Embodiment 1
[0036] ZSM-5, Y molecular sieve and SAPO-11 molecular sieve with the silicon-aluminum ratio of group A being 120 are ZSM-5 by mass percentage: Y molecular sieve: SAPO-11 molecular sieve is 70%: 22%: 8% ratio mixing, then Treat in 0.08mol / L hydrochloric acid at 50°C for 1 hour, wash with deionized water until the pH is 7, and dry at 120°C. Finally, equal volumes of Ag, Sm, Ce, and Zn solutions were impregnated, and the loads were 0.05% for Ag, 1% for Sm, 0.5% for Ce, and 1% for Zn, and then dried at 120°C for 3 hours and roasted at 400°C. 4h.
[0037] The 13X molecular sieves of group B were treated with water vapor at 550°C for 4 hours, then treated with water vapor at 550°C, and finally impregnated with an equal volume of Lu solution, dried at 120°C for 3 hours, and calcined at 400°C for 4 hours. The Lu content accounted for 1.5% of group B.
[0038] The medium-volume impregnation of the molecular sieves of the two groups A and B was completed under ultrasonic, the impregnat...
Embodiment 2
[0043]ZSM-5, Y molecular sieve, and SAPO-11 molecular sieve with a silicon-aluminum ratio of group A of 209 are ZSM-5 in mass percentage: Y molecular sieve: SAPO-11 molecular sieve is 60%: 30%: 10% The ratio is mixed, and then Treat in 0.05mol / L hydrochloric acid at 60°C for 1 hour, wash with deionized water until the pH is 7, and dry at 120°C. Finally, equal volumes of Ag, Sm, Ce, and Zn solutions were impregnated, and the loads were 0.1% for Ag, 2% for Sm, 0.3% for Ce, and 3% for Zn, and then dried at 120°C for 3 hours and roasted at 400°C. 4h.
[0044] The 13X molecular sieves of group B were treated with water vapor at 550°C for 4 hours, then treated with water vapor at 550°C, and finally impregnated with an equal volume of Lu solution, dried at 120°C for 3 hours, and calcined at 400°C for 4 hours. The Lu content accounted for 2% of group B.

Embodiment 3
[0050] ZSM-5, Y molecular sieve, and SAPO-11 molecular sieve with the silicon-aluminum ratio of group A being 500 are ZSM-5 by mass percentage: Y molecular sieve: SAPO-11 molecular sieve is 80%: 14%: 6% ratio mixing, then Treat in 0.2mol / L hydrochloric acid at 70°C for 1 hour, wash with deionized water until the pH is 7, and dry at 120°C. Finally, equal volumes of Ag, Sm, Ce, and Zn solutions were impregnated, and the loads were 0.06% for Ag, 4% for Sm, 2% for Ce, and 5% for Zn, and then dried at 120°C for 3 hours and roasted at 400°C. 4h.
[0051] The 13X molecular sieves of group B were treated with water vapor at 550°C for 4 hours, then treated with water vapor at 550°C, and finally impregnated with an equal volume of Lu solution, dried at 120°C for 3 hours, and calcined at 400°C for 4 hours. The Lu content accounted for 2.5% of group B.
[0052] The medium-volume impregnation of the molecular sieves of the two groups A and B was completed under ultrasonic, the impregnatin...
