[0034] Preparation of Z1: β molecular sieve B1, macroporous alumina (pore volume 1.0mL / g, specific surface area 400m 2 / g), binder (the molar ratio of nitric acid to small-pore alumina is 0.3) were put into a roller compactor and mixed, added water, rolled into a paste, extruded, and dried at 110°C for 4 hours. Then calcined at 550° C. for 4 hours to obtain carrier Z1.
[0035] Preparation of Z2: β molecular sieve B1, Y-type molecular sieve Y1, macroporous alumina (pore volume 1.0mL / g, specific surface area 400m 2 / g), binder (the molar ratio of nitric acid to small-pore alumina is 0.3) were put into a roller compactor and mixed, added water, rolled into a paste, extruded, and dried at 110°C for 4 hours. Then calcined at 550° C. for 4 hours to obtain carrier Z2.
[0036] Preparation of Z3: β molecular sieve B2, Y type molecular sieve Y2, macroporous alumina (pore volume 1.0mL / g, specific surface area 400m 2 / g), binder (the molar ratio of nitric acid to small-pore alumina i...
Embodiment 1
[0041] Weigh 8.1 g of ammonium tetraborate, add an appropriate amount of deionized water to dissolve, and make the volume 105 mL to prepare solution A1. Weigh 21.0 g of water-soluble silicone oil A, add an appropriate amount of deionized water to dissolve, and make the volume 105 mL to prepare solution B1. While stirring, slowly pour 35mL of B1 solution into 35mL of A1 solution, and add an appropriate amount of deionized water to make the final volume 72mL to prepare C1 solution.
[0042] Take 100g of hydrogenation-modifying catalyst support Z1, spray the solution C1 evenly on the hydrogenation-modification catalyst support Z1, and after curing for 10 hours, heat-treat at 100°C for 2h and 220°C for 2h to obtain the modified support S1.
[0043] Take 100g of hydrogenation modification catalyst carrier Z1, dilute 35mL of solution B1 to 72mL with deionized water, spray evenly on the carrier Z1, keep in good condition for 10 hours, heat-treat at 100°C for 2 hours, then dilute 35mL...
Embodiment 2
[0045] Weigh 3.6g of boric acid and 32.0g of water-soluble silicone oil B, add appropriate amount of deionized water to dissolve, make the volume 146mL, and prepare solution C2.
[0046] Take 100g of hydrogenation-modifying catalyst support Z1, and evenly spray 73mL of solution C2 on the hydrogenation-modification catalyst support Z1.
