Synthesis and physicochemical characteristics of granulated zeolites ZSM-5 in H-form with high degree of crystallinity with micro-meso-macroporous structure
https://doi.org/10.18412/1816-0387-2025-4-3-10
Abstract
The methods for preparing granulated ZSM-5 zeolites in the H-form with a high degree of crystallinity with a micro-meso-macroporous structure using synthetic amorphous aluminosilicates obtained by precipitation from aqueous solutions of sodium silicate and aluminum sulfate or by sol-gel synthesis using tetraethyl orthosilicate and aluminum nitrate are described. It is shown that the nature of the amorphous aluminosilicate affects the crystallization conditions of the granulated zeolite, as well as the morphology and dispersion of the resulting ZSM-5 zeolite crystals.
