Embodiment 1
[0040] This embodiment is a supported catalyst 20% Ni-SiO 2 (30wt% safflower powder (SBG)).
[0041] Weigh 34.67g tetraethyl orthosilicate and set aside. At room temperature, add 9.9094g Ni(NO 3 ) 2 ·6H 2 O, a certain amount of ultrapure water, 3.0697g of scallop powder, stirred at 120°C for 24 hours, dried at 120°C for 24 hours, put the dried sample in a muffle furnace, calcined at 600°C for 4 hours, and the heating rate was 10°C / min , to get the supported catalyst Ni-SiO 2 , the loading amount of Ni is 20%, which is recorded as 20% Ni-SiO 2 (30 wt% SBG).
[0042] The specific surface area BET of the supported catalyst of this embodiment is 371.7825m 2 g -1 .
Embodiment 2
[0044] This embodiment is a supported catalyst 20% Ni-SiO 2 (0 wt% SBG) preparation.
[0045] The difference between the present embodiment and embodiment 1 is only that the consumption of the kale powder is 0 g.
[0046] The specific surface area BET of the supported catalyst of this embodiment is 207.4457m 2 g-1 .
Embodiment 3
[0048] This embodiment is a supported catalyst 20% Ni-SiO 2 (3 wt% SBG) preparation.
[0049] The difference between this embodiment and embodiment 1 is only that the consumption of the scallop powder is 0.3069g.
