Thermodynamics of Adsorption from Liquid Mixtures of Xylenes and p-Diethylbenzene on a Modified K—BaY Zeolite
Surface excess values for the adsorption of binary and ternary liquid mixtures, p-xylene/p-diethylbenzene, m-xylene/p-diethylbenzene, ethylbenzene/p-diethylbenzene, ethylbenzene/m-xylene and ethylbenzene/m-xylene/p-diethylbenzene on a modified K–BaY zeolite at 25°C are reported. Thermodynamic models...

description | Surface excess values for the adsorption of binary and ternary liquid mixtures, p-xylene/p-diethylbenzene, m-xylene/p-diethylbenzene, ethylbenzene/p-diethylbenzene, ethylbenzene/m-xylene and ethylbenzene/m-xylene/p-diethylbenzene on a modified K–BaY zeolite at 25°C are reported. Thermodynamic models for adsorption equilibrium have been applied to correlate the data. For data on binary systems, the characterized activity coefficients in the adsorbed phase and the adsorption equilibrium constant have been determined. Based on the method of Price and Danner, predictions of the adsorption equilibrium for the ternary systems have been carried out using parameters determined only from binary systems. For the ternary system ethylbenzene/m-xylene/p-diethylbenzene, the absolute average per cent deviations for the predicted values of the surface excess are 8.5% and 9.2% for ethylbenzene and m-xylene, respectively. Accordingly, the correlations obtained can be used to calculate the adsorption equilibrium for binary and ternary systems consisting of p-xylene, m-xylene, ethylbenzene and p-diethylbenzene on a modified K–BaY zeolite at 25°C. |
