Notizen:
A method was developed for calculating the distributions of weight loss and temperature of spent activated carbon in a moving-bed regenerator in which the solid flow was regarded as being plug flow. A kinetic model developed earlier, which was based on regeneration consisting of many first-order reactions each with different frequency factors and different activation energies, was successfully applied to a design method for the regenerator. The flow pattern of the solid particles and heat transfer characteristics in a small moving bed were clarified experimentally, and the information obtained was used to calculate the distributions of weight loss of the spent carbon and temperature in the moving-bed regenerator by means of the design method. The calculated results were in fairly good agreement with the experimental data obtained in a small moving-bed regenerator. The adsorption capacity of the regenerated carbon was comparable to or greater than that of the virigin carbon.
