Diffusion Obstacles Inside the ZSM-5 Framework by Pulsed-Field Gradient NMR

Location of Diffusion Obstacles Inside the ZSM-5 Framework by Pulsed-Field Gradient NMR 

For a number of adsorbate-adsorbent systems it has been found that the intracrystalline self-diffusion of a highly mobile component is drastically reduced by the presence of a second, strongly coadsorbed component. By combining these self-diffusion measurements with a computer simulation of 

Molecular Self-Diffusion of Methane Adsorbed on ZSM-5 Containing Coadsorbed Benzene 

Self-Diffusion in HZSM-5 Containing Chemisorbed N Bases 

Chemisorption of N compounds leads to a significant reduction of the self-diffusion coefficients of methane. This effect becomes more pronounced with increasing amounts of chemisorbed N bases. Obviously, with
