Embodiment 1
[0033] Fully dissolve 0.4g NaOH with 60g of deionized water, then add 1g of template agent HMBr, stir for 10min, add 0.75g of sodium metaaluminate, stir until the solution is clear, then add 25g of silica sol (silica mass fraction 40%) and 0.25g of EU -1 molecular sieve seed crystal and stirred for 30 min. In a water bath at 70°C, evaporate the water in the mixture to reduce the weight of the mixture by 45g, then add 2g of template agent HMBr, stir for 10 minutes, put it into a crystallization kettle, crystallize at 170°C for 70h, and cool to room temperature after crystallization , after suction filtration, drying and roasting, the EU-1 zeolite molecular sieve was obtained. The specific ratio and relative crystallinity are shown in Table 1.
Embodiment 2
[0035] Fully dissolve 0.4g NaOH with 60g of deionized water, then add 0.6g of template agent HMBr, stir for 10min, add 0.75g of sodium metaaluminate, stir until the solution is clear, then add 25g of silica sol (silica mass fraction 40%) and 0.25 The gEU-1 molecular sieve seed crystals were stirred for 30 min. In a water bath at 70°C, evaporate the water in the mixture to reduce the mass of the mixture by 50g, then add 1.8g template agent HMBr, stir for 10 minutes, then put it into the crystallization kettle, crystallize at 170°C for 70h, and cool to At room temperature, the EU-1 zeolite molecular sieve was prepared after suction filtration, drying and roasting. The specific ratio and relative crystallinity are shown in Table 1.
Embodiment 3
[0037]Fully dissolve 0.4g NaOH with 60g of deionized water, then add 0.3g of template agent HMBr, stir for 10min, add 0.75g of sodium metaaluminate, stir until the solution is clear, then add 25g of silica sol (silica mass fraction 40%) and 0.25 The gEU-1 molecular sieve seed crystals were stirred for 30 min. In a water bath at 70°C, evaporate the water in the mixture to reduce the mass of the mixture by 55g, then add 0.9g template agent HMBr, stir for 10 minutes, then put it into the crystallization kettle, crystallize at 170°C for 70h, and cool to At room temperature, the EU-1 zeolite molecular sieve was prepared after suction filtration, drying and roasting. The specific ratio and relative crystallinity are shown in Table 1.
