Preparation of Binder-free Utrafine ZSM-5 Zeolite Monoliths by Vapor-phase Transformation Method
汽相转化法制备无粘结剂小晶粒 ZSM-5沸石

Using vapor-phase transformation method, binder-free monoliths of ultrafine ZSM-5 zeolite crystals were prepared by conversion of the preformed bodies of diatomite and silica sol, which mixed with some zeolite seeding directors. The tiny zeolite crystals and units in the seeding directors inducted the conversion of the alumino-silicalite raw materials into intergrown ZSM-5 zeolites, which resulted in binder-free zeolite monoliths. The prepared materials possess enriched porosity, high surface area, good mechanical strength and tunable acidity which can be verified by the characterization. The products have promising applications in catalyst and adsorbent.
