摘要：

Adsorption isotherms of CO2 are volumetrically measured at temperatures close to ambient (30, 35, 40 and 45 degrees C) over MgO impregnated NaY zeolites, in order to highlight the effect of MgO impregnation rate on the adsorbed quantities. XRD analysis displays a good preservation of the zeolitic structure after impregnation. Textural parameters are determined by both adsorption-desorption isotherms of N-2 at -196 degrees C and adsorption isotherms of CO2 at 30 degrees C. The result of the impregnation rate effect shows that 2% of MgO seems to be the better rate for the capture of CO2. This is confirmed by the evolution of isosteric heats, which reveals a high strength interaction and heterogeneity of zeolitic sites adsorption. The modeling of CO2 adsorption isotherms based on various isotherms (single-site Langmuir, dual-site Langmuir, multi-site Langmuir, Sips, Jensen-Seaton, Toth, UNILAN and Freundlich) highlights a good correlation with all models based on the hypothesis of heterogeneity of adsorption sites.
