Abstract (EN): Powder, agglomerates and tablets of the microporous zirconium (IV) terephthalate Metal-organic framework UiO-66 were evaluated for selective adsorption and separation of xylene isomers and ethylbenzene in liquid phase using n-heptane as eluent. Pulse experiments, performed at 313 K in presence of n-heptane, revealed the o-xylene preference of this material, further confirmed by binary and multi-component breakthrough experiments in the presence of m-, p-xylene, and ethylbenzene. The shaping of the material as tablets did not significantly change its selectivity towards the o-xylene isomer despite a loss in capacity. The binary and multicomponent equilibrium data of the xylene isomers and ethylbenzene was well modeled by a Dual Langmuir model. The simulations of the breakthrough and reverse breakthrough experiments were performed in the three materials, presenting good agreement between the simulation and experimental results.
