Abstract
A survey is given on the possibilities of pulsed field gradient (PFG) NMR to study molecular diffusion in beds of microporous adsorbent part icles (zeolite crystallites). Depending on the given adsorbate-adsorbe nt system, the PFG NMR data on intracrystalline diffusion are both in agreement and disagreement with the results of uptake measurements. Tw o novel routes to unveil the origin of such discrepancies are describe d.
