Embodiment 1
[0060]This embodiment provides a method for preparing ZSM-5 nano flake agglomerates, the preparation method includes:
[0061]The silica sol, tetrapropylammonium bromide, ethylamine and deionized water were mixed according to a molar ratio of 1:0.2:1.2:18. The mixing was stirring and mixing in a water bath at 30°C for 30 minutes, and the resulting mixed solution was heated at 100 Crystallize at ℃ for 36 hours to obtain nano crystallite emulsion;
[0062]The sodium hydroxide and aluminum sulfate octahydrate are mixed and dissolved in water, and silica sol is added dropwise to obtain a silica-aluminum hybrid gel. The silica-aluminum hybrid gel is stirred in a 30°C water bath for 30 minutes, and the silica sol, The molar ratio of inorganic base, aluminum source and water is 1:0.01:0.08:10;
[0063]The nano-microcrystalline emulsion was added dropwise to the silica-aluminum hybrid gel and stirred for 30 minutes. The addition amount of the nano-microcrystalline emulsion was 0.7 of the mass of sil...
