Description

Herstellung einer aktiven Kohle Es ist bekannt. daß man aktive Kohle aus geei gneten, beim Erhitzen Kohlenstoff liefernden Substanzen, z. B. Holz, Torf, Braunkohle u. a., durch Erhitzen mit verschiedenen Beimengungen oder unter Mitwirkung bestimmter Gase herstellen kann. Durch Erhitzen dieser Stoffe für sich allein wird im allgemeinen keine oder doch nur eine geringfügige Aktivierung erreicht.Production of an active carbon It is known. that you have active coal from suitable substances that produce carbon when heated, e.g. B. wood, peat, Brown coal, among other things, by heating with various admixtures or with assistance can produce certain gases. By heating these substances on their own it becomes generally no or only a slight activation is achieved.

Es wurde nun gefunden, daß man bei Verwendung einer bestimmten Art von Braunkohle, nämlich einer Kohle, die, abgesehen von den Aschebestandteilen, ganz oder zum größten Teil aus in kalten verdünnten wäßrigen Lösungen von Alkalien oder Ammoniak löslichen Huminsubstanzen (Huminsäuren) besteht, durch einfaches Erhitzen auf helle Rotglut --- ohne Anwendung besonderer Aktivi.erungsmittel - ohne weiteres eine namentlich für katalytische Zwecke- hervorragend geeignete aktive Kohle erhält, deren Wirksamkeit durch die übliche Nachbehandlung mit Säure und Wasser noch gesteigert werden kann. Kohle der oben beschriebenen Art wird z. B. von den Wellmitzer Braunkohlenwerken (Niederlausitz) unter der Bezeichnung Humuskohle in den Handel gebracht. Beispiel In Körnung von 2 bis 3 mm gebrachte Welhnitzer Humuskohle wird bis auf etwa r ooo° oder darüber erhitzt. Die vorher ziemlich lockere Kohle liegt nun in fester körniger Form vor und kann leicht von löslichen Bestandteilen durch Waschen mit Salzsäure befreit werden. Sie ist z. B. zur katalytischen Oxydation von Schwefelwasserstoff gut brauchbar.It has now been found that when using a certain type of lignite, namely a coal that, apart from the ash components, wholly or for the most part from in cold, dilute aqueous solutions of alkalis or ammonia-soluble humic substances (humic acids), simply by heating to bright red heat --- without the use of special activators - without further ado receives an active charcoal that is particularly suitable for catalytic purposes, their effectiveness is further increased by the usual aftertreatment with acid and water can be. Coal of the type described above is z. B. from the Wellmitzer lignite works (Niederlausitz) marketed under the name humus coal. example Welhnitzer humus charcoal with a grain size of 2 to 3 mm is reduced to about r ooo ° or heated above. The previously rather loose coal is now in a solid, granular form Form before and can be easily removed from soluble components by washing with hydrochloric acid to be freed. She is z. B. for the catalytic oxidation of hydrogen sulfide good usable.
