New experimental data are reported for equilibrium adsorption isotherm and mass transfer of pure argon on a sample of pelletized lithium-exchanged low silica X (LiLSX) zeolite. Model analysis of the data indicate that the zeolite behaved like a nearly homogeneous adsorbent for Ar adsorption while it exhibited substantial heterogeneity for adsorption of N2 and milder heterogeneity for adsorption of O2. The overall mass transfer coefficient for Ar adsorption was comparable in magnitude with those of N2 and O2. The coefficient increased with increasing pressure and decreased with increasing temperature like those for N2 and O2. A large skin resistance at the adsorbent particle surface was observed for Ar mass transfer like that for adsorption of O2 and N2.
