Study of the Effects of Si/Al Ratio and Operating Conditions in Hydrothermal Dealumination of Y Zeolite
NaY zeolites with different framework Si/Al ratios were synthesized via hydrothermal technique. Structural characteristics of the synthesized zeolites were determined by using XRD, XRF, SEM, BET analyses. The effects of operating conditions of hydrothermal dealumination, i.e. time, temperature and partial pressure of water vapor on dealumination of the Y zeolites framework and their structure were investigated via XRD and BET analyses. According to the experiments, hydrothermal dealumination of the Y zeolite with Si/Al=1.69 was not successful while it was satisfactorily performed for the other one with Si/Al=2.44
