Abstract

The ZLC technique is a powerful technique for the measurement of diffusion in nanoporous materials using mg quantities of a sample. Questions remain on whether the measured properties are representative of larger samples. A methodology has been developed to carry out single pellet experiments to determine average properties and variability of equilibrium and kinetic properties. To demonstrate the approach, n-pentane on HISIV3000 extrudates was used as the test system, which was shown to be macropore diffusion controlled. Results on nine pellets provided average values showing a perfect match to breakthrough column experiments with a sample two orders of magnitudes larger.
