Embodiment 1
[0094] Example 1 Sample 1 # preparation
[0095] Mix 0.59g of aluminum isopropoxide, 12g of tetrapropylammonium hydroxide, 13mL of ethyl orthosilicate, 1.6mL of hexadecyltrimethoxysilane and 50mL of ethanol in a beaker, and stir at 25°C until a gel is formed; The gel was dried at 25°C for 72h, and then transferred to a 250mL stainless steel hydrothermal kettle with a polytetrafluoroethylene liner. The polytetrafluoroethylene liner contained 50mL of water and crystallized at 170°C for 75h; filtered and washed After that, the multi-stage porous ZSM-5 molecular sieve sample was obtained, which was designated as sample 1 # .
Embodiment 2
[0096] Example 2 Sample 2 # preparation of
[0097] Mix 0.40g of aluminum isopropoxide, 12g of tetrapropylammonium hydroxide, 13mL of ethyl orthosilicate, 1.6mL of hexadecyltrimethoxysilane and 50mL of ethanol in a beaker, and stir at 25°C until a gel is formed; The gel was dried at 25°C for 72h, and then transferred to a 250mL stainless steel hydrothermal kettle with a polytetrafluoroethylene liner. The polytetrafluoroethylene liner contained 50mL of water and crystallized at 175°C for 70h; filtered and washed After that, the multi-stage porous ZSM-5 molecular sieve sample was obtained, which was designated as sample 2 # .
Embodiment 3
[0098] Example 3 Sample 3 # preparation of
[0099] Mix 0.238g of aluminum isopropoxide, 12g of tetrapropylammonium hydroxide, 13mL of ethyl orthosilicate, 1.6mL of hexadecyltrimethoxysilane and 50mL of ethanol in a beaker, and stir at 25°C until a gel is formed; The gel was dried at 25°C for 72h, and then transferred to a 250mL stainless steel hydrothermal kettle with a polytetrafluoroethylene liner. The polytetrafluoroethylene liner contained 50mL of water and crystallized at 175°C for 72h; filtered and washed After that, the multi-stage porous ZSM-5 molecular sieve sample was obtained, which was designated as sample 3 # .
