摘要:针对催化裂化(FCC) 废催化剂细粉带来的环境污染和未开发利用的现状, 以此为原料合成了小晶粒 Y 型分子筛, 并采用 X
射线衍射、扫描电镜、29Si和27Al 固体核磁共振和激光粒度分析等技术对样品进行了表征. 结果表明, 以 FCC 废催化剂细粉为原
料可以合成粒径为 200 nm 左右的 Y 型分子筛, 且制备过程中原料的活化方法和导向剂对所得样品结构影响很大. 对原料采用碱
熔活化, 并在合成体系中加入导向剂, 所得 Y 型分子筛的相对结晶度提高, 比表面积增大, 粒度减小.

Abstract: Ultrafine Y zeolite was essfully prepared by a hydrothermal crystallization method using spent fluid catalytic cracking
catalyst powders as the raw material. The sample was characterized by X-ray diffraction, electron microscopy, 29Si and 27Al solid state
nuclear ic resonance, and particle size analysis. The results showed that the Y zeolite with particle size of 200 nm can be synthesized.
The structure of the Y zeolite is strongly influenced by the activation method and the amount of structure directing agent. In the presence of
