Example Embodiment
[0028] Example 1
[0029] The preparation of hydrocracking catalyst L1 is as follows:
[0030] At room temperature, add 2.4 g of ammonium nitrate to 20 g of deionized water to make a solution. Then 15 g of mordenite was added. Stir evenly, in a water bath at 95°C for 12 hours. The slurry is filtered, the filter cake is dried at 130°C, and then roasted at 600°C for 4 hours in an air atmosphere containing 40% molar water vapor with a gas-agent volume ratio of 1200 to obtain modified zeolite, which is crushed and ground into fine powder spare. Commercially available SB aluminum hydroxide dry rubber powder 100g, mixed with 2g dichlorobenzene, and then poured into 100g hydrochloric acid aqueous solution, the mass concentration of the hydrochloric acid aqueous solution is 1.8%. Stir until it is gelatinous, filter, dry at 120°C, and calcinate in dry air at 500°C for 5 hours to obtain activated alumina powder. Mix the modified molecular sieve and activated alumina powder, add 3 g poly...

[0037] Example 2
[0038] The preparation of hydrocracking catalyst L2 is as follows:
[0039] At room temperature, add 3 g of ammonium nitrate to 20 g of deionized water to make a solution. Then 14 g of Hβ zeolite was added. Stir evenly, in a water bath at 90°C for 6 hours. The slurry is filtered, the filter cake is dried at 110°C, and then roasted at 600°C for 4 hours in an air atmosphere containing 30% molar water vapor with a gas-agent volume ratio of 600 to obtain modified zeolite, which is crushed and ground into fine powder spare. Commercially available SB aluminum hydroxide dry rubber powder 100g, mixed with 1.8g dichlorobenzene, and then poured into 100g hydrochloric acid aqueous solution, the mass concentration of the hydrochloric acid aqueous solution is 3%. Stir until it is gelatinous, filter, dry at 120°C, and calcinate in dry air at 500°C for 5 hours to obtain activated alumina powder. Mix the modified molecular sieve and activated alumina powder, add 4 g of sesa...
