Description

Verfahren zur Absorption von Gasen und Dämpfen und Ausführung katalytischer Reaktionen.Process for absorption of gases and vapors and execution of catalytic Reactions.

Claims (1)

Sogenannte aktive Kohle, wie sie beispielsweise nach dem deutschen Patent 290656 erhalten wird, kann als Katalysator bei der Ausfiihrung chemischer Reaktionen mit Vorteil Verwendung finden. Desgleichen besitzt solche Kohle die #igenschaft, Gase und Dämpfe zu absorbieren, und man kann sie auf Grund dieser Eigenschaft zur Abscheidung von Gase' und Dämpfen in ihrer Gesamtheit oder zur Trennung von Gemischen von Gasen und Dämpfen verwenden. So-called active coal, as it is for example after the German Patent 290656 is obtained, can be used as a catalyst in the execution of chemical Find reactions with advantage. Likewise, such coal has the property To absorb gases and vapors, and you can use them because of this property Separation of gases and vapors in their entirety or for the separation of mixtures use of gases and vapors. Es wurde nun gefunden, daß für beide Verwendungszwecke solche aktive Kohle, wie sie nach der deutschen Patentschrift 371691 erhältlich ist, mit besonderem Vorteil verwenilet werden kaml. Diese Kohle besitzt nämlich sowohl eine besonders große Härte, wodurch das Zerfallen und Verstäuben in besonderem Maße vermieden und der Durchlaß der Gase und Dämpfe gewährleistet wird, als auch hat diese Kohle die Eigenschaft, im Vergleich zu an-(iicrer aktiver Kohle, sich besonders schwer zu entzünden, eine Eigenschaft, die die Handhaltung der für beide obengenannte Zwecke geeigneten Kohlen, sei es der bei der Reaktion erhitzten oder der nach der Absorption und NViederausscheidung der Gase und Dämpfe zu trocknenden Kohle, besonders erleichtert. It has now been found that for both uses such active Coal, as it is available according to German Patent 371691, with special Advantage to be used caml. This coal has both a special great hardness, which prevents disintegration and dusting to a particular degree the passage of gases and vapors is guaranteed, as well as this coal has the Property, in comparison with other active charcoal, is particularly difficult to obtain ignite, a property that affects the hand position for both of the above purposes suitable coals, be it those heated during the reaction or those after absorption and N precipitation of the gases and vapors to be dried coal, particularly facilitated. In der britischen Patentschrift 166229 ist ein Verfahren zur Herstellung von Entfärbungskohle beschrieben, nach welchem unter anrlerem eine Behandlung der Kohle mit wäßriger Phosphorsäure und danach die Verwendung der so behandelten Kohle unmittelbar im feuchten Zustande für Entfärbungszwecke erfolgen soll. Aus einer etwaigen besseren NVirksamkeit der so behandelten Kohle für Entfärbungszxvecke kann nicht ohne weiteres; auf eine höhere Absorptionswirkung gegenüber Gasen und Dämpfen und auf eine stärkere katalytische Wirkung im Sinne der vorliegenden Erfindung geschlossen werden, insbesondere aber kommen bei der dort erhaltenen feuchten Kohle die im vorhergehenden Absatz aufgeführten besonderen Effekte der großen Härte und Unverbrennlickeit hie überhaupt nicht in Betracht. In British Patent 166229 there is a method of manufacture of decolorizing charcoal, according to which, below, a treatment of the Coal with aqueous phosphoric acid and then the use of the so treated coal should take place immediately in the moist state for discoloration purposes. From a any better effectiveness of the carbon treated in this way for decolorizing purposes not without further ado; to a higher absorption effect against gases and vapors and inferred a stronger catalytic effect within the meaning of the present invention are, but especially in the case of the moist coal obtained there, those in the foregoing occur Paragraph listed special effects of the great hardness and incombustibility called not considered at all. PATENT-ANSPRUCH : Verfahren zur Absorption von Gase und Dämpfen und Ausführung katalytischer Reaktionen mit Hilfe von aktiver Kohle, gekennzeichnet durch die Verwendung solcher aktiver Kohle, wie sie nach dem Verfahren der deutschen Patentschrift 371691 erhalten wird. PATENT CLAIM: Process for the absorption of gases and vapors and Carrying out catalytic reactions with the help of active charcoal, marked through the use of such active charcoal as they are after the method of the German Patent 371691 is obtained. @) Von dem Patentsucher sind als Erfinder angegeben worden:@) The patent seeker indicated the following as the inventor:
