Description

Verfahren zur Herstellung von Wassergas aus Koks und gasförmigen Kohlenwasserstoffen Es ist bekannt, gasförmige Kohlenwasserstoffe mit Sauerstoff in Gaserzeugern mit flüssigem Schlackenabstich (Abstichgeneratoten) zu Kohlenoxyd-Wasserstoff-Gemischen umzusetzen. Heizt man bei diesem Verfahren die umzusetzenden Gase in Wärmeaustauschern auf, so treten infolge vorzeitiger Kohlenwasserstoffspaltung sehr leicht Verstopfungen durch Rußabscheidung auf. Außerdem hat diese Arbeitsweise den Nachteil, daß zur Aufrechterhaltung der Kohlenwasserstoffumsetzung erhebliche Mengen Koks vergast werden müssen.Process for the production of water gas from coke and gaseous hydrocarbons It is known to use gaseous hydrocarbons with oxygen in gas generators liquid slag tapping (tapping generators) to form carbon-oxide-hydrogen mixtures to implement. In this process, the gases to be converted are heated in heat exchangers then blockages very easily occur as a result of premature hydrocarbon splitting by soot deposition. In addition, this mode of operation has the disadvantage that for Maintaining the hydrocarbon conversion gasifies significant amounts of coke Need to become.

Es wurde nun gefumden, daß man dem umzusetzenden Gas vor der Einführung in einen Abstichgeneraxor die nötige Wärme zuführen kann, ohne daß der Vorheizer verstopft wird und ohne daß große Mengen Koks bei nötigt werden, wenn man das mit mindestens 25 Raumprozent Wasserdampf gemischte Gas mit einer Strömungsgeschwindigkeit von mindestens to m/Sek. mit den aus dem Generator. abziehenden heißen Gasen derart in Wärmeaustausch ohne Berührung bringt, -daß seine Temperatur bis etwa 700° C ansteigt, und dann mit Sauerstoff in den Generator einbringt, von dessen Schlacke so viel, wie zur Einstellung der Temperatur der zum Vorheizen der Kohlenwasserstoffe verwendeten, aus dem Generator abziehenden Gase notwendig ist, mindestens aber ao°/o, zusammen mit frischem Koks dem Generator wieder zugeführt wird.It has now been found that the necessary heat can be supplied to the gas to be converted before it is introduced into a tapping generator, without the preheater being clogged and without large amounts of coke being necessary if the gas mixed with at least 25 volume percent water vapor is mixed with a Flow velocity of at least to m / sec. with the ones from the generator. removes hot gases such as heat exchange without contact, -that its temperature rises to about 700 ° C, and then introduces with oxygen into the generator, of its slag as much as to adjust the temperature of the hydrocarbons used to preheat the Generator extracting gases is necessary, but at least ao ° / o, is fed back to the generator together with fresh coke.

Die gleichzeitige Anwendung dieser Maßnahmen ermöglicht es, unter Aufwand einer verhältnismäßig kleinen Menge Koks die Temperatur der aus dem Generator austretenden Gase so zu regeln, daß diese ohne weiteres zur Aufheizung der umzusetzenden Gase verwendet werden können, ohne daß die Gefahr besteht, daß der Vorwärmer durch Buß-oder Harzabscheidungen verstopft wird.The simultaneous application of these measures makes it possible to take Expenditure of a relatively small amount of coke increases the temperature of the generator to regulate escaping gases so that they can easily be used to heat the Gases can be used without the risk of the preheater through Penetration or resin deposits become clogged.

Man hat zwar schon bei Gaserzeugern, die mit Luft betrieben werden, zur Beeinflussung des Ofenganges vorübergehend kleine Mengen Abstichschlacke in den Generator zurückgeführt. Eine solche Rückführung wäre aber bei den mit Sauerstoff betriebenen, also sehr heiß gehenden Generatoren, die allein nach der vorliegenden -Erfindung verwendet wer-' den sollen, zur Erleichterung des Ofenganges völlig überflüssig. Bei dem Verfahren nach der Erfindung wird nicht eine kleine Menge, sondern ein großer Teil der Schlacke zurückgeführt, um so die Gasaustrittstemperatur zu regeln und damit ein störungsfreies Aufheizen der umzusetzenden Gase zu ermöglichen.It is true that gas generators that are operated with air to influence the furnace passage temporarily small amounts of tapping slag in returned the generator. Such a return would be at the generators operated with oxygen, i.e. very hot ones, that alone to be used according to the present invention, to facilitate the Oven course completely superfluous. In the method according to the invention is not one small amount, but a large part of the slag returned, so as to reduce the gas outlet temperature to regulate and thus enable trouble-free heating of the gases to be converted.

Als Ausgangsgase kommen z. B. Koksofengas oder die bei der Hydrierung von Kohle oder Ölentstehenden methanhaltigen Abgase in Betracht. Diese werden nach der Aufheizung mit so viel-Sauerstoff in den Generator eingeführt, wie zur Umsetzung der Kohlenwasserstoffe zu Wasserstoff und Kohlenoxyd, zur Verbrennung des dabei entstehenden Kohlenstoffs und zur Vergasung des Kokses notwendig ist.As starting gases come z. B. coke oven gas or the hydrogenation methane-containing exhaust gases from coal or oil can be considered. These will be after the heating with as much oxygen introduced into the generator as to implement the hydrocarbons to hydrogen and carbon oxide, for the combustion of it resulting carbon and gasification of the coke is necessary.

Von der aus dem Generator austretenden Schlacke werden 2o bis 8o11, in diesen zurückgeführt. Die Menge Schlacke, die in jedem einzelnen Fall notwendig ist, um die Temperatur - der aus dem Generator austretenden Gase auf die für das 4ufheizen der Ausgangsstoffe nötige Temperatur einzustellen, läßt sich leicht durch Versuche ermitteln.From the slag emerging from the generator, 2o to 8o11, fed back into this. The amount of slag required in each individual case is to set the temperature - of the gases exiting the generator to the one for that 4heating the starting materials to set the necessary temperature can easily be achieved Identify attempts.
