Embodiment 1
[0037] Dissolve 0.9g of sodium hydroxide in 22g of deionized water, add 0.51g of sodium metaaluminate after it is fully dissolved, and stir to fully dissolve to obtain solution A. Dissolve 15g of silica sol in 10g of deionized water, then add 3g of amantadine hydrochloride and 2.1g of phosphorylcholine, stir well to obtain solution B, dissolve 0.76g of copper sulfate pentahydrate in 5g of deionized water, then add 0.58g of tetrahydrochloride Ethylene pentamine, fully stirred for 2h, to obtain solution C. Under stirring, solutions A and B were slowly added to solution C, stirred for 4h and then allowed to stand for 24h. Then it was loaded into a kettle and crystallized at 120°C for 240h. The obtained product was washed with deionized water, suction filtered, dried at 110° C. for 12 hours, and the obtained powder was calcined at 550° C. for 6 hours to obtain a Cu-SSZ-13 molecular sieve catalyst. figure 1 It is the XRD figure of the nanometer Cu-SSZ-13 molecular sieve sample pr...

[0039] Dissolve 0.9 g of sodium hydroxide in 22 g of deionized water, add 2.8 g of pseudo-boehmite after it is fully dissolved, and stir thoroughly to obtain solution A. Dissolve 15g of silica sol in 10g of deionized water, then add 3g of amantadine hydrochloride and 2.1g of phosphorylcholine, stir well to obtain solution B, dissolve 0.76g of copper sulfate pentahydrate in 5g of deionized water, and then add 0.81g of ethyl Tetrasodium diaminetetraacetic acid was stirred thoroughly for 2 hours to obtain solution C. Under stirring, solutions A and B were slowly added to solution C, stirred for 4h and then allowed to stand for 24h. Then it was loaded into a kettle and crystallized at 200°C for 48h. The obtained product was washed with deionized water, suction filtered, dried at 110° C. for 12 hours, and the obtained powder was calcined at 550° C. for 6 hours to obtain a Cu-SSZ-13 molecular sieve catalyst. figure 2 It is the XRD figure of the nano Cu-SSZ-13 molecular sieve samp...

[0041] Dissolve 0.9 g of sodium hydroxide in 22 g of deionized water, add 2.8 g of pseudo-boehmite after it is fully dissolved, and stir thoroughly to obtain solution A. Dissolve 15g of silica sol in 10g of deionized water, then add 3g of amantadine hydrochloride and 2.1g of phosphorylcholine, stir well to obtain solution B, dissolve 0.76g of copper sulfate pentahydrate in 5g of deionized water, then add 0.58g of tetrahydrochloride Ethylene pentamine, fully stirred for 2h, to obtain solution C. Under stirring, solutions A and B were slowly added to solution C, stirred for 4h and then allowed to stand for 24h. Then put it in a kettle and place it at 160°C for 96h of crystallization. The obtained product was washed with deionized water, suction filtered, dried at 110° C. for 12 hours, and the obtained powder was calcined at 650° C. for 4 hours to obtain a Cu-SSZ-13 molecular sieve catalyst. image 3 It is the XRD figure of the nanometer Cu-SSZ-13 molecular sieve sample prepare...
