Example Embodiment
[0038] Example 1
[0039] Measure 140mL of absolute ethanol and pour it into a beaker. Measure 30.7mL of butyl titanate and slowly pour into the absolute ethanol. Stir continuously at medium speed on a magnetic stirrer; use a dropper to measure 3mL of ice during the above stirring process. Add acetic acid drop by drop, and continue to stir to form a transparent solution A; weigh 2.5g nickel nitrate hexahydrate, 1.6g cerium nitrate hexahydrate, and 12.8g magnesium nitrate hexahydrate, mix and dissolve in 20mL deionized water, high speed on a magnetic stirrer Stir; In the above stirring process, add 2mL of dilute nitric acid dropwise with a dropper and continue stirring to make solution B; slowly pour solution B into solution A during stirring, and stir at high speed for 15 minutes to form a brown gel, and then Leave it to age in a water bath at a constant temperature of 60°C for 2h; place it in a drying oven at 110°C for 24h. After drying, ground into large particles; put the gro...

[0046] Example 3
[0047] Weigh 2.5g nickel nitrate hexahydrate, 1.6g cerium nitrate hexahydrate, 12.8g magnesium nitrate hexahydrate, 32g aluminum nitrate nonahydrate, mix and dissolve in 70mL deionized water, place on a magnetic stirrer and stir at high speed to form solution A; Take 22.2g of sodium hydroxide, dissolve it in 70mL of deionized water, stir at high speed on a magnetic stirrer to form solution B; in the process of high speed stirring, use a dropper to drop B solution into A solution until the precipitation is complete. The precipitate was washed and filtered until the filtrate was neutral. The precipitate was placed in a drying box and dried at 110°C for 24 hours. After drying, ground into large particles; put the ground large particles in a muffle furnace at 700°C for 3 hours, and after the temperature drops to room temperature, take out the catalyst particles that are ground and sieved to the desired particle size. The catalyst is called Ni-Ce-MgO-Al 2 O 3 -1. ...
