Abstract
259,616. Verein fur Chemische Industrie Akt.-Ges., (Assignees of K³chler, E.). Oct. 12, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Charcoal.-Carbon is activated or spent activated carbon is re-activated by treating it at elevated temperature with a stream of dry or moist gas containing free oxygen, such as air whereby partial oxidation occurs. The gas may be supplied under pressure or by means of suction, intermittently or continuously. Preferably the carbon to be treated is in granular form and the treatment is carried out in tubes having permeable walls which may be made of iron besides clay and fire-clay, whereby the products of combustion are readily removed and coking thus prevented. The speed of the stream of gas, the time of treatment, the thickness of the layer of carbon and the size of its granules may be varied. In one example, carbon is activated in an iron tube by means of a gas containing oxygen and in a second example spent carbon originally prepared by means of zinc chloride is reactivated.
