英文摘要	adsorption equilibrium, thermodynamics, and kinetics of ch4, n-2, and co2 were investigated by volumetric-chromatographic and inverse gas chromatographic (igc) methods on the al-bdc mof. the binary adsorption data from the volumetric-chromatographic experiments represents that the al-bdc mof has a high co2/ch4 selectivity ca. 11 and a ch4/n-2 selectivity ca. 4.3 at 303 k, and appears to be a good candidate for the ch4 separation. the initial adsorption heats of ch4, n-2, and co2 on the al-bdc mof were determined to be 15.3, 11.5, and 32.2 kjmol(-1) by igc method, respectively. moreover, the micropore diffusivities of n-2, ch4 and co2 in the al-bdc mof at 303 k were also estimated to be 1.58 x 10(-7) cm(2)/s, 7.04 x 10(-8) cm(2)/s, and 3.95 x 10(-9) cm(2)/s, respectively. the results indicate that micropores play a crucial role in the adsorptive separation of the ch4/n-2 and ch4/co2 mixtures, and the igc method is a validity manner to estimate the thermodynamic and kinetic parameters of mof adsorbents.
