Measurement of Diffusion in Zeolites—A Never Ending Challenge?

  • Published:
Adsorption Aims and scope Submit manuscript

Abstract

A review is given on the main problems associated with the determination and interpretation of molecular diffusion in zeolites. It is shown that the diffusivities may most decisively depend on the relevant space and time scales of observation, as well as on the physical state under which the measurements are carried out. Special emphasis is given to the microscopic techniques and their most recent evidence on the existence of transport resistances distributed over the intracrystalline space.
