Description

Herstellung aktiver Kohle Es ist schon vorgeschlagen worden, gekörnte Kohle dadurch zu aktivieren, daß man die zunächst durch Einwirkenlassen von flüssigen Oxydationsmitteln, wie konzentrierte Salpetersäure, wäßrige Chlorkalklösung, Wasserstoffsuperoxydlösung, behandelte Kohle in Gegenwart beschränkter Mengen von Luft glüht. Es wurde gefunden, daß sich bei r,\nwendung dieses Verfahrens besondere Vorteile dadurch erzielen lassen, daß man an Stelle des flüssigen Oxydationsmittels, mit dem die Kohle vor Beginn des Glühprozesses zu tränken ist, Wasser benutzt und dann die feuchte Kohle unter beschränkter Luftzufuhr glüht. Auch auf diesem Wege erhält man ein sehr hochwertiges Material.Manufacture of active charcoal It has been proposed to use granular To activate charcoal by first allowing liquid to act Oxidizing agents such as concentrated nitric acid, aqueous chlorine lime solution, hydrogen peroxide solution, treated coal glows in the presence of limited amounts of air. It was found, that when using this process, particular advantages can be achieved by that one in place of the liquid oxidizing agent with which the coal before the beginning of the annealing process is to soak, using water and then adding the moist coal limited air supply glows. In this way, too, you get a very high quality one Material.
