N2 - An isothermal-isobaric column dynamic test apparatus was built to measure equilibrium adsorption isotherms of pure N2 and O2 and their binary mixtures at 0, 30, and 65 °C in the pressure range of 0-6 atm on LiLSX zeolite. The data successfully passed an integral and a differential thermodynamic consistency test between pure and binary gas isotherms. The binary selectivities of N2 over O2 were functions of the gas-phase mole fraction and pressure, and the pure gas isosteric heats of adsorption decreased with increased loadings. Thus, the adsorbent was energetically heterogeneous for both gases. The degree of heterogeneity for N2 was larger than that for O2.
