Description

Verfahren zur Abscheidung organischer Gase bzw. Dämpfe Zusatz zum Patent 310 092**) Durch das Hauptpatent ist ein Verfahren zur Abscheidung von organischen Gasen bzw. von vergasten organischen Körpern aus ihren Gemischen mit Luft oder anderen schwer bzw. nicht absorbierbaren Gasen, wie Wasserstoff, geschützt. Es besteht darin, daß man solche Gemische mit besonders poröserKohle, wie sie nach dem Verfahren der Patentschrift 290 656 hergestellt werden kann, behandelt und die von der Kohle absorbierten organischen Körper wieder mit Hilfe von Wasser. dampf in der Hitze austreibt.Process for separating organic gases or vapors Patent 310 092 **) The main patent is a process for the separation of organic Gases or from gasified organic bodies from their mixtures with air or others difficult to absorb or not absorbable gases such as hydrogen. It is, that one such mixtures with particularly porous carbon, as they are according to the method of Patent Specification 290 656 can be produced, treated and absorbed by the coal organic body again with the help of water. expels steam in the heat.

Bei Ausführung dieses Verfahrens sowie derjenigen der Zusätze 386 678, 393 865, 435 013 und 455 I75 erwärmt sich leicht die Kohle, so daß Gefahr einer Entzündung auftritt. Dies kann man, wie gefunden wurde, dadurch vermeiden, daß man die Kohle mit einer hinreichenden lVf Menge Wasser belädt. When carrying out this procedure as well as that of Additions 386 678, 393 865, 435 013 and 455 I75 heats up the coal slightly, so that there is a risk of a Inflammation occurs. As has been found, this can be avoided by the coal is loaded with a sufficient amount of water.

Man erreicht dies z. B. dadurch, daß man sie vor der Benutzung mit Wasserdampf behandelt.This is achieved e.g. B. by having them before use Steam treated.

Beispiel Durch ein mit Holzkohle (Patentschrift 290 656) gefülltes zylindrisches Gefäß wird so lange um einige Grad überhitzter Wasserdampf von 100 bis 110°C geleitet, bis die Kohle die Temperatur des Dampfes angenommen hat. Darauf wird die Kohle durch eingeblasene kalte Luft abgekühlt und dann ein mit Benzoldampf bei I50 C gesättigter Luftstrom hindurchgeleitet. Die während der Absorption beobachtete Höchsttemperatur beträgt 380 C. Nach eingetretener Sättigung wird das absorbierte Benzol durch Wasserdampf ausgetrieben und von mitkondensiertem Wasser getrennt. Die Kohle wird nach dem Wiedererkalten sofort wieder benutzt. Example Through a filled with charcoal (patent specification 290 656) Cylindrical vessel becomes so long a few degrees superheated water vapor of 100 up to 110 ° C until the coal has assumed the temperature of the steam. Thereon the coal is cooled by blown cold air and then a with benzene vapor at 150 C saturated air flow passed through. That observed during absorption The maximum temperature is 380 C. After saturation has occurred, the absorbed Benzene expelled by steam and separated from condensed water. The coal is used again immediately after it has cooled down again.

Verwendet man z. B. eine Kohle, die I9,8 °/o Feuchtigkeit enthält, so wird von ihr aus einem zu 92 01o mit Benzol gesättigten Luftstrom 69 01o ihres Gewichts an Benzol aufgenommen. **) Frühere Zusatzpatente 386678, 393 865, 435 013 und 455 1 75 If you use z. B. a coal containing 19.8 per cent moisture, thus, from an air stream saturated to 92,010 with benzene, 69,010 becomes hers Weight of benzene added. **) Former additional patents 386678, 393 865, 435 013 and 455 1 75
