| Abstract | ||
| Experimental studies have been carried out on three types of crystalline zeolites which were prepared and used as supports catalysts. All were synthesized in the laboratory (ZSM-5, -11, and –23) with SiO2/Al2O3 ratio of 37, 86 and 94 respectively. The adsorption process was investigated to characterize the catalysts performance toward adsorption parameters (percent of extraction and distribution factor). The performance of catalysts was studied over the range of temperature (room, 50 and 80 ºC) for mono and di-valent ions respectively (H+, Li+, K+, Rb+, Cs+, Sr+2 and Ba+2). The prepared catalysts exhibited that the percent of extraction and distribution factor for both mono and di-valent ions (H+, Li+, K+, Rb+, Cs+, Sr+2, and Ba+2) used on adsorption increase with increasing temperature and also showed different to the framework structure and type of ions used. The maximum percent of extraction and distribution factor is in the order ZSM-11˃ ZSM-5˃ ZSM-23 respectively. | ||
