Abstract: |
The invention discloses a method for preparing the rare-earth compound oxide catalyst, wherein the component is the composite oxides of ZrO2 and CeO2, and the molar ratio of the Zr and Ce is 1:1~1:11. The preparing method comprises the following steps: a) formulating the mixed solution of zircon salt and cerium salt, b) dropping the solution slowly to the alkaline solution which has been stirred vigorously, getting the gelatin deposit and filtering, c) dispersing the deposit again into the deionized water, adjusting the PH to alkalinity, refluxing in the hot alkali liquor, drying and baking and getting the catalyst. |
