摘要：

Xe-129 NMR has been used to study the diffusion of adsorbed xenon between zeolite crystallites. This intercrystallite xenon diffusion depends much upon zeolite structure. Other factors such as zeolite dilution, compression and experiment temperature can also greatly influence the xenon NMR results. Details of these effects are discussed in the present work. This information is of vital importance from the point of view of the application of the xenon NMR technique to the study of industrial zeolitic catalysts.
