摘要：

The sorption and transport properties of benzene on dehydrated NaX and NaY zeolites have been investigated directly by H-1 and C-13 NMR measurements of the adsorbed benzene and probed indirectly by Xe-129 NMR of the coadsorbed xenon. Dehydrated NaX and NaY zeolite adsorbate samples containing various adsorbate concentrations and having various sample bed configurations, which were subjected to different preparatory and experimental conditions, have been examined. Thermal treatment at a temperature (>250-degrees-C) much greater than the boiling point of bulk benzene (80-degrees-C) for an extended period of several hours is indispensable to ensure a homogeneous benzene distribution within the supercages of the faujasite-type zeolites.
