Embodiment 1
[0049] HZSM-5 molecular sieves are usually synthesized in a conventional homogeneous reactor, and the synthesis conditions are:
[0050] First mix 12.50g Tetraethyl Tetrasilicate (silicon source), 12.00g Tetrapropylammonium Hydroxide (template), and 70g water (by adjusting the addition ratio of silicon source and water, the particle size of the synthetic molecular sieve can be changed) , stirred at 80°C, condensed and refluxed for 24h, then added 0.24g NaOH and 0.46g Al(NO 3 ) 3 9H 2 O (aluminum source), transferred to a polytetrafluoroethylene-lined stainless steel autoclave for static hydrothermal synthesis at 170°C for 24 hours, after quenching, centrifuged to wash the supernatant to pH ≈ 7, and then transferred to blast drying Oven dried at 110°C for 12 hours, then transferred to a muffle furnace and roasted at 550°C for 6 hours to remove the template agent, and after cooling, the sample was taken out to obtain NaZSM-5 zeolite, which was then treated with 1mol / L NH 4 NO...
