Embodiment 1
[0039] Take 140g (calculated on a dry basis, the same below) HY molecular sieve with a grain size of 100 nanometers and 60g of alumina and 6.7g of scallop powder, mix evenly, and knead with dilute nitric acid with a mass percentage concentration of 4% as a solvent to knead and extrude. After natural drying at 120°C for 12 hours, the temperature was programmed to rise to 550°C for 4 hours to obtain a semi-finished catalyst. Then weigh 12.14g of lead nitrate to prepare a mixed aqueous solution, impregnate the obtained semi-finished catalyst with equal volume at room temperature for 24 hours, dry at 120°C for 12 hours, and then heat up to 550°C for 4 hours to obtain catalyst B.
Embodiment 2
[0041] Take 140g of HY molecular sieve with a grain size of 80nm, mix it with 60 alumina and 4.5g of turnip powder evenly, knead and extrude it with dilute nitric acid with a concentration of 4% by mass as a solvent, and dry it at 120°C after natural drying After 12 hours, the temperature was programmed to rise to 550° C. and calcined for 4 hours to obtain a semi-finished catalyst. Then weigh 9.21g of ammonium metamolybdate to prepare a mixed aqueous solution, impregnate it with the obtained semi-finished catalyst at room temperature for 24 hours, dry at 120°C for 12 hours, and then heat up to 550°C for 4 hours to obtain catalyst C.
Embodiment 3
[0043] Take 140g of HY molecular sieve with a grain size of 50 nanometers, mix with 60g of alumina and 3.3g of turnip powder, knead and extrude it with dilute nitric acid with a mass percentage concentration of 4% as a solvent, and dry it naturally at 120°C for 12 hours Afterwards, the temperature was programmed to rise to 550° C. for 4 hours to obtain a semi-finished catalyst. Then weighed 10.37g of nickel nitrate to prepare a mixed aqueous solution, impregnated it with the obtained semi-finished catalyst at room temperature for 24 hours, dried at 120°C for 12 hours, and then programmed the temperature to 550°C for 4 hours to obtain catalyst D.
