摘要
Two NMR techniques have been developed to study the diffusion of hydrocarbons in zeolites. Xe-129 NMR of adsorbed xenon in which xenon is used to probe the concentration of a co-adsorbed hydrocarbon and H-1 NMR imaging which gives directly the concentration profile of a hydrocarbon in a zeolite along one or more directions.
