Abstract: A novel method for the preparation of NaY molecular sieve by using a Si-Al gel with special composition as the directing agent was presented. The as-synthesized NaY molecular sieve was characterized with SEM, XRD and BET. The NaY molecular sieve had a particle size of approximately 2μm, n(SiO2)/n(Al2O3) of 3.28, crystallinity of 90% and specific surface area of 703 m2/g. Except the crystallization process, the synthesis of the NaY molecular sieve was conducted at room temperature under mild and controllable reaction conditions.

摘要： 报道了以具有独特组成的硅铝凝胶为导向剂制备NaY分子筛的方法。所合成的NaY分子筛用SEM、XRD和BET等进行了表征，结果表明，该NaY分子筛粒径2 μm左右，硅铝比n(SiO₂)/n(Al₂O₃)为3.28，结晶度90%，比表面积703 m²/g。除晶化过程外，该合成NaY分子筛的工艺过程均在室温下进行，具有反应条件温和，易于调控的特点。
