| Abstract: | A method that enables the calculation of adsorption isotherms in wide temperature range basi cally from a few TemperatureProgrammed Desorption （TPD） experiments is introduced. In the method, a transient kinetic model is established based on quasiequilibrium adsorption/desorption between the gas phase and the adsorbent for the rapid reabsorption during TPD. The model is numerically solved to fit to experimen tal TPD data by adjustment of the equilibrium parameters. Hence adsorption isotherm is calculated. This method was applied to study the adsorption isotherms of nhexane on HZSM5, 5A, HY and 13X zeolites. The results were found in good agreement with literature reports. |
