Embodiment 1
[0016] Take by weighing two parts of silica sol 100g carrier, one part is modified (recorded as SiO 2 (M)), one unmodified (denoted as SiO 2 (W). According to 25wt%Cu+10wt%Zn / SiO 2 content preparation catalyst, the steps are as follows: select copper nitrate, prepare impregnation solution according to the Cu loading amount, prepare the impregnation solution according to the loading amount, and prepare the modified SiO 2 After the carrier was soaked in the solution for 24 hours, it was vacuum-dried for 8 hours to obtain a solid. Choose ZnCl 2 According to the Zn load, the impregnating solution is formulated. In order to prevent metal ions from being hydrolyzed to form hydroxides or oxides, a small amount of hydrochloric acid is added to the impregnating solution to make the pH of the impregnating solution = 5-6. Soak for 10 hours, dry it in a water bath to become a solid after fully absorbed, then dry the solid at 120°C for 8 hours, bake at 650°C for 6 hours, and then use a...
Embodiment 2
[0018] Weigh two parts of 100g modified silica sol carrier, according to 35wt% Cu+15wt% Zn / SiO 2 Content preparation catalyst, its steps are as follows: select cupric chloride, prepare impregnating liquid according to Cu loading amount, load amount is formulated into impregnating liquid, after immersing the prepared modified silica sol carrier in this solution for 10 hours, vacuum-dry for 6 hours. hours to get solids. Choose Zn(NO 3 ) 3 , according to the loading capacity of Ag, the impregnating solution was formulated. In order to prevent metal ions from being hydrolyzed to form hydroxide or oxide precipitation, a small amount of nitric acid was added to the impregnating solution to make the pH of the impregnating solution = 6.5, and then the modified silica sol carrier was impregnated Soak in the solution for 10 hours, dry it in a water bath after being fully absorbed, and then dry the solid at 120°C for 6 hours, and roast it at 500°C for 6 hours, respectively use nitrogen...
