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.
