Examples
Embodiment 1
[0088] Weigh 18g of polyethylene glycol 2000 (that is, polyethylene glycol with a molecular weight of 2000, the same below), stir and dissolve in measured water to prepare wetting solution I. Use this wetting solution I to impregnate 300g of the S1 carrier, then perform 10h of curing, and after drying at 120°C for 3h, the prepared sample is designated as B1.
[0089] The above-mentioned B1 sample was spray-impregnated with an equal volume of impregnating solution containing Mo, Ni, and P (the first impregnating solution). After the spray-immersing, it was directly dried at 120°C for 3 hours and roasted at 480°C for 2 hours. The obtained sample was designated as Z1 .
[0090]Weigh 15g of tartaric acid, stir and dissolve in 45g of water to prepare a wetting solution. Spray and soak the wetting solution II evenly on Z1 for 15 minutes. After spraying and immersing in wetting solution II, dry at 100°C for 2 hours, impregnate the above-mentioned carrier with an equal volume of imp...
Embodiment 2
[0092] Weigh 24g of polyethylene glycol 1000, stir and dissolve in measured water to prepare wetting solution I. Use this wetting solution I to impregnate 300g of S2 carrier in an equal volume, then perform 5h of curing, and after drying at 120°C for 3h, the prepared sample is designated as B2.
[0093] Spray and impregnate the B2 sample with an equal volume of impregnating solution (first impregnating solution) containing Mo, Ni, and P. After spraying, divide the obtained sample into three parts on average. The first sample is directly dried at 120°C for 3 hours and roasted at 480°C for 2 hours. The obtained sample is marked as Z2; the second sample is cured for 1h, dried at 120°C for 3h, and roasted at 480°C for 2h, and the sample obtained is marked as Z3; the third sample is cured for 3h, dried at 120°C for 3h, and roasted at 480°C After 2h, the prepared sample was designated as Z4.
[0094] Weigh 1.0 g of malic acid, stir and dissolve in 6 g of ethanol to prepare wetting ...
Embodiment 3
[0096] Weigh 4g of polyethylene glycol 8000, stir and dissolve in the measured aqueous solution to prepare wetting solution I. Impregnate 200g of S3 carrier with equal volume of this wetting solution I, then perform 5h of curing, and after drying at 120°C for 3h, the prepared sample is designated as B3.
[0097] The B3 sample was spray-impregnated with an equal volume of impregnation solution containing Mo, Ni, and P (the first immersion solution), and dried directly at 120°C for 3 hours. The obtained sample was designated as Z5.
[0098] Weigh 7g each of citric acid and malonic acid, stir and dissolve in 40g water to prepare wetting solution II. Spray and soak the wetting solution II evenly on the Z5 for 25 minutes. The above sample was impregnated with an equal volume of impregnation solution containing Mo, Co, and P (the second impregnation solution). After the impregnation, it was cured for 1 hour and dried at 120°C for 3 hours. The obtained catalyst was designated as C7....
