Abstract

The invention provides a Y / EU-1 / SBA-15 / ASA / MOF composite material and a preparation method thereof. The method comprises the following steps: synthesizing a guiding agent, and synthesizing a small grain size Y-type molecular sieve by adopting a hydrothermal crystallization method; adding surfactant, EU-1 and SBA-15 molecular sieve slurry and alkaline aluminum-source solution into the slurry containing molecular sieve, and washing, drying and roasting the product to obtain Y / EU-1 / SBA-15 / ASA complex; uniformly mixing and stirring with a metal salt aqueous solution, and drying to obtain a metal-loaded Y / EU-1 / SBA-15 / ASA composite material; adding carboxyl-containing organic acid into an organic solvent of alcohol and amide, and uniformly mixing to obtain organic mixture; and adding the metal-loaded Y / EU-1 / SBA-15 / ASA material into the organic mixture, uniformly stirring, and reacting to obtain the Y / EU-1 / SBA-15 / ASA / MOF composite material.

Description

technical field [0001] The invention provides a Y / EU-1 / SBA-15 / ASA / MOF composite material and a preparation method thereof, specifically, a Y molecular sieve, EU-1 molecular sieve, SBA-15 molecular sieve and amorphous silicon aluminum (ASA) Composite material formed by in-situ coating, MOF (metal-organic framework) metal organic framework porous material is synthesized on the surface of the above composite material to form Y / EU-1 / SBA-15 / ASA / MOF composite material . Background technique [0002] Molecular sieve complex refers to a composite material that combines molecular sieves and other substances through the interaction between molecules, atoms or ions. Regular materials with mesoporous structures such as MCM-41 mesoporous molecular sieves are suitable for the transformation of organic macromolecules due to their large pore structure, but their poor thermal stability, hydrothermal stability and weak acidity limit their Applications of this type of material in the field o...
