A new mass transfer model for cyclic adsorption and desorption

This article presents a new mass transfer model which describes mass transf er rates in a spherical particle where cyclic adsorption and desorption occ ur. The parameters in the model equation were determined by matching the ex act numerical solution to the prediction of this rate law over a range of c ycle times. The maximum error was found to be 4.3%. Since the parameters ar e independent of cycle time, this model equation can be generally used for cyclic adsorption and desorption process regardless of the cycle time and c ycle configuration.
