Embodiment 1
[0030] The preparation method of the carbon-containing molecular sieve catalyst of the present embodiment, such as figure 1 shown, including the following steps:
[0031] 1) Roast the original powder of mordenite molecular sieve, then immerse it in 1mol / L ammonium nitrate solution for 2 hours for ammonia exchange, then wash and dry, repeat the steps of ammonia exchange, washing and drying 3 times, and then roast at 550°C for 4 hours, Prepared hydrogen-type mordenite molecular sieve;
[0032] 2) Take 0.05mol La(NO 3 ) 3 and 0.05mol Co(NO 3 ) 2 Add an appropriate amount of water, after the dissolution is complete, add ammonia water (in the form of NH 3 1 mol), stir evenly, and set the volume to 100mL to obtain a complex solution;
[0033] Take 2.0 g of the hydrogen-type mordenite molecular sieve prepared in step 1) and immerse it in 100 mL of the complex solution, stir at 50 °C for 24 h to perform complex ion exchange, then filter, dry, and then roast at 500 °C for 4 h to ...
