The diffusion and adsorption of several C6 hydrocarbons in small commercial silicalite crystals was studied using chromatographic methods and a wall-coated capillary column (tables 42 and 43). Both the kinetic and equilibrium data were generally consistent with the results of earlier gravimetric measurements involving large laboratory-synthesized crystals. This confirmed the validity of the wall-coated column technique for measuring diffusion, and the essential similarity in the diffusional behaviors of large and small silicalite crystals.
