| 摘 要： | 采用两种不同的水热晶化法合成Beta-Y复合分子筛,并采用XRD、SEM-EDS、FT-IR、N2 吸附-脱附技术对其进行表征。结果表明,以Beta分子筛为唯一硅源合成的sample A具有Y和Beta分子筛两种晶型结构,为机械混合形式;而以Beta分子筛母液为前躯体合成的sample B为核壳结构的复合分子筛,具有Y和Beta分子筛两种晶型结构,其核相为Beta分子筛,壳层为Y型分子筛,其晶体中具有介孔结构,并且介孔孔径比较集中。

| Abstract: | Beta-Y composite zeolites were prepared by two methods and were characterized by XRD,SEM,FT-IR and N2 adsorption.The results indicated that sample A synthesized with Beta zeolite as unique silica source is a composite zeolite of Beta and Y in a mechanical mixed mode,while sample B synthesized with mother liquor of Beta zeolite as precursors is a composite zeolites with core-shell structure.The core-shell Beta-Y composite zeolite(sample B) owns crystal lattices of Y zeolite as shell and Beta zeolite as core and is provided with centralized mesopore. |
