Description

Verfahren zur kontinuierlichen Umwandlung von Steinkohlenschwelgas in ein Stadtgas Die Erfindung betrifft ein Verfahren zur kontinuierlichen Umwandlung von Steinkohlenschwelgas in ein Stadtgas und besteht darin, daß das vom Teer befreite Schwelgas in einem Schacht durch mittelbar auf bestimmte Temperatur erhitzten Koks geleitet wird, wobei die festgelegte Verweilzeit des Schwelgases im Koksbett mittels fein einstellbarer Gebläse reguliert wird.Process for the continuous conversion of coal smoldering gas into a town gas The invention relates to a method for continuous conversion of coal smoldering gas into a town gas and consists in the fact that that freed of tar Carbonization gas in a shaft using coke indirectly heated to a certain temperature is passed, the specified residence time of the carbonization gas in the coke bed means finely adjustable fan is regulated.

Die Erfindung unterscheidet sich grundsätzlich von einem bekannten diskontinuierlichen Verfahren, bei dem im Blase-Gasebetrieb für kurze Zeit das Schwelgas in die Koksmasse geleitet wird, um die gewünschte Spaltung der schweren Kohlenwasserstoffe durchzuführen. Darauf wird wieder Luft zur Erhöhung der Kokstemperatur eingeblasen. Es handelt sich also nicht um eine stetige Umwandlung des Steinkohlenschwelgases in ein Stadtgas.The invention differs fundamentally from a known one discontinuous process in which the carbonization gas is used for a short time in bubble gas operation is passed into the coke mass in order to achieve the desired splitting of the heavy hydrocarbons perform. Air is then blown in again to increase the coke temperature. So it is not a question of a constant conversion of the coal smoldering gas in a town gas.

Das bei Tieftemperatur stetig erzeugte Schwelgas gewinnt wegen seiner wertvollen Zusammensetzung für die chemische Industrie und auch für die Wärmewirtschaft an Bedeutung.The carbonization gas, which is constantly generated at low temperatures, wins because of it valuable composition for the chemical industry and also for the heating industry in importance.

Die Erfindung bezweckt, dieses hochwertige Gas nicht nur für industrielle Zwecke zu verwenden, sondern durch ganz bestimmte Umwandlung auch eine Gaszusammensetzung für ein Stadtgas herzustellen.The invention aims to make this high quality gas not only for industrial use Purposes to use, but also a gas composition through a very specific conversion for a town gas.

Der Erfindung liegt die Überlegung zugrunde, daß auch das bei Hochtemperatur erzeugte Destillationsgas von 5000 k/cal/Nm3 in seiner ersten Entwicklungsphase gleichfalls die Tieftemperatur durchlaufen hat - wenn auch nur für eine kurze Dauer - und die hierbei entstandenen Zersetzungsprodukte gleichfalls ,Schwelgas.. gewesen sein müssen, um hierauf anschließend die hochtemperierte Koksschicht zu durchziehen und dabei zu Destillationsgas umgewandelt zu werden.The invention is based on the idea that that too at high temperature produced distillation gas of 5000 k / cal / Nm3 in its first development phase has also passed through the low temperature - even if only for a short period of time - and the resulting decomposition products also, smoldering gas .. have been must be in order to then pull through the high-temperature coke layer and being converted to distillation gas in the process.

In der analogen Anwendung, um nachträglich das Schwelgas in ein Destillationsgas umzuwandeln, ist die Kenntnis der Zusammensetzung beider Gase erforderlich. Zu diesem Zweck ist nachstehend eine Gegenüberstellung von Steinkohlenschwelgas von 500° und Steinkohlengas von 1000° für zwei verschiedene Kohlenentgasungen angeführt (Gaskursus, Gasinstitut Karlsruhe 1946. Verlag G. Braun G.m.b.H., Karlsruhe). Steinkohlen- Steinkohlen- schwelgas gas 500° 1000` N.............. 2,50/, 2,50/, 2,001, C", H" .......... 8,0()/, 3,5 0/0 4,00/, C O ............ 5,50/, 8,0 0/0 8,00/0 CH, u. H", .. ... 65,0 0jo 50,00/, 34,00/, H.............. 10,00/, 34,00/, 50,00/, Co, ........... 9,00/, 2,001, 2,00/, Heizwertl'Nm3 7000 kcal 5000 kical 5000 kcal Der Vergleich der Zusammensetzung der drei Gase läßt unschwer ihre Zusammengehörigkeit erkennen, wobei ersichtlich ist, daß die vorherrschende Stellung der Kohlenwasserstoffverbindungen im Schwelgas durch die erhöhte Temperatur bei 1000° aufgehoben und dafür die Wassergasanteile des Destillationsgases angereichert werden. Dieser teilweise Zerfall der Kohlenwasserstoffe sowie die Reduktion C02 + O = 2 CO sind jeweils mit Volumenvermehrung verbunden. Da die Zersetzung der Kohlenwasserstoffe (CH, und CmH") in starkem Maße von der Temperatur an sich abhängt, aber auch von der Dauer der Temperatureinwirkung, so sind damit die Bedingungen für eine nachträgliche Umwandlung des Schwelgases in ein Stadtgas herausgestellt. Dieser Begriff des Stadtgases ist hinsichtlich des spezifischen Heizwertes in den verschiedenen Ländern unterschiedlich. Die Schweiz hat den Heizwert des Destillationsgases mit 5000 kcal auch für das Stadtgas beibehalten, während in anderen Ländern der Heizwert des Stadtgases niedriger liegt als der des Destillationsgases und durch abzumessende Beigabe von Wassergas von Fall zu Fall zu regeln ist.In the analogous application, in order to subsequently convert the carbonization gas into a distillation gas, knowledge of the composition of both gases is required. For this purpose, a comparison of hard coal smoldering gas of 500 ° and hard coal gas of 1000 ° for two different coal degassing is given below (gas course, Gas Institute Karlsruhe 1946. Verlag G. Braun GmbH, Karlsruhe). Hard coal hard coal carbonization gas 500 ° 1000` N .............. 2.50 /, 2.50 /, 2.001, C ", H" .......... 8.0 () /, 3.5 0/0 4.00 /, CO ............ 5.50 /, 8.0 0/0 8.00 / 0 CH, u. H ", .. ... 65.0 0jo 50.00 /, 34.00 /, H .............. 10.00 /, 34.00 /, 50.00 /, Co, ........... 9.00 /, 2.001, 2.00 /, Calorific value l'Nm3 7000 kcal 5000 kical 5000 kcal The comparison of the composition of the three gases shows that they belong together, whereby it can be seen that the predominant position of the hydrocarbon compounds in the carbonization gas is canceled out by the increased temperature at 1000 ° and that the water gas components of the distillation gas are enriched instead. This partial decomposition of the hydrocarbons and the reduction of C02 + O = 2 CO are each associated with an increase in volume. Since the decomposition of the hydrocarbons (CH, and CmH ") depends to a large extent on the temperature itself, but also on the duration of the temperature exposure, the conditions for a subsequent conversion of the carbonization gas into town gas are emphasized. This concept of town gas is different in terms of the specific calorific value in the different countries. Switzerland has retained the calorific value of the distillation gas at 5000 kcal for the town gas, while in other countries the calorific value of the town gas is lower than that of the distillation gas and by adding water gas to be measured on a case-by-case basis Case is to be settled.
