摘　　要： 在酸性水热条件下,通过附晶生长法合成Y-Beta/MCM-41复合分子筛,并对其结构、形貌、水热稳定性及催化性能进行研究。结果表明,合成的Y-Beta/MCM-41复合分子筛比表面积高和水热稳定性好,对α-甲基萘的催化裂解性能明显优于机械混合物,表现出良好的催化性能。 Y-Beta/MCM-41 composite molecular sieve was synthesized by overgrowth method in acid system. The structure, morphology, hydrothermal stability and catalytic properties of the material were studied. The experimental results showed that the as -synthesized Y-Beta/MCM-41 composite molecu- lar sieve possessed high specific surface area, good thermal stability and catalytic cracking performance of α-methylnaphthalene, which was superior to that of mechanical mixture.
