wird über den den Generator umhüllenden Kühlmantel zumeist an Kühlwasser abgegeben. Wie in der DE-OS 1950 517 beschrieben, ist auch eine Dampferzeugung möglich.The production of carbon monoxide from carbon and oxygen has been a large-scale, practiced process for a long time. The mostly frustoconical generators, for example with a content of 4 m ', are charged with coke from above via a lock and subjected to oxygen through one or more water-cooled nozzles at the bottom of the generator. The main quantity of carbon monoxide, which is drawn off at the top of the generator, forms around the oxygen jet leaving the nozzles at high speed in a burning zone at a coke temperature of over 1,800 ° C. The heat of reaction is mostly given off to cooling water via the cooling jacket enveloping the generator. As described in DE-OS 1950 517, steam generation is also possible.

Nachteilig an dem geschilderten Verfahren ist zunächst, daß die aus der Koksverbrennung zurückbleibende Schlacke sich am Boden des Generators ansammelt. Hierdurch kann die Leistungsfähigkeit der Düse(n) erheblich beeinträchtigt werden; ein Duchrbrennen führt zu Wassereintritten in den Generator und Wasserstoffanteilen im Produktionsgas, die die Weiterverarbeitung erheblich erschweren oder gar gefährden können. Weiterhin ist ein kontinuierlicher Schlackenabzug unmöglich.A disadvantage of the described process is first of all that the slag remaining from the coke combustion accumulates at the bottom of the generator. This can significantly affect the performance of the nozzle (s); Burning through leads to water ingress into the generator and hydrogen in the production gas, which can complicate further processing or can even endanger it. Continuous slag removal is also impossible.

Nachteilig ist ferner, daß die Volumenleistung eines herkömmlichen Generators wegen des stark exothermen Verlaufes der Umsetzung von Kohlenstoff mit Sauerstoff thermisch begrenzt ist. So wird zum Beispiel mit einem Generator von 4 m3 Inhalt bei Zufuhr von reinem Sauerstoff eine maximale CO-Produktion von 140 m3/h erreicht, was einer Volumenleistung von 35 m3 CO/h x m3 Generatorvolumen entspricht. Eine Verbesserung der Wärmezufuhr kann durch Einführung eines kühlbaren, kegelstumpfförmigen Hohlkernes erreicht werden, wie es in der DE-OS 2046 172 beschrieben ist. Deutlich wirkungsvoller ist die Beimischung von Kohlendioxid zum eingespeisten Sauerstoff, da die Reaktion zwischen Kohlendioxid und Kohlenstoff stark endotherm ist. Die Leistung eines Generators von 4 m3 Inhalt kann so bis zu einer Volumenleistung von 60 m3 CO/h x m3 Generatorvolumen gesteigert werden, wobei 02/C02-Verhältnisse von 2 : 1 im Mischgas möglich sind. Leistungsbegrenzend ist auch bei dieser Betriebsweise die Wärmeabfuhr im Bereich der Düse.Another disadvantage is that the volume capacity of a conventional generator is thermally limited due to the highly exothermic course of the reaction of carbon with oxygen. For example, with a generator with a volume of 4 m 3 and a supply of pure oxygen, a maximum CO production of 140 m 3 / h is achieved, which corresponds to a volume capacity of 35 m3 CO / hxm 3 generator volume. An improvement in the heat supply can be achieved by introducing a coolable, frustoconical hollow core, as described in DE - OS 2046 172. The addition of carbon dioxide to the oxygen fed in is significantly more effective, since the reaction between carbon dioxide and carbon is very endothermic. The output of a generator with a content of 4 m 3 can thus be increased up to a volume output of 60 m 3 CO / hxm 3 generator volume, whereby 0 2 / C0 2 ratios of 2: 1 in the mixed gas are possible. The heat dissipation in the area of the nozzle is also limiting in this mode of operation.

Die Aufgabe der vorliegenden Erfindung ist es daher, ein Verfahren zur Herstellung von Kohlenmonoxid zur Verfügung zu stellen, welches effektiver durchzuführen ist und die geschilderten Nachteile der bisher bekannten Verfahren nicht aufweist.The object of the present invention is therefore to provide a process for the production of carbon monoxide which can be carried out more effectively and does not have the disadvantages described of the previously known processes.

Überraschenderweise wurde nun ein Verfahren gefunden, welches alle diese Anforderungen in besonders günstiger Weise erfüllt. Verläßt man nämlich die bisher ausschließlich gewählte Anordnung der Düse(n) am Boden des Generators und führt die Düsen mit einer Richtung nach unten am Generatormantel seitlich ein, so können die geschilderten Nachteile überwunden und eine erhebliche Steigerung der Volumenleistung des Generators unter optimaler Ausnutzung der Reaktionswärme der Kohlenstoff-Verbrennung erreicht werden.Surprisingly, a method has now been found which meets all of these requirements in a particularly favorable manner. If you leave the previously selected arrangement of the nozzle (s) on the bottom of the generator and insert the nozzles in a downward direction on the generator casing, the disadvantages described can be overcome and a considerable increase in the volume capacity of the generator with optimal use of the heat of reaction carbon combustion can be achieved.

Gegenstand der vorliegenden Erfindung ist daher ein Verfahren zur Herstellung von Kohlenmonoxid in einem mit Kohlenstoff gefüllten, wassergekühlten Generator mit kegelstumpfförmigem Längsschnitt durch Vergasung von Kohlenstoff mit einem Mischgas aus Sauerstoff und Kohlendioxid, wobei das Mischgas über eine oder mehrere am Generatormantel angeordnete, nach unten gerichtete kühlbare Düsen in den Generator eingeblasen und das gebildete Kohlenmonoxid entgegengesetzt seitlich und/ oder am Kopf des Generators abgezogen wird. Bevorzugt wird bei diesem Verfahren als Kohlenstoff Koks eingesetzt. Setzt man dem Koks Zuschlagstoffe zu, so ist ein kontinuierlicher oder diskontinuierlicher Abzug der flüssigen Schlacke am Boden des Generators realisierbar.The present invention therefore relates to a process for the production of carbon monoxide in a carbon-filled, water-cooled generator with a frustoconical longitudinal section by gasifying carbon with a mixed gas of oxygen and carbon dioxide, the mixed gas being able to be cooled by one or more arranged on the generator jacket and directed downward Nozzles are blown into the generator and the carbon monoxide formed is drawn off to the side and / or at the top of the generator. Coke is preferably used as the carbon in this process. If additives are added to the coke, the slag can be drawn off continuously or discontinuously at the bottom of the generator.

Besonders effektiv kann das Verfahren durchgeführt werden, indem man ein Volumenverhältnis von Sauerstoff zu Kohlendioxid im Mischgas von bis zu 1 : 1, vorzugsweise 0.83 bis 0,75, einstellt. Dies führt zu einer deutlich verbesserten Nutzung der Reaktionswärme der Kohlenstoff-Verbrennung und einer weiteren Steigerung der Volumenleistung auf über 400 m3 CO/h x m3 Reaktionsvlumen.The process can be carried out particularly effectively by setting a volume ratio of oxygen to carbon dioxide in the mixed gas of up to 1: 1, preferably 0.83 to 0.75. This leads to a significantly improved use of the heat of reaction of the carbon combustion and a further increase in the volume capacity to over 400 m 3 CO / hxm 3 reaction volume.

Eine besonders vollständige Umsetzung zu Kohlenmonoxid kann dadurch erreicht werden, daß über eine oder mehrere oberhalb der Mischdüsen (02/COZ) zusätzlich angebrachte Düse(n) Sauerstoff eingeblasen wird.A particularly complete conversion to carbon monoxide can be achieved in that a multiple above the mixing nozzles (0 2 / CO Z) additionally attached nozzle or (n) oxygen is injected.

Bei der Durchführung des Verfahrens erweist es sich als vorteilhaft, die Düsen mit einem Doppelmantel zur Kühlung auszustatten, der mit Wasser beaufschlagt wird. Ebenso ergibt ein seitlicher Produktionsgasabzug einen weiterer Vorteil, da er die thermische Belastung der mechanischen Einrichtungen zur Koksbeschickung am Kopf des Generators deutlich reduziert.When carrying out the method, it proves to be advantageous to equip the nozzles with a double jacket for cooling, to which water is applied. Likewise, a lateral production gas extraction results in a further advantage, since it significantly reduces the thermal load on the mechanical devices for charging coke at the top of the generator.

In der Fig. 1 wird schematisch ein Kohlenmonoxidgenerator dargestellt, in dem das erfindungsgemäße Verfahren durchgeführt werden kann. Es handelt sich hierbei lediglich um eine denkbare Ausführungsform eines solchen Kohlenmonoxidgenerators.1 schematically shows a carbon monoxide generator in which the method according to the invention can be carried out. It is this just a conceivable embodiment of such a carbon monoxide generator.

Dieser ist mit einem Kühlwassersystem (4) umgeben und weist eine Mischgas (O2/CO2)-DÜse (5) sowie einen Produktgasabzug (6) auf. Die Schlacke (7) kann durch einen Schlackenabzug (8) am Boden des Generators entnommen werden. Ein Mannloch (9) dient der Wartung des Generators. Analog mit ähnlichen Vorteilen, läßt sich das geschilderte Verfahren auch auf andere Gas-Feststoff-Reaktionen übertragen. Beispiele dafür sind die Herstellung von Generatorgas
