The invention relates to a preparation method of a mesoporous Fe-Beta molecular sieve, and belongs to the technical field of molecular sieve preparation. The preparation method of the mesoporous Fe-Beta molecular sieve of the present invention uses the slag in the slurry when preparing the iron-based molecular sieve as the silicon source, aluminum source and iron source, adds alkali source and template agent to prepare gel, and then crystallizes Obtain Fe-Beta molecular sieve. The preparation method of the mesoporous Fe-Beta molecular sieve of the present invention makes full use of the waste slurry during the preparation of the iron-based molecular sieve, which significantly reduces the cost of raw materials, the process is simple, the discharge of pollutants is reduced, and the prepared product has excellent performance in application. |
