✦ Synopsis

4 is shown by a simplified theoretical analysis of the heat dissipation from the adsorbent particles during the measurement of sorption kinetics that even a small change in the adsorbent temperature can cause significant error in the calculation of the sorption diffusivity by the assumption of isothermal behavior. Thus, the use of a differential step change in the adsorbate loading during the kinetic measurements, which produces a small change in the adsorbent temperature, may not assure correct interpretation of the data by the isothermal models. * The average crystal size In the zeollte (r) is assumed to be 1Okm * Extrapolated values at the limit of zero surface coverage
