Embodiment 1
[0034] Preparation of hydrogenation catalyst component D1 with desulfurization activity:
[0035] Take 1000 grams of macroporous aluminum hydroxide, add nitric acid and water to obtain HNO 3 Content is 2.2%, water content is the pasty mixture of 65%, extrude above-mentioned mixture on extruder, obtain the clover-shaped bar of diameter 1.5 millimeters, 100 ℃ of drying 2 hours, then obtain carrier at 600 ℃ of roasting 5 hours, take Ammonium heptamolybdate and nickel nitrate were prepared into an aqueous solution, and the above carrier was impregnated with equal volume for 30 minutes to obtain a wet strip with a molybdenum oxide content of 24% and a nickel oxide content of 4% (calculated on a dry basis after roasting), and dried at 100°C for 2 hours. Then calcined at 550° C. for 2 hours to obtain catalyst D1.
[0036] It was determined that the average pore diameter of the catalyst D1 was 9.5 nanometers, and the specific surface area was 268.9 square meters per gram.
Embodiment 2
[0038] Preparation of hydrogenation catalyst component D2 with desulfurization activity:
[0039] Take 1000 grams of macroporous amorphous silica-alumina, add nitric acid and water to obtain HNO 3 Content is 2.3%, and water content is 68% pasty mixture, extrude above-mentioned mixture on extruder, obtain the cylindrical bar of diameter 1.5 millimeters, dry 18 hours at 80 ℃, then obtain carrier at 500 ℃ roasting 9 hours, take Ammonium heptamolybdate and nickel nitrate were prepared into an aqueous solution, and the above carrier was impregnated with equal volume for 30 minutes to obtain a wet strip with a molybdenum oxide content of 27% and a nickel oxide content of 5% (calculated on a dry basis after roasting), and dried at 100°C for 2 hours. Then calcined at 500° C. for 9 hours to obtain catalyst D2.
[0040] It was determined that the average pore diameter of the catalyst D2 was 9.8 nanometers, and the specific surface area was 253.3 square meters per gram.
Embodiment 3
[0042] Preparation of hydrogenation catalyst component D3 with desulfurization activity:
[0043] Take 1000 grams of aluminum hydroxide containing 0.9% fluorine, add nitric acid and water to obtain HNO 3 Content is 1.3%, water content is 60% pasty mixture, extrude above-mentioned mixture on extruder, obtain the cylindrical bar of diameter 1.5mm, dry 6 hours at 140 ℃, then obtain carrier at 550 ℃ roasting 2 hours, take Ammonium heptamolybdate and cobalt nitrate were prepared into an aqueous solution, and the above carrier was impregnated with equal volume for 30 minutes to obtain a wet strip with a molybdenum oxide content of 16% and a cobalt oxide content of 3% (calculated on a dry basis after roasting), and dried at 100°C for 2 hours. Then calcined at 580° C. for 3 hours to obtain catalyst D3.
[0044] It was determined that the average pore diameter of the catalyst D3 was 10.7 nanometers, and the specific surface area was 277.5 square meters per gram.
