| Zusammenfassung: | The invention discloses a preparation method of an ordered mesopore ZSM-5 molecular sieve. The preparation method comprises the following steps of: firstly preparing an ordered mesopore silicon oxide molecular sieve serving as a silicon source through an organic template method; and then transforming the ordered mesopore silicon oxide molecular sieve into the ordered mesopore ZSM-5 molecular sieve in situ by adopting a hydrothermal method. The ordered mesopore ZSM-5 molecular sieve disclosed by the invention is provided with ordered micropores with pore diameter being 0.2-2 nanometers and ordered mesopores with pore diameter being 2-50 nanometers and has wide application prospect in the fields of petrochemical industry, petroleum processing, coal chemical industry, and the like. |
