The adsorption behavior of benzene on dehydrated NaX and NaY zeolites has been investigated directly by 1H and 13C NMR measurements of the adsorbed benzene and indirectly by the combination of 129Xe NMR and isotherm measurements of the co-adsorbed xenon. Powdered zeolite samples of various Si/Al ratios and with varied adsorbate concentrations were investigated. Detailed macroscopic and microscopic adsorption phenomena of benzene in NaX and NaY zeolites, including the loading capacity, mobility, and sites of adsorption are presented in terms of measurements of NMR linewidths and chemical shifts.
