Recyclable polymer template agent, hierarchical gradient pore beta zeolite and preparation methods thereof

Abstract

The present invention relates to the field of zeolite technology, and more particularly to a recyclable polymer template agent, a hierarchical gradient pore Beta zeolite, and a green preparation method thereof. By synthesizing a polymer template agent and utilizing the unique temperature sensitivity conferred by the combination of the hydrophilic quaternary amide group and the hydrophobic isopropyl group in the polyquaternary ammonium salt structure of the recyclable polymer template agent provided by the present invention, the zeolite precursor is locked inside the gel at the zeolite synthesis temperature, directing the formation of the zeolite crystal structure; after crystallization is complete, the reaction temperature is lowered to room temperature, the polymer shell opens, and the locked zeolite crystals inside are released via a diffusion mechanism, followed by centrifugation to separate the polymer from the zeolite for removal.
