Embodiment 1
[0037] Weigh 57g of aluminum nitrate, 40.5g of zirconium nitrate, 4.1g of cobalt acetate, and 0.42g of lanthanum nitrate, dissolve them in 500ml of water and stir for 10min to obtain solution A. Weigh 72g of urea, 16ml of ammonia water and dissolve in 500ml of water, then add 14.2g of basic nickel carbonate to obtain solution B. Solution A and solution B were mixed uniformly in an ultrasonic oscillator in parallel flow, the frequency of the ultrasonic wave was 25 kHz, and the mixed solution C was obtained by oscillating for 15 minutes. Move the solution C to a microwave reactor with a filling volume of no more than 80%, heat it at 180°C for 30 minutes, cool it down to room temperature naturally, pour it into a centrifuge for washing, and dry it at 120°C for 24 hours. The obtained catalyst powder was mixed with 0.8g of scallop powder and 0.7g of citric acid, extruded and roasted, heated to 400°C at a rate of 2°C / min, roasted at a constant temperature for 2 hours, and then roast...
Embodiment 2
[0039]Weigh 40.5g of zirconium nitrate, 1.1g of cobalt acetate, 0.85g of lanthanum nitrate, and 39.6g of colloidal silica, dissolve them in 500ml of water and stir for 20min to obtain solution A. Weigh 60g of urea, 12ml of ammonia water and dissolve in 500ml of water, then add 10.5g of basic nickel carbonate to obtain solution B. Solution A and solution B were mixed uniformly in an ultrasonic oscillator in parallel flow, the frequency of the ultrasonic wave was 45 kHz, and the mixed solution C was obtained by oscillating for 20 minutes. Move the solution C to a microwave reactor with a filling volume of no more than 80%, heat it at 160°C for 15 minutes, cool it down to room temperature naturally, pour it into a centrifuge for washing, and dry it in vacuum at 80°C for 36 hours. The obtained catalyst powder was mixed with 0.7 g of scallop powder and 0.6 g of citric acid, extruded and roasted, heated to 400 °C at a rate of 1 °C / min, roasted at a constant temperature for 2 hours, ...
Embodiment 3
[0041] Weigh 104g of aluminum nitrate, 40.5g of zirconium nitrate, 5.9g of cobalt sulfate, and 2.33g of lanthanum nitrate, dissolve them in 500ml of water and stir for 15min to obtain solution A. Weigh 89.7g of urea, 18ml of ammonia water and dissolve in 500ml of water, then add 18.2g of basic nickel carbonate to obtain solution B. Solution A and solution B were mixed uniformly in an ultrasonic oscillator in parallel flow, the frequency of the ultrasonic wave was 30 kHz, and the mixed solution C was obtained by oscillating for 25 minutes. Move the solution C to a microwave reactor with a filling volume of no more than 80%, heat it at 100°C for 60 minutes, cool it down to room temperature naturally, pour it into a centrifuge for washing, and dry it in vacuum at 80°C for 72 hours. The obtained catalyst powder was mixed with 1.2 g of scallop powder and 0.9 g of citric acid, extruded and roasted, heated to 450 ° C at a rate of 2 ° C / min, roasted at a constant temperature for 1 h...
