摘要：

The π-complexation adsorbent AgNO3/γ-Al2O3 was prepared from AgNO3 supported on γ-Al2O3 by the method of impregnation.The adsorbent is used for ethylene-ethane separation.The monolayer dispersion of AgNO3 on γ-Al2O3 was characterized with BET and XRD, and the maximum monolayer dispersion capacity of AgNO3 on γ-Al2O3 was calculated by XRD quantitative phase analysis.The adsorption equilibrium isotherms of ethylene and ethane on this adsorbent were measured at 38℃.The adsorption equilibrium data of ethylene and ethane could be properly fitted by the Langmuir-Freundlich model.The π-complexation adsorbent AgNO3/γ-Al2O3 had high equilibrium selectivity of ethylene,and the selective adsorption ratio of ethylene to ethane at 38℃ and 100 kPa was 10.1, showing its potential for commercial application.
