Abstract

Recently reported diffusivity data for N2, CH4 and Kr in 4A zeolite pelleted adsorbent are compared with earlier data for the same sorbates in several different 4A samples. It is shown that, although there are large differences in diffusivity between the different adsorbent samples the activation energies are essentially constant. The data can be reconciled if it is assumed that the samples contain different fractions of “open” windows as a result of non-ideal distribution of the Na+ cations.
