Kinetics of Adsorption in a Column—Chromatographic Analysis

Using this theory, equilibrium and rate parameters of the system can be determined from laboratory experiments, and most of the parameters are independent of the dimensions of the equipment, so the results from the laboratory-scale apparatus are generally applicable to the commercial design of the adsorbers. In this case, the nature and operation of the laboratory apparatus are the same as for conventional chromatographic experiments. However rigorous treatment of the effluent peak becomes necessary for the extraction of the parameters from the response data. 

In a fixed bed of adsorbent particles, the adsorbate-containing input pulse is influenced by several mass transport steps both in the gas in the porous adsorbent particles. It is difficult to extract reliable values for the rate parameters for all of these steps from the shape of a single effluent peak. Therefore, pulse-response experiments at different values 

the general theory is presented for a bed of monodisperse particles, followed by illustrations of the use of specific data in evaluating particular rate parameters. Application of the method to more complex systems such as a bed of bi-disperse particles and a bed of catalyst particles where surface reaction occurs is also discussed. 

Reference is made as well to application of the theory developed for linear systems to non-linear isotherm systems.
