Description

Verfahren zur Entfeuchtung von nassen Brennstoffen. Zusatz zum Patent 419 906 *). In dem Hauptpatent 4199o6 ist eine Arbeitsweise beschrieben, wonach durch Behandlung von nassen Brennstoffen mit Hilfe von wasserunlöslichen oder in Wasser sehr wenig löslichen Stoffen die Entfeuchtung durchgeführt wird in der Art, daß die Brennstoffe mehrmals mit den Entfeuchtungsinitteln in innige Berührung gebracht werden und vor jeder neuen Vermischung der überschuß der vorhandenen Flüssigkeit in bekannter Weise abgeschleudert oder abgepreßt wird.Process for dehumidifying wet fuels. Addition to the patent 419 906 *). In the main patent 4199o6 a mode of operation is described, according to which by treating wet fuels with the help of water-insoluble or in Water very little soluble substances the dehumidification is carried out in the way, that the fuels are brought into intimate contact with the dehumidifying agents several times and before each new mixing the excess of the existing liquid is thrown off or pressed in a known manner.

Es wurde nun gefunden, daß die in dem Hauptpatent beschriebene Arbeitsweise wesentlich dadurch vereinfacht werden kann, wenn die nassen Brennstoffe einer Erhitzung mit Wasser oder wäßrigen Salzlösungen bei höheren Temperaturen, gegebenenfalls unter Zuhilfenahme von Druck, unterworfen werden. Die auf solche Weise vorbehandelten Brennstoffe ergeben dann durch Behandlung mit den im Hauptpatent genannten Stoffen schon nach einmaligem Abpressen bzw. Abschleudern so geringeWassergehalte, daß eine mehrfache Behandlung mit dein Entfeuchtungsmittel sich in den meisten Fällen erübrigt. Beispiel. Wasserhaltige, grubenfeuchte Braunkohle, welche auf Zoo Teile Reinkohle etwa Zoo Teile Wasser enthält, wird mit Wasser unter Druck auf ungefähr 17o bis 2oo° einige Zeit erhitzt. Die von der Hauptmenge des Wassers befreite Braunkohle wird nunmehr mit dem Entfeuchtungsmittel, z. B. Rohphenol, innig gemischt und in dünner Schicht abgepreßt. Nach erfolgtem Abpressen ergibt sich ein Wassergehalt, der auf Zoo Teile Reinkohle ungefähr 2o bis 25 Teile Wasser enthält.It has now been found that the procedure described in the main patent This can be greatly simplified when heating the wet fuels with water or aqueous salt solutions at higher temperatures, possibly below With the aid of pressure, to be subjected. Those pretreated in this way Fuels then result from treatment with the substances mentioned in the main patent already after a single squeezing or spinning off the water content is so low that a Multiple treatments with your dehumidifier are unnecessary in most cases. Example. Water-containing, pit-moist lignite, which on zoo parts is pure coal Containing about zoo parts of water, water is pressurized to about 17o up 2oo ° heated for some time. The lignite freed from most of the water is now with the dehumidifier, z. B. crude phenol, intimately mixed and in pressed thin layer. After pressing, there is a water content which at zoo parts of pure coal contains about 20 to 25 parts of water.
