Notes:
The kinetics of the thermal regeneration of activated carbons used in the waste water treatment was analyzed on the basis of a model that the regeneration reaction consists of a set of many first-order reactions each of which has different activation energy and frequency factor. The frequency factors were correlated approximately by a function of the activation energy.The difference in the activation energy was represented by a distribution curve which was obtained by analyzing the thermogravimetric curve (TG curve) measured under a constant heating rate. The weight loss during the regeneration reaction under complicated heating conditions was well predicted by use of the distribution curve determined by the proposed method. This method describing the kinetics of the thermal regeneration may be applied to the design of reactors regenerating spent carbons.
