Embodiment 1
[0023] 4.26g NaAlO 2 Mix evenly with 19.08g of sodium hydroxide solution in a 500ml stainless steel reaction kettle, add 53g of silica gel, 408.2g of deionized water, and 18.96g of HMI into the kettle in sequence under stirring, and then add 1.65g of CH 3 1, finally add 55g ZSM-22 again. After continuing to stir for 10 minutes, the reaction vessel was sealed and crystallized at 120° C. for 15 hours. After the crystallization was completed, a solid product (MCM-22 / ZSM-22) was isolated, numbered S-1, and the weight content of MCM-22 was 25.4%.
Embodiment 2
[0025] 1.488g NaAlO 2 Mix evenly with 36.06g sodium hydroxide solution in a 500ml stainless steel reaction kettle, mix 33g silica gel, 3.3gCHCl under stirring 3、 Add 359.3g deionized water and 3.00g HMI to the kettle in turn, and finally add 100g ZSM-22. After continuing to stir for 10 minutes, the reaction vessel was sealed and crystallized at 130° C. for 20 h. After the crystallization was completed, a solid product (MCM-22 / ZSM-22) was isolated, numbered S-2, and the weight content of MCM-22 was 11.1%.
Embodiment 3
[0027] 1.136g NaAlO 2 Mix evenly with 24.04g of sodium hydroxide solution in a 500ml stainless steel reaction kettle, add 22g of silica gel, 237g of deionized water, 12g of HMI and 6g of cyclohexane into the kettle in sequence while stirring, and finally add 120g of ZSM-22. After continuing to stir for 10 minutes, the reaction vessel was sealed and crystallized at 120° C. for 15 hours. After the crystallization was completed, a solid product (MCM-22 / ZSM-22) was isolated, numbered S-3, and the weight content of MCM-22 was 7.5%.
