Examples
Embodiment 1
[0021] The ZSM-5 prepared by Comparative Example 1 was roasted at 500°C for 7 hours, and then exchanged with 1 mol / liter of hydrochloric acid solution. The exchange temperature was 90°C and the time was 5 hours. The sodium solution is subjected to alkali treatment, the treatment time is 16 hours, and the solid-to-liquid ratio is 1 / 10 (g / g). After washing and drying, it is exchanged twice with 1 mol / L hydrochloric acid solution at 90°C for two hours each time. Sample B was obtained by washing, drying and calcining at 550° C. for 5 hours. Under the same reaction conditions as in Example 1, its product distribution is shown in Table 1.
Embodiment 2
[0023]The ZSM-5 prepared by Comparative Example 1 was roasted at 450°C for 5 hours, and then exchanged with a 6 mol / liter hydrochloric acid solution. The exchange temperature was 90°C and the time was 5 hours. The sodium solution is subjected to alkali treatment, the treatment time is 8 hours, and the solid-to-liquid ratio is 1 / 20 (g / g). After washing and drying, it is exchanged twice with 1 mol / L hydrochloric acid solution at 90°C for two hours each time. Sample C was obtained by washing, drying and calcining at 500° C. for 6 hours. Under the same reaction conditions as in Example 1, its product distribution is shown in Table 1.
Embodiment 4
[0025] The ZSM-5 prepared by Comparative Example 1 was roasted at 300°C for 24 hours, and then exchanged with a 2 mol / liter phosphoric acid solution. The exchange temperature was 30°C and the time was 9 hours. The sodium solution is subjected to alkali treatment, the treatment time is 24 hours, and the solid-to-liquid ratio is 1 / 10 (g / g). After washing and drying, it is exchanged twice with 3 mol / L phosphoric acid solution at 90° C. for two hours each time. Sample D was obtained by washing, drying and calcining at 350° C. for 16 hours. Under the same reaction conditions as in Example 1, its product distribution is shown in Table 1.
