Adsorption Equilibrium of Xylene Isomers and p-Diethylbenzene in the Liquid Phase on a Y Zeolite
The saturated adsorptive capacity, adsorption equilibrium constant and adsorption isotherms of p-xylene, m-xylene, ethylbenzene (EB) and p-diethylbenzene (PDEB) on a K–BaY zeolite with n-heptane as the solvent have been studied at 25°C. The adsorption isotherms of the six binary pairs of these solut...

| description | The saturated adsorptive capacity, adsorption equilibrium constant and adsorption isotherms of p-xylene, m-xylene, ethylbenzene (EB) and p-diethylbenzene (PDEB) on a K–BaY zeolite with n-heptane as the solvent have been studied at 25°C. The adsorption isotherms of the six binary pairs of these solutes with n-heptane as the solvent have also been determined at 25°C. The data cover a concentration range of xylene isomers from 0.05–0.3 mmol/ml. The molar adsorption capacity of the K–BaY zeolite for the different sorbates was found to be in the order: p-xylene > EB > m-xylene ≈ PDEB. PDEB is normally used as the desorbent for the Parex process. Three types of isotherm model, i.e. Langmuir, Freundlich and Langmuir–Freundlich, have been used to fit the data. The results indicate that the Langmuir–Freundlich isotherm provides a reasonable representation of the equilibrium data for the xylene isomers on a K–BaY zeolite. |
