Embodiment 1
[0019] Weigh 96.64g Cu(NO 3 ) 2 ·3H 2 O, 297.5g Zn(NO 3 ) 2 ·6H 2 O and 225.08g Al(NO 3 ) 3 9H 2 O was dissolved in 3L deionized water, at room temperature, with 1mol / L Na 2 CO 3 The aqueous solution was added dropwise and continuously stirred vigorously. When the pH value was between 7 and 9, the dropwise addition was stopped, and then the obtained precipitate was washed to remove Na + After that, the precipitate was dried overnight at 90°C, calcined at 250°C for 6h, shaped and crushed to obtain 20-40 mesh catalyst main particles C1; weigh 0.256g Mg(NO 3 ) 2 ·6H 2 Dissolve O in 100mL deionized water to make a 0.010mol / L solution, measure 4mL of C1 particles and put them into 10mL of the above solution, add 0.1mol / mL ammonia water dropwise to the solution at 30°C with stirring until the pH is between After 8~9, the catalyst was dried in an oven at 90°C for 3h, and then calcined in a muffle furnace at 200°C for 3h, and finally the catalyst was labeled as Mg-C1...
Embodiment 2
[0022] Weigh 193.28g Cu(NO 3 ) 2 ·3H 2 O, 119.00g Zn(NO 3 ) 2 ·6H 2 O and 300.11g Al(NO 3 ) 3 9H 2 O was dissolved in 3L deionized water at 40°C with 1mol / L NaHCO 3 The aqueous solution was added dropwise and continuously stirred vigorously. When the pH value was between 7 and 9, the dropwise addition was stopped, and then the obtained precipitate was washed to remove Na + After that, the precipitate was dried overnight at 90°C, calcined at 300°C for 4h, shaped and crushed to obtain 20-40 mesh catalyst main particles C2; weigh 0.262g Ba(NO 3 ) 2 Dissolve in 200mL deionized water to make a 0.005mol / L solution, measure 4mL of C2 particles and put it into 10mL of the above solution, add 0.5mol / mL ammonia water dropwise to the solution at 40°C with stirring until the pH is between 8 After ~9, the catalyst was dried in an oven at 90°C for 3h, and then calcined in a muffle furnace at 250°C for 3h, and finally the catalyst was labeled as Ba-C2.

Embodiment 3
[0025] Weigh 0.214g Zr(NO 3 ) 4 ·5H 2 O was dissolved in 500mL deionized water to make a 0.001mol / L solution, and 4mL of C1 particles were weighed and put into 10mL of the above solution, and 0.1mol / mL Na 2 CO 3 After the aqueous solution was added dropwise to the solution until the pH was between 8 and 9, the catalyst was washed with deionized water to remove Na + , the catalyst was dried in an oven at 90°C for 3h, and then calcined in a muffle furnace at 200°C for 3h to obtain a catalyst marked as Mg-C1.
[0026] The catalytic performance was compared with the 20-40 mesh C1 catalyst under the following conditions. Except that the final reduction temperature was 260°C and the catalyst evaluation temperature was 260°C, other performance comparison conditions were the same as in Example 1. The results are shown in Table 1.
