摘要
Binary gas mixture adsorption equilibrium data for the ethylene-carbon dioxide system were obtained for cation exchanged forms of ZSM5 (Li^+, Na^+, K^+, Rb^+, Mg^(+2), Ca^(+2), Sr^(+2), and Ba^(+2)) for the gas phase CO_2 mole fracion of 0.766 at 308K and 101. 3kPa. The experimental adsorption phase diagrams were obtained for CO_2-C_2H_4 on NaZSM5 and MgZSM5. Single component adsorption isotherms for CO_2 and C_2H_4 were also obtained for these two zeolites. The single component data were used to obtain parameters derived in the vacancy solution model (VSM) and the statistical thermodynamic model(STM). These parameters were, in turn, used to predict binary mixture isotherms for these two zeolites. The agreement between experimental data and predicted value is generally good.
Binary gas mixture adsorption equilibrium data for the ethylene-carbon dioxide system were obtained for cation exchanged forms of ZSM5 (Li<sup>+</sup>, Na<sup>+</sup>, K<sup>+</sup>, Rb<sup>+</sup>, Mg<sup>+2</sup>, Ca<sup>+2</sup>, Sr<sup>+2</sup>, and Ba<sup>+2</sup>) for the gas phase CO<sub>2</sub> mole fracion of 0.766 at 308K and 101. 3kPa. The experimental adsorption phase diagrams were obtained for CO<sub>2</sub>-C<sub>2</sub>H<sub>4</sub> on NaZSM5 and MgZSM5. Single component adsorption isotherms for CO<sub>2</sub> and C<sub>2</sub>H<sub>4</sub> were also obtained for these two zeolites. The single component data were used to obtain parameters derived in the vacancy solution model （VSM） and the statistical thermodynamic model（STM）. These parameters were, in turn, used to predict binary mixture isotherms for these two zeolites. The agreement between experimental data and predicted value is generally good.
