Embodiment 1
[0023] 1. Carrier pre-baking:
[0024] Weigh 70g clover-type φ1.5mmγ-Al 2 o 3 , pre-calcined at 800° C. for 4 hours, and naturally cooled to room temperature to obtain a pre-calcined carrier.
[0025] 2. Impregnated active components:
[0026] Weigh 110g of copper nitrate trihydrate, 78g of nickel nitrate hexahydrate, 1.6g of cobalt nitrate hexahydrate, and add them to 120ml of water to dissolve, and circulate the prepared solution to impregnate the pre-calcined carrier obtained in 1. The solution is pumped into the dipping kettle, soaked at 40°C for 10 minutes, and released, then pumped into the dipping kettle, and soaked in circulation for 24 hours. After filtration, it was dried at 60°C for 2 hours, then dried at 120°C for 8 hours, and finally calcined at 450°C for 4 hours, and cooled to room temperature naturally to obtain the required catalyst. The chemical composition of the catalyst was analyzed in Table 1.

Embodiment 2
[0030] 1. Carrier pre-baking:
[0031] Weigh 70g clover-type φ1.5mmγ-Al 2 o 3 , pre-calcined at 800° C. for 4 hours, and naturally cooled to room temperature to obtain a pre-calcined carrier.
[0032] 2. Impregnated active components:
[0033] Weigh 100g of copper nitrate trihydrate, 110g of nickel nitrate hexahydrate, 34.0g of cobalt nitrate hexahydrate, and add them to 90ml of water to dissolve them, and use the prepared solution to circulate and impregnate the pre-calcined carrier obtained from 1 at 50°C for 12 hours , the dipping process is the same as in Example 1. After filtering, dry at 60°C for 2 hours, then dry at 120°C for 4 hours, and finally bake at 500°C for 4 hours, and cool down to room temperature naturally to obtain the required catalyst. The chemical composition of the catalyst is shown in Table 1.
[0034] 3. Catalyst evaluation and application:
[0035] Take the required amount of the catalyst prepared as above, put it into a 100ml fixed-bed reactor, p...
Embodiment 3
[0037] 1. Carrier pre-baking:
[0038] Weigh 70g clover-type φ1.5mmγ-Al 2 o 3 , pre-calcined at 700° C. for 4 hours, and naturally cooled to room temperature to obtain a pre-calcined carrier.
[0039] 2. Impregnated active components:
[0040] Weigh 170g copper nitrate trihydrate and 220g nickel nitrate hexahydrate, dissolve them in 90ml water, and use the prepared solution to cyclically impregnate the pre-calcined carrier obtained in 1 at 60°C for 12 hours. The impregnation process is the same as in Example 1. After filtering, dry at 60°C for 2 hours, then dry at 120°C for 8 hours, and finally bake at 550°C for 4 hours, and cool down to room temperature naturally to obtain the required catalyst.
[0041] 3. Catalyst evaluation and application:
[0042] Take the required amount of catalyst prepared as above, put it into a 100ml fixed-bed reactor, pass through the hydrogen gas at 600ml / min after passing the nitrogen replacement, and reduce it under the hydrogen flow at 280-...
