Embodiment 1
[0022] (1) Preparation of catalyst DeLaZSM-5: Add 10 parts of 0.8M Na in 10 parts of HZSM-5 zeolite molecular sieve 2 CO 3 Solution, reacted at 80°C for 4 hours; after the reaction, let it stand and pour off the supernatant, and then add 10 parts of 0.8M Na 2 CO 3 Solution, react at 80°C for 4 hours, filter, wash with 100 parts of deionized water, and dry at 120°C for 12 hours; then add 10 parts of deionized water to the dried solid, react at 80°C for 2 hours, filter, Wash with 100 parts of deionized water, dry at 120°C for 12 hours, and activate at 360°C for 24 hours to obtain DeZSM-5. The prepared DeZSM-5 was treated with 10 parts of 0.8M LaCl 3 Ion exchange was performed at 100°C for 30 minutes with 2450 MHz microwave irradiation. Wash with boiling water to the washing liquid La 3+ The detection was zero, then dried at 120°C for 12 hours, and then activated at 600°C for 5 hours to obtain DeLaZSM-5.

Embodiment 2
[0025] (1) Preparation of catalyst DeLaZSM-5: Add 500 parts of 2M Na in 10 parts of NaZSM-5 zeolite molecular sieve 2 CO 3 solution, and reacted at 120°C for 2 hours. After the reaction, let it stand and pour off the supernatant, then add 500 parts of 2M Na 2 CO 3Solution, react at 120°C for 2 hours, filter, wash with 1500 parts of deionized water, and dry at 120°C for 12 hours; then add 500 parts of deionized water to the dried solid, react at 120°C for 2 hours, filter, Wash with 1500 parts of deionized water, dry at 120°C for 12 hours, and activate at 450°C for 10 hours to obtain DeZSM-5; prepare DeZSM-5 with 50 parts of 2M LaCl 3 Use 2450MHz microwave radiation to carry out ion exchange at 80°C for 5 minutes. After exchange, wash with boiling water until La 3+ The detection was zero, then dried at 120°C for 12 hours, and then activated at 300°C for 24 hours to obtain DeLaZSM-5.
