Abstract

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.
