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.
Abstract
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 molecular sieve possessed high specific surface area,good thermal stability and catalytic cracking performance of α-methylnaphthalene,which was superior to that of mechanical mixture.
