Examples
Embodiment 1
[0086] Weigh 15g of tartaric acid, stir and dissolve in 45g of water to prepare wetting solution I. Take 300g of the S1 carrier, and spray the wetting solution I evenly on the S1 carrier for 15 minutes. After spraying and immersing in wetting solution I, dry at 100°C for 2 hours, impregnate the above carrier with an equal volume of impregnating solution containing Mo, Co, and P (first impregnating solution), and divide the obtained samples into three parts evenly after impregnating. One sample was not cured, dried at 120°C for 3 hours, roasted at 480°C for 2 hours, and the obtained sample was marked as B1; the second sample was cured for 1 hour, dried at 120°C for 3 hours, and roasted at 480°C for 2 hours, and the obtained sample was marked as B2; The third sample was cured for 3 hours, dried at 120°C for 3 hours, and roasted at 480°C for 2 hours. The prepared sample was designated as B3.
[0087] Weigh 6g of polyethylene glycol 2000 (that is, polyethylene glycol with a molec...
Embodiment 2
[0090] Weigh 3 g of malic acid, stir and dissolve in 24 g of ethanol to prepare wetting solution I. Take 300g of the S2 carrier, and spray the wetting solution I evenly on the S2 carrier for 5 minutes. The above-mentioned carrier was impregnated with an equal volume of impregnation solution (first impregnation solution) containing Mo, Co, and P. After impregnation, it was cured for 1 hour, dried at 120°C for 3 hours, and calcined at 480°C for 2 hours. The obtained sample was designated as B4.
[0091] Weigh 24 g of polyethylene glycol 1000, stir and dissolve in measured water to prepare solution II. The sample B4 was impregnated with an equal volume of this solution II, and then cured for 5 hours. After drying at 120°C for 3 hours, the prepared sample was designated as Z4.
[0092]The Z4 sample was spray-impregnated with an equal volume of impregnating solution containing Mo, Ni, and P (the second impregnating solution). After spraying, the sample was divided into three parts...
Embodiment 3
[0094] Weigh 7g each of citric acid and malonic acid, stir and dissolve in 40g water to prepare wetting solution I. Take 200g of the S3 carrier, and spray the wetting solution I evenly on the S3 carrier for 25 minutes. The above-mentioned carrier was impregnated with an equal volume of Mo, Co, and P impregnating solution (the first impregnating solution). After impregnation, it was cured for 1 hour, dried at 120°C for 3 hours, and calcined at 480°C for 2 hours. The obtained sample was designated as B5.
[0095] Weigh 4g of polyethylene glycol 8000, stir and dissolve in the measured aqueous solution to prepare solution II. The sample B5 was impregnated with equal volume of this solution II, and then cured for 5 hours. After drying at 120°C for 3 hours, the prepared sample was designated as Z5.
[0096] The Z5 sample was spray-impregnated with an equal volume of impregnating solution containing Mo, Ni, and P (the second impregnating solution), and dried directly at 120°C for 3 ...
