Title:
EFFICIENT, FAST AND ENVIRONMENTALLY-FRIENDLY PREPARATION METHOD FOR ZEOLITE MOLECULAR SIEVE
Document Type and Number:
WIPO Patent Application WO/2020/238233
Kind Code:
A1
Abstract:
Provided is a method for preparing a zeolite molecular sieve, comprising the following steps: uniformly mixing at least one among a silicon source, an aluminum source and a phosphorus source, an alkaline substance, a template agent, and water to obtain a zeolite molecular sieve precursor solution, wherein the precursor solution at least comprises the silicon source; aging the precursor solution at 20-30°C for 10-15 h; subjecting the aged solution to ionizing radiation, and then washing an obtained solid until neutral and then drying to obtain the zeolite molecular sieve. The described method has the advantages of being environmentally friendly, simple and extremely low-cost; under the irradiation of an ionizing radiation source, the synthesis period of the zeolite molecular sieve is short, heating is not required during the preparation process, energy consumption is reduced, and a high-pressure system is avoided.
