Bedeutung ist, wenn das Wassergas aus Kohle unter Gewinnung von Nebenprodukten (Ammoniak und Teer) erzeugt wird.
Zur Durchführung des beschriebenen Verfahrens dient beispielsweise eine Apparatur, wie sie in der schematischen Zeichnung dargestellt ist. Daselbst zeigt J den Ofen, in dem die Retorte 6 angeordnet ist. Die Heizgase strömen bei 4 in den Ofen 3 ein und entweichen bei 7 in den Schornstein. Das 01 fliesst von dem Ölbehälter 11 in die Retorte und wird, wenn dies zur destruktiven Destillation gewünscht wird, von 12 her mit Dampf gemischt bzw. von diesem zerstäubt.
Das Gemisch von Gasen und Dämpfen entweicht durch das Rohr 13 aus dem Unterteile der Retorte und steigt durch den Kühler 14 in die Höhe, wobei es durch heisses Wasser oder Dampf, der bei 15 in den Kühler ein-und bei 16 austritt, nur wenig abgekühlt wird, so dass sich nur die ganz schwer flüchtigen Stoffe (Teer) abscheiden und nach dem Teergefässe 17 abfliessen. Von hier'werden diese teerigen Rückstände durch eine Pumpe 28 angesaugt. und gelangen durch die Rohrleitung 29 zur weiteren Verarbeitung an die Zuführungsstelle des frischen Öles und von hier neuerlich in die Retorte 6. Die Benzindämpfe gehen mit dem Gas gemischt aus dem Dephlegmator.
M zur Abscheidung der schwer kondensierbaren Anteile durch das Rohr 21 zu dem Kühler 22, in welchem sich die Reste des Wasserdampfes und Benzin kondensieren und durch das Rohr 23 abfliessen. Das Olgas entweicht durch das Rohr 24 ; 19 ist ein Wasserabscheider, aus welchem ein Rohr 20 die Teeröle in die Retorte 6 überführt. Die Regenerierung des Kata- lysators erfolgt durch das Gebläse 25, welches der Retorte 6 zur Oxydation des Katalysators
Luft durch das Rohr 13 zuführt. Die Abgase entweichen hiebei durch das Rohr 26 ins Freie.

EMI2.1
It is important if the water gas is generated from coal with the extraction of by-products (ammonia and tar).
An apparatus such as that shown in the schematic drawing is used, for example, to carry out the process described. J shows the furnace in which the retort 6 is arranged. The heating gases flow into the furnace 3 at 4 and escape into the chimney at 7. The oil flows from the oil container 11 into the retort and, if this is desired for destructive distillation, is mixed with steam from 12 or atomized by it.
The mixture of gases and vapors escapes through the tube 13 from the lower part of the retort and rises through the cooler 14, being only slightly cooled by hot water or steam that enters the cooler at 15 and exits at 16 so that only the very poorly volatile substances (tar) separate and flow off after the tar container 17. From here these tarry residues are sucked in by a pump 28. and pass through the pipeline 29 for further processing to the supply point of the fresh oil and from here again into the retort 6. The gasoline vapors leave the dephlegmator mixed with the gas.
M for separating the difficult to condense components through the pipe 21 to the cooler 22, in which the residues of the water vapor and gasoline condense and flow off through the pipe 23. The oil escapes through pipe 24; 19 is a water separator from which a pipe 20 transfers the tar oils into the retort 6. The catalyst is regenerated by the fan 25, which is used in the retort 6 to oxidize the catalyst
Air is supplied through the pipe 13. The exhaust gases escape through the pipe 26 to the outside.
PATENT CLAIMS:
1. Process for increasing the yield of light hydrocarbons when producing oil gas or carburizing gas for water gas or similar gases from heavy mineral oils, tar or the like by destructive distillation using a catalyst (e.g. iron oxide) and water vapor, characterized in that tar and tar oils, which are separated out during the destructive distillation at low temperatures, with the exception of gasoline, are fed entirely to the fresh mineral oil for reprocessing so that only gasoline is obtained as a by-product
