[0044] Embodiment 1: the preparation of ZSM-5 zeolite molecular sieve
[0045] (1) Coarse-porous silica gel preparation and aging:
[0046] Add 3 grams of tetrapropylammonium bromide (0.011278195 mol equivalent to 0.09022556 times that of coarse-pore silica gel) into 5 grams of deionized water (0.277777778 mol equivalent to 2.222222222 times that of coarse-pore silica gel), stir and disperse to obtain a template solution ;
[0047] Add 5 grams of deionized water (0.277777778mol is equivalent to 2.222222222 times that of coarse-pore silica gel) into 7.5 grams of coarse-pore silica gel (0.125mol), stir, and then add template agent solution dropwise to the silicon source solution, after stirring for 4 hours, then Aged at 50°C for 6 hours. Take 0.5 g of sodium hydroxide (0.0125 mol is equivalent to 0.1 times of coarse-pore silica gel) and add it to 5 g of deionized water (0.277777778 mol is equivalent to 2.222222222 times of coarse-pore silica gel), then add the above solution d...
