Title:
METAL-MODIFIED ZSM-5 MOLECULAR SIEVE CATALYST, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/066066
Kind Code:
A1
Abstract:
Provided in the present application are a metal-modified ZSM-5 molecular sieve catalyst, and a preparation method therefor and the use thereof. The preparation method comprises the following steps: mixing a ZSM-5 molecular sieve, ethyl orthosilicate, trichloroacetic acid and water for a reaction, followed by filtration, so as to obtain an intermediate; and mixing the intermediate, a melamine solution and a metal salt solution, followed by drying and roasting, so as to obtain the metal-modified ZSM-5 molecular sieve catalyst. The prepared catalyst has the advantages of good catalytic activity, selectivity, stability, etc., and the preparation process is simple, and is easy to operate.
