Abstract

 NANO ZEOLITE X WITH DIFFERENT SIO2/AL2O3 WAS SYNTHESIZED BY THE HYDROTHERMAL METHOD AND IONEXCHANGED WITH BARIUM AND ALSO CHARACTERIZED BY X-RAY DIFFRACTION, SCANNING ELECTRON MICROSCOPY (SEM) AND NITROGEN ADSORPTION. THE ADSORPTION PROCESS WAS CARRIED OUT IN A BREAKTHROUGH SYSTEM AT TEMPERATURE OF 120-160 OC AND PRESSURE OF 4-6 ATM. THE INFLUENCE OF NANO-ZEOLITE WATER CONTENT ON THE SEPARATION PROCESS WAS STUDIED. THE OPTIMIZATION OF ADSORPTION PROCESS WAS ALSO INVESTIGATED BY THE CHANGING OPERATION CONDITIONS. THE SELECTIVITY FACTOR OF PARA-XYLENE AND THE SATURATION ADSORPTION CAPACITIES OF ADSORBATES WERE DETERMINED. IT WAS OBSERVED THAT THE SELECTIVITY OF PARAXYLENE INCREASED BY BARIUM ION-EXCHANGING OF CATIONIC SITES IN NANO-ZEOLITE X AND THE SELECTIVITY FACTOR OF PARA-XYLENE/META-XYLENE, PARA -XYLENE/ORTHO-XYLENE AND PARA -XYLENE/ETHYLBENZENE IN THE OPTIMUM CONDITIONS WAS FOUND TO BE 7.191, 2.819 AND 3.745, RESPECTIVELY.
