Embodiment 1
[0090] 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 the wetting solution Ⅰ, dry at 100°C for 2 hours, impregnate the above-mentioned carrier with an equal volume of impregnating solution containing Mo, Co, and P, and divide the obtained samples into three parts on average. 3h, 480°C for 2h, the sample obtained is marked as B1; the second sample was cured for 1h, dried at 120°C for 3h, and after 480°C for 2h, the sample obtained was marked as B2; the third sample was cured for 3h, after After drying at 120°C for 3 hours and calcining at 480°C for 2 hours, the prepared sample is designated as B3.
[0091] Weigh 6g 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 solution II. Samples B1, B2, an...
Embodiment 2
[0094] Weigh 24g of polyethylene glycol 1000, stir and dissolve in measured water to prepare wetting solution II. Use this wetting solution II to impregnate 300g of S2 carrier with an equal volume, then perform 5h of curing, and after drying at 120°C for 3h, the prepared sample is designated as B4. Spray and impregnate the above B4 sample with an equal volume of impregnation solution containing W and Ni. After the spray impregnation, divide the sample into three parts on average. The first sample is directly dried at 120°C for 3 hours and calcined at 480°C for 2 hours. The obtained catalyst is designated as Z4 ; The second sample was cured for 1h, and after the same post-treatment steps as the catalyst Z4, the prepared catalyst was marked as Z5; the third sample was kept for 3 hours, and the prepared catalyst was marked as Z6 after the same post-treatment steps as the catalyst Z4 .
[0095] Weigh 1.0 g of malic acid, stir and dissolve in 6 g of ethanol to prepare wetting solu...
Embodiment 3
[0097] Weigh 3.5g each of citric acid and malonic acid, stir and dissolve in 20g water to prepare wetting solution I. Take 100g 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 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 B5.
[0098] Weigh 2 g 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 Z7.
[0099] The Z7 sample was spray-impregnated with an equal volume of impregnation solution containing W and Ni, dried directly at 120°C for 3 hours, and calcined at 480°C for 2 hours. The obtained catalyst wa...
