The tracer zero-length column (ZLC) method has been employed to study the diffusion of toluene in one-dimensional ZSM-12 and SAPO-5 zeolites. A significant deviation in the shape of the measured tracer exchange curves from monoexponential behavior was observed for toluene diffusion in both adsorbents in the limit of long-time asymptotes. In contrast,(More)
With growing interest for the use of one-dimensional (1-D) zeolites in separation and reaction processes, the need to understand diffusion and transport properties of molecules within the channels of these materials is becoming more eminent. The mechanism used to describe passage of molecules inside narrow 1-D micropores is called single-file diffusion.(More)
