Herkömmliche Verfahren sehen eine Verschwelung der Trägermaterialien mit der Aktivkohle vor. Beispielsweise erfolgt in einem Drehrohrofen, wie er bislang zur Angewendung gelangt, eine Hitzezufuhr an die Außenoberfläche der Aktivkohle, wodurch die Poren der Aktivkohle verklebt werden und die Leistungsfähigkeit der Aktivkohle eine Einbuße erleidet.conventional Procedures see a smoldering of the support materials with the activated carbon in front. For example, in a rotary kiln, How he has been applied so far, a heat input to the outer surface the activated carbon, whereby the pores of the activated carbon are bonded and the efficiency of the activated carbon a loss suffers.
Bei
