Adsorption isotherms of CFC-113 on activated carbon were determined at various temperature (298K, 313K, 343K, 373K, 393K). The isotherms were predicted by Langmuir model fairly well and the results were used to simulate the adsorption and desorption experimental data. Fixed bed adsorption experiments were performed, varying flow rate, concentration and temperature. Mass transfer coefficients were estimated comparing constant pattern solution with experimental breakthrough curves. Fixed bed adsorption experiments were made, varying temperature and flow rate. A nonequilibrium, nonadiabatic model was used to simulate experimental data. In the model, mass transfer rate was expressed by linear driving force with mass transfer coefficients varying with temperature and thermal equilibrium between adsorbent and gas phase was used.
