Verfahren zur Darstellung reiner Betortenkohle.
Sowohl bei dem Verfahren zur Erzeugung reiner Retortenkohle gemäss dem Stammpatent Nr. 93744, als auch bei dem Verfahren zur Wärmespaltung von methanhaltigen Gasen gemäss dem österreichischen Patente Nr. 5481 wurden bisher die üblichen Tonretorten als Spaltungsbehälter benutzt. Das Losbrechen der auf die Wandungen abgelagerten Kohlekruste ist umständlich, schädigt den Zersetzungsbehälter und führt zu anorganischen Verunreinigungen des Produktes.
Gemäss der Erfindung werden diese Nachteile dadurch behoben, dass als Material der auf bekannte Art von aussen erhitzten Wände des Zersetzungsraumes aus einem früheren gleichartigen Prozesse stammende reine Methankohle verwendet und nach Beendigung der Methanzersetzung mit der angelagerten Kohle zusammen weiter verarbeitet wird.
Die Spaltung des Methans erfolgt gemäss dem Stammpatent, also derart, dass reine Retortenkohlebrocken in das Kohlenrohr gefüllt und dieses so lange im Betrieb gehalten wird, bis die auf die Wände abgelagerte Kohle den Innendurchmesser des Rohres so weit verringert, dass der weitere Betrieb nicht mehr wirtschaftlich wäre ; da aber das Rohr selbst aus die Spaltung fördernder Kohle gebildet ist, kann man von der Kohlefüllung absehen und nur auf die Rohrwandung die Kohle niederschlagen ; schliesslich kann man zu Beginn das Rohr mit Kohlebrocken füllen, diese werden aber wieder entfernt, wenn der Innendurchmesser eine gewisse Grösse unterschritten hat, wonach die Spaltung ohne Füllung fortgesetzt wird bis das Rohr in einen nahezu vollen Zylinder verwandelt ist.
Nach Beendigung der Spaltung wird mit der auf die Wandung angelagerten Kohle auch das Kohlenrohr selbst zerkleinert, und-da das Rohr aus praktisch demselben Stoffe besteht, wie die angelagerte Kohle-zusammen teilweise auf zur weiteren Spaltung benötigten Kohlerohre, anderseits auf Elektroden usw. verarbeitet.
Selbstverständlich kann man durch bekannte Massnahmen (Verdünnen des Gases, Regelung der Temperatur und der Strömungsgeschwindigkeit) auch erzielen, dass die Kohle teilweise als mit dem Gasstrom mitgeführter Russ entstehen soll, der ausserhalb des Zersetzungsraumes gesammelt wird.

Process for the preparation of pure betort charcoal.
Both in the process for the production of pure retort carbon according to the parent patent no. 93744, as well as in the process for the heat splitting of methane-containing gases according to the Austrian patent no. 5481, the usual clay retorts have been used as cleavage containers. Breaking away the coal crust deposited on the walls is laborious, damages the decomposition container and leads to inorganic contamination of the product.
According to the invention, these disadvantages are eliminated by using pure methane coal as the material of the known type of externally heated walls of the decomposition space from an earlier similar process and further processing it together with the accumulated coal after the methane decomposition has ended.
The cleavage of the methane takes place according to the parent patent, i.e. in such a way that pure retort coal lumps are filled into the coal tube and this is kept in operation until the coal deposited on the walls reduces the inner diameter of the tube to such an extent that further operation is no longer economical would ; but since the pipe itself is formed from coal that promotes the splitting, one can disregard the carbon filling and deposit the coal only on the pipe wall; Finally, the pipe can be filled with lumps of coal at the beginning, but these are removed again when the inside diameter has fallen below a certain size, after which the splitting is continued without filling until the pipe is transformed into an almost full cylinder.
After the end of the cleavage, the coal tube itself is crushed with the coal deposited on the wall, and - since the tube consists of practically the same material as the attached coal - partially processed together on carbon tubes required for further splitting, on the other hand on electrodes etc.
Of course, known measures (dilution of the gas, regulation of the temperature and the flow rate) can also be used to ensure that the coal is partially formed as soot carried along with the gas stream, which is collected outside the decomposition space.
