Examples
Example Embodiment
[0027] Example 1
[0028] Mix the ZSM-5 molecular sieve with a silicon-to-aluminum molar ratio of 50 and pseudo-boehmite at a weight ratio of 3:1. Add 19.2 g of 85% orthophosphoric acid and 30 mL of distilled water, and stir evenly; add 6.4 g of triethylamine and stir. Evenly. Kneading and extruding into a strip. Put it into the crystallization kettle. Crystallize hydrothermally at 125°C for 6 hours. Then, it was hydrothermally crystallized at 160°C for 24 hours. Take it out and fire it at 580°C. Sampling and characterization after crushing. XRD characterization results show (see figure 1 ), in addition to the ZSM-5 crystal form, there is also AlPO 4 -5 crystal form appears; SEM characterization results show that there are small particles attached to the surface of bulk ZSM-5 (see figure 2 ).

[0030] Mix the ZSM-5 molecular sieve with a silicon-to-aluminum molar ratio of 50 and pseudo-boehmite at a weight ratio of 4:1; add 3.6 g of triethylamine and 30 mL of distilled water, and stir evenly; add 9.65 g of 85% orthophosphoric acid and stir Evenly. Kneading and extruding into a strip. Put it into the crystallization kettle. Crystallize hydrothermally at 150°C for 4 hours. Then, it was hydrothermally crystallized at 200°C for 10 hours. Take it out and roast it at 580°C to obtain a strip-shaped molecular sieve.

[0031] Example 3
[0032] Mix ZSM-5 molecular sieve with a silicon-aluminum molar ratio of 50 and pseudo-boehmite at a weight ratio of 5:1. Add 19.6 g of 85% orthophosphoric acid and stir well; add 8.1 g of triethylamine and 10 mL of distilled water, and stir. Evenly. Kneading and extruding into a strip. Put it into the crystallization kettle. Crystallize hydrothermally at 100°C for 24 hours. Then, it was hydrothermally crystallized at 150°C for 48 hours. Take it out and roast it at 580°C to obtain a strip-shaped molecular sieve.
