  Verfahren hren zur Herstellung eines Mischgases. Die Erfindung bezieht sieh auf die Herstellung von Gas durch das sogenannte Verfahren der 
 EMI1.1 
 ist, zu   verbilligen   und die Qualität desselben zu verbessern. 



   Bekannt ist die Herstellung von Wassergas aus Kohle oder Koks durch   abwechselnde ? Aufblasen   einer Brennstoffsäule und Durchleiten von Wasserdampf. Das beim Aufblasen entstehende sogenannte   Heissblasegas wird gewöhnlich unausgenutzt ins   Freie entlassen ; bei dem Durchleiten von Dampf entsteht das Wassergas. Ferner ist   vorgeschlagen worden,'Rohkohle   od. dgl. in einer Retorte zu entgasen und den hiebei entfallenden Koks oder Halbkoks in Wassergaserzeugern zu verwenden. In diesem Falle kann das Heizmittel (Wärmeüberträger) aus Wassergas bestehen, dessen fühlbare Wärme ausgenutzt wird, indem einebeliebige Mengevom Wassezgaserzeugerabezogen und   unverbrannt   durch die Retorte geschickt wird, um das in der Retorte zu behandelnde kohlenstoffhaltige Material zu entgasen.

   Als Ergebnis dieses Verfahrens wird eine Gasmischung erzielt, die aus mit Destillationsgas angereichertem Wassergas besteht.   Dieres Mischgas enthält jedoch   einen grossen Prozentsatz von Kohlenoxyd (etwa 30-40%) und obwohl es vom Standpunkte seines Heizwertes aus betrachtet, recht geeignet ist als Ersatz für   gewöhnlichem   
 EMI1.2 
 Kohlenoxyd. 



   In Entgasungsprozessen, bei welchen unverbranntes Gas, wie Wassergas, durch eine Retorte 
 EMI1.3 
 eine vergrösserte Ausbeute an mit Destillationsgas angereichertem Wassergas erhalten, wenn das Heissblasegas, welches während der Blaseperiode bei der Wassergaserzeugung entsteht, ausgenutzt wird. 



  Zu diesem Zwecke wird z. B. bituminöse Kohle in einer Retorte mit Hilfe der fühlbaren Wäime des Wassergases entgast, welchem aus dem beim Retortenprozess entfallenden   kohlenstoffhaltigen Rückstand   erzeugt wird. Der Gaserzeuger, welcher das Wassergas liefert, wird während des Aufblasens in solcher 
 EMI1.4 
 Gemisch aus Retorten-und Wassergas zugesetzt, nachdem das Gemisch die Retorte verlassen hat, u. zw. vorteilhaft dann, wenn die kondensierbaren Kohlenwasserstoffe (Teer, Öle etc.) bereits ausgeschieden sind. Das Ergebnis ist, dass ein viel   grösseres   Volumen Mischgas erzeugt wird mit einem geringeren Prozentsatz Kohlenoxyd. 



   Die auf diese Weise erzeugte grosse Menge Wasserstoff bildet eine sehr wertvolle Zugabe 2um Gasgemisch, wobei gleichzeitig der Prozentsatz an giftigem Kohlenoxyd im   Mischgas   fast auf die   Hpifte   herabgedrückt wird.

  Process for producing a mixed gas. The invention relates to the production of gas by the so-called process of
 EMI1.1
 is to make it cheaper and to improve its quality.



   Is known the production of water gas from coal or coke by alternating? Inflating a column of fuel and passing water vapor through it. The so-called hot-blowing gas that arises during inflation is usually released into the open without being used; When steam is passed through, the water gas is created. It has also been proposed to degas raw coal or the like in a retort and to use the coke or semi-coke that is omitted here in water gas generators. In this case, the heating means (heat exchanger) can consist of water gas, the sensible heat of which is utilized by drawing any amount from the water gas generator and sending it unburned through the retort in order to degas the carbonaceous material to be treated in the retort.

   As a result of this process, a gas mixture consisting of water gas enriched with distillation gas is obtained. The mixed gas, however, contains a large percentage of carbon monoxide (about 30-40%), and although it is quite suitable as a substitute for ordinary one from the standpoint of its calorific value
 EMI1.2
 Carbon dioxide.



   In degassing processes in which unburned gas, such as water gas, is passed through a retort
 EMI1.3
 an increased yield of water gas enriched with distillation gas is obtained if the hot-blowing gas, which is produced during the blowing period during the generation of water gas, is used.



  For this purpose z. B. bituminous coal degassed in a retort with the help of the palpable Wäime of the water gas, which is generated from the carbon-containing residue that is eliminated during the retort process. The gas generator, which supplies the water gas, is in such during the inflation
 EMI1.4
 Mixture of retort and water gas added after the mixture has left the retort, u. or advantageous when the condensable hydrocarbons (tar, oils, etc.) have already been eliminated. The result is that a much larger volume of mixed gas is produced with a lower percentage of carbon dioxide.



   The large amount of hydrogen produced in this way forms a very valuable addition to the gas mixture, while at the same time the percentage of poisonous carbon monoxide in the mixed gas is almost completely depressed.
