  Verfahren zur Gewinnung von Ammoniak mittels der aus den Retorten oder Kammern bei der trockenen Destillation von Kohle nach deren Vergasung ausgestossenen glühenden
Koksmassen. 



   Es ist bereits bekannt, die aus den Retorten oder Kammern bei der trockenen Destillation von Kohle nach deren Vergasung ausgestossenen glühenden   Eoksmassen   in geschlossene, mit einem Doppelmantel umkleidete Behälter zwecks Verdampfung des im Doppelmantel befindlichen Wassers zu bringen. 



   Es ist ferner nicht mehr neu, durch Einwirkung von Wasserdampf und Stickstoff auf glühende Koksmassen Ammoniak zu gewinnen. Bei derartigen Verfahren ist auch die 
 EMI1.1 
   Kokmassen   gleichzeitig Wasserdampf und freien Stickstoff enthaltende Gase einwirken lässt. 



     Dadurch erhätt man   eine Ausbeute an   Ammoniak,   die jene nach den bekannten Verfahren wesentlich übersteigt ebenso wird der Heizwert der ammeniakhaltigen Gase gesteigert.

 Jeiten, deren Decken aber nicht beheizt werden dürfen und welche bis zu diesen mit Kohlen gefüllt sein müssen, damit eine Zersetzung der erzeugten Produkte durch Über-   bit/ung     vermieden   wird. Selbstverstandlich darf die Temperatur der Durchleitretorten keine zu hohe sein, damit nicht die weitere   Ammoniakbiidung behindert   wird : die hiefür günstige   Retortentemperatur   ist jeweils durch Ausprobieren festzustellen. 



   Statt reinen Stickstoff zu verwenden, kann man auch Rauchgase benutzen, die zweck- 
 EMI1.3 
 Stickstoff und bis zu 20% Kohlensäure bestehen. Letztere wird durch den glühenden Koks zu Kohlenoxyd reduziert, welches den Heizwert des Gases erhöht, während der Stick-   stoff sich mit   dem bei der Wassordampfzersetzung entstehenden Wasserstoff zu Ammoniak   vronigt.   



     Die Vorbehandiung bzw. Reinigung der Ranchgase   besteht darin, dass die in denselben enthaltenen Schwefelverbindungen entfernt werden, da sonst Unzuträglichkeiten, insbesondere durch   Hihiung von Schwefelwasserstoff   beim Verbrauch des Gases in den Wohnungen eintreten   würden. Zu diesem Zwecke werden   die   Uanehgase,   wie das in den Retorten hergestellte, Leuchtgas durch mit Rasen-Eisenerz oder Eisenoxydhydrat gefüllte Kästen hindurch-   geJf1itet     bzw. gedrückt.

   Dies   muss unbedingt vor der Zumischung der umgewaudelten

 bekanntlich in gleichen Einrichtungen erfolgt, ungenügend wäre, da die Reinigungsanlage, die bei den Gaswerken mbist nur so bemessen ist, dass sie gerade für die mit dem er-   zeugten Gas entstehenden Mengen   von Schwefelverbindungen genügt, sonst   überlastet würde.   



   Zur Ausführung des Verfahrens ausserhalb der Retorten kann die in der Zeichnung Im Schnitt dargestellte Einrichtung dienen.

Der Mantelraum b dient zur Aufnahme von Wasser, das durch die Leitung e zugeführt und durch die von dem glühenden Koks ausgestrahlte Hitze erwärmt und zum Verdampfen gebracht wird. Der Wasserdampf wird oben aus dem Mantelraum, b durch die Leitung f entnommen und unten in den   Koksraum a zugeführt. Gegebenenfalls   können auch noch durch die Leitung   g,   die an die   Leitung f angeschlossen   ist, weitere Mengen von Wasserdampf zugeleitet werden.

   Sind nur ausgraphitierte Retorten oder Kammern vorhanden, so können die im Koksablöschbehilter erhaltenen Gase nicht durch die frisch beschickten Retorten oder Kammern geleitet werden, sondern werden zweckmässig durch die Vorlage direkt dem Retortenbzw. Kammergas beigemischt und gehen mit diesem durch die Reinigung. Die Ausbeute an Ammoniak ist im letzteren Falle aber nur unbedeutend geringer.

  Process for obtaining ammonia by means of the glowing emitted from the retorts or chambers during the dry distillation of coal after its gasification
Coke masses.



   It is already known to bring the glowing eok masses ejected from the retorts or chambers during the dry distillation of coal after its gasification into closed containers lined with a double jacket for the purpose of evaporating the water in the jacket.



   Furthermore, it is no longer new to extract ammonia by the action of steam and nitrogen on glowing coke masses. In such procedures, the

   Allowing coke masses to act simultaneously with gases containing water vapor and free nitrogen.



     This gives a yield of ammonia which substantially exceeds that obtained with the known processes, and the calorific value of the gases containing ammenia is increased.

 Jeiten, the ceilings of which may not be heated and which have to be filled with coal up to these, so that the products produced are prevented from decomposing due to overbiting. Of course, the temperature of the pass-through retorts must not be too high, so that further ammonia formation is not hindered: the retort temperature that is favorable for this must be determined by trial and error.



   Instead of using pure nitrogen, you can also use flue gases that
 EMI1.3
 Nitrogen and up to 20% carbonic acid. The latter is reduced to carbon oxide by the glowing coke, which increases the calorific value of the gas, while the nitrogen is converted into ammonia with the hydrogen produced during the decomposition of water vapor.



     The pretreatment or cleaning of the ranch gases consists in removing the sulfur compounds contained in them, since otherwise there would be inconveniences, in particular through the addition of hydrogen sulfide when the gas is consumed in the apartments. For this purpose, the uranium gases, like the luminous gas produced in the retorts, are passed or pressed through boxes filled with turf iron ore or iron oxide hydrate.

   This must be done before adding the converted

 as is known, takes place in the same facilities, would be inadequate because the cleaning system, which is only dimensioned at Gaswerke mbist in such a way that it is just sufficient for the quantities of sulfur compounds produced with the gas produced, would otherwise be overloaded.



   The device shown in section in the drawing can be used to carry out the method outside the retorts.

   can be closed, the nozzle d of which is connected to the retorts or chambers. The jacket space b serves to hold water, which is fed in through the line e and heated by the heat radiated from the glowing coke and made to evaporate. The water vapor is taken from the jacket space at the top, b through line f and fed into the coke space a at the bottom. If necessary, further amounts of water vapor can also be fed in through the line g, which is connected to the line f.



   The pipe used to supply nitrogen or flue gases is denoted by h.



   If there are only graphitized retorts or chambers, the gases obtained in the coke extinguishing filter cannot be passed through the freshly charged retorts or chambers, but are conveniently transferred directly to the retorts or Chamber gas mixed and go with this through the cleaning. In the latter case, however, the ammonia yield is only insignificantly lower.
