Résumé :
|
A novel method based on Fourier transform infrared spectroscopy (FTIR) is applied to study sorption and sorption kinetics of p-xylene in ZSM-5-type zeolites as a single component and in a binary-component system, in the presence of benzene under conditions close to those of a catalytic run. From the change of intensities of IR bands characteristic for the adsorbates, diffusivities of p-xylene in the single-component system as well as in the binary-component system are determined at various temperatures and loadings.
