EMI1.1
Im Stamm-Patente ist ein Verfahren zur Darstellung vom Ammoniak beschrieben, wobei man ein Luft. Wasserdampfgemisch auf kohlenstoffhaltige Materialien, insbesondere Torf, einwirken lässt, ohne jedoch die Temperatur von 5500 C bei der Reaktion zn über- schreiten. IIiebei wird der Kohlenstoff ohne Fouererscheinung unter gleichzeitiger Bildung von Ammoniak verbrannt. In der Praxis wird das Verfahren in der Weise ausgeführt, dass man ein auf etwa 400 C erhitztes bzw. überhitztes Luft-Wasserdamfpgemisch über die in

die geeignete Temperatur von etwa 4000 C erreicht hat, findet eine reichliche Entwicklung von Ammoniak statt. Die Reaktion ist eine exothermische, d. h. es wird Wärme frei.
Ilio- durch ist es nicht ganz leicht, die Rcaktionstemperatur von 55Uo C im Maximum innezuhalten, da eine stete Neigung zum Steigen der Temperatur vorhanden ist. Man muss daher mit grosser Sorgfalt auf die Einhaltung der richtigen Temperatur achten und durch vermehrtes Einblasen von Dampf die Temperatur im Ofen erniedrigen.
Es wurde nun gefunden, dass die bei der Reaktion freiwerdende Wärme vollkommen

Man setzt also den Ofen in bekannter Weise durch Einleiten eines auf etwa 4000 C

EMI1.1
In the parent patents a process for the preparation of ammonia is described, whereby one air. Allowing the water vapor mixture to act on carbonaceous materials, especially peat, without, however, exceeding the temperature of 5500 C during the reaction. In the process, the carbon is burned without burning, with the simultaneous formation of ammonia. In practice, the process is carried out in such a way that an air / water vapor mixture heated or superheated to approximately 400 C. is passed through the in
EMI1.2
has reached the appropriate temperature of about 4000 C, an abundant evolution of ammonia takes place. The reaction is an exothermic one; H. heat is released.
In general it is not very easy to maintain the reaction temperature of 55 ° C. at its maximum, since there is a constant tendency to rise in temperature. It is therefore necessary to take great care to maintain the correct temperature and to lower the temperature in the furnace by blowing in more steam.
It has now been found that the heat released during the reaction is complete
EMI1.3
to maintain the material without external supply of heat. The essence of the present invention is based on this observation.
So you set the furnace in a known manner by introducing a to about 4000 C.
EMI1.4
as a means of burning the carbon, air and water were introduced into the furnace in the form of a very fine noble at ordinary temperature. This way of working doesn't have
