SYNTHETIC POROUS CRYSTALLINE MATERIAL AND A METHOD FOR PREPARATION THEREOF Russian patent published in 2007 - IPC C01B39/48

Abstract RU 2312063 C1

FIELD: zeolite-based sorbents and catalysts.

SUBSTANCE: synthetic porous crystalline material is prepared via hydrothermal crystallization of reaction mixture containing silicon source, aluminum source, alkali metal source, water, zeolite "seed", and organic structure-forming compound (ε-caprolactam) has following composition expressed in molar proportions: SiO₂/Al₂O₃ =20-90, R/SiO₂=0.03-1.0, Na⁺/SiO₂=0.1-1.0, OH^-/SiO₂=0.1-1.0, H₂O/SiO₂=10-100. Material is characterized by MFI zeolite structure and can be used for preparation of high-efficiency catalysts for various hydrocarbon conversion reactions.

EFFECT: optimized composition of material.
