Description

Verfahren zur Abscheidung organischer Gase bzw. Dämpfe.Process for separating organic gases or vapors.

Zusatz zum Patent 3I0092. Addition to patent 3I0092.

Durch das Hauptpatent ist die Abscheidung von organischen Gasen bzw. von vergasten organischen Körpern aus ihren Gemischen mit Luft oder anderen schwer bzw. nicht absorbierbaren Gasen, wie Wasserstoff, geschützt. Das Verfahren besteht darin, daß solche Gemische mit besonders poröser Kohle, wie sie nach dem Verfahren der Patentschrift 290656 hergestellt werden kann, behandelt und die von der Kohle afl} sorl) ierten organischen Körper wieder mit Hilfe von Wasserdampf in der Hitze ausgetrieheu werden. The main patent is the separation of organic gases or of gasified organic bodies from their mixtures with air or other difficult or non-absorbable gases such as hydrogen. The procedure persists in that such mixtures with particularly porous coal, as they are after the process of patent 290656 can be manufactured and treated by the coal Afl} sorl) ized organic bodies again with the help of steam in the heat to be expelled.

Es wurde nun die bemerkenswerte Beobachtung gemacht, daß die Austreibung der absorbierten Gase oder Dämpfe anstatt mit Wasserdampf auch mit Gasen oder Gasgemischen bewerkstelligt werden karl. Diese Ausführungsweise des Hauptpatents hat in vieler Beziehung große Vorteile. Dieses Verfahren gestattet z. B. bei Verwendung derselben Gasart, aus der die absorbierten Bestandteile vorher entfernt worden sind, ein höher prozentiges Gasgemisch herzustellen, als es vorher vorhanden war. Man kann aber auch eine andere Gasart zum Austreiben wählen, z. B. eine solche, die auf irgendeine Weise leicht aus dem Gasgemisch wieder entfernt werden kann, so daß der vorher durch die Kohle absorbierte Bestandteil allein übrigbleibt. Als solches Gas kommt z. 3. The remarkable observation has now been made that the expulsion of the absorbed gases or vapors with gases or gas mixtures instead of with water vapor be accomplished karl. This embodiment of the main patent has in many Relationship great benefits. This method allows e.g. B. when using the same The type of gas from which the absorbed components have been previously removed is higher produce percent gas mixture than it was before. But you can also choose another type of gas for expulsion, e.g. B. one that is based on any Way can easily be removed from the gas mixture again, so that the previously through the carbon absorbed component alone remains. As such a gas comes z. 3.

Kohlensäure in Frage, die dann durch Verflüssigung oder auf chemischem Wege, z. B. durch Bindung an Kalk, wieder entfernt werden kann.Carbonic acid in question, then by liquefaction or on chemical Ways, e.g. B. can be removed again by binding to lime.

Eine für gewisse Zwecke der Technik sehr vorteilhafte Ausführung dieses Verfahrens besteht darin, daß man mehrere auswechsel- oder umschaltbare Kohlebehälter verwendet. Leitet man z. 3. die Dämpfe einer leichtflüchtigen Flüssigkeit mit einem Überschuß von Wasserstoff zwecks Reduktion über einen Katalysator, so wird in den meisten Fällen der austretende Wasserstoff noch unangegriffene Dämpfe mit sich führen, die wegen der großen Verdünnung selbst durch 4ie besten Kühlvorrichtungen nicht vollständig abgeschieden werden können.A very advantageous embodiment of this for certain technical purposes The method consists in having several exchangeable or switchable charcoal containers used. If one leads z. 3. the vapors of a highly volatile liquid with a Excess of hydrogen for the purpose of reduction over a catalyst, so is in the In most cases, the escaping hydrogen still carries unaffected vapors with it, not because of the great dilution even by the best cooling devices can be completely deposited.

Entzieht man diese Dämpfe dem Wasserstoff durch vorgelegte Kohle, so kann man, nachdem die Kohle gesättigt ist, sie so schalten, daß reiner Wasserstoff durchtritt und die Dämpfe nunmehr wieder dem Katalysator zugeführt werden. Man erreicht auf diese Weise bei Verwendung von zwei oder mehr umschaltbaren Kohlebehältern einen Kreislauf, der ein ununterbrochenes Arbeiten ohne irgendeinen Verlust an Substanz ermöglicht.If these vapors are withdrawn from the hydrogen by charging coal, so, after the carbon is saturated, it can be switched so that it is pure hydrogen passes and the vapors are now fed back to the catalyst. One achieves in this way one when using two or more switchable charcoal containers Cycle that allows continuous work without any loss of substance enables.

Man kann natürlich auch eine nach dem Verfahren des Patents 30776I behandelte Kohle benutzen. One can, of course, also use one according to the method of patent 30776I use treated charcoal.

PATENT-ANSPRÜCHE: I. Abänderung des durch das Hauptpatent geschützten Verfahrens, um organische Gase bzw. vergaste organische Körper aus ihren Gemischen mit Luft oder anderen schwer bzw. nicht absorbierbaren Gasen, wie Wasserstoff, abzuscheiden, darin bestehend, daß man zur Austreibung der Gase bzw. Dämpfe an Stelle von Wasserdampf hier andere Gase oder Gasgemische bei beliebigen Temperaturen benutzt. PATENT CLAIMS: I. Modification of that protected by the main patent Process to produce organic gases or gasified organic bodies from their mixtures to be separated with air or other difficult or non-absorbable gases such as hydrogen, consisting in that one expels the gases or vapors instead of water vapor other gases or gas mixtures used here at any temperature.
