Abstract

Methods for synthesizing pelletized ZSM-5 zeolites in the H-form with a high degree of crystallinity and a micro–meso–macroporous structure using synthetic amorphous aluminosilicates synthesized by precipitation from aqueous solutions of sodium silicate and aluminum sulfate or by sol–gel synthesis using tetraethyl orthosilicate and aluminum nitrate have been described. It has been shown that the nature of amorphous aluminosilicate affects the crystallization conditions for the pelletized zeolite and the morphology and degree of dispersion for the resulting ZSM-5 zeolite crystals.
