The thermal frequency response technique (TFR) has been used to study the diffusion of benzene in NaX zeolite. The corrected diffusion coefficient is found to be independent of loading between 1.5 and 3.6 mol/cage at 406 K. It is in reasonable agreement with pulsed-field gradient NMR or quasi-elastic neutron scattering methods, but a large discrepancy is observed with the tracer zero length column (TZLC) technique. The activation energy for diffusion determined by TFR, 27 kJ/mol, is in accordance with the TZLC value, but substantially higher than the values reported from the other techniques. |
