Examples
Embodiment 1
[0020] Example 1 Catalyst 1
[0021] Add 8.3g of spherical γ-Al to the prepared LaCe mixed rare earth nitrate solution 2 o 3 , impregnated at room temperature for 24 hours, evaporated to dryness in a water bath at 80°C, dried at 110°C for 12 hours, and roasted at 800°C for 4 hours. 3 ) 2 ·6H 2 O solution, soaked at room temperature for 24 hours, evaporated to dryness in a water bath at 80°C, dried at 110°C for 12 hours, and calcined at 800°C for 4 hours to obtain a finished catalyst.
Embodiment 2
[0022] Example 2 Catalyst 2
[0023] The preparation process is the same as catalyst 1, the only difference is that the mixed rare earth is LaY mixed rare earth.
Embodiment 3
[0024] Example 3 Catalyst 3
[0025] The preparation process is the same as that of Catalyst 1, the only difference is that the mixed rare earth is LaPr mixed rare earth.
