An analysis of new and available data on the adsorption of n-pentane, n-hexane, 3-methylpentane, p-xylene, toluene, and isopentane in ZMS-5 zeolites suggested that the reactant molecules enter the ZSM-5 catalyst essentially by its sinusoidal channels and that the isoaliphatic and aromatic products diffuse preferentially in the linear and elliptical channels. Conversion occurs at the channel intersection. These observations account for the absence of major counterdiffusion effects in ZSM-5 zeolites.
