| Abstract: | The synthesis of X-type zeolite membrane was studied in the hydrothermal conditions. A secondary growth method with the pre-seed step was used by choosing the stainless steel net as the support. Different reaction conditions were adjusted for the preparation of X-type zeolite membrane, such as the quantity of water, alkalinity, Si/Al ratio and the reaction time. Scanning electron microscopy technique was employed to observe the morphology of X-type zeolite membranes. Finally, the best synthesis conditions were found after the comparison and analysis of these results, better morphology without obvious defects X-type zeolite membranes were then synthesized. |
