Embodiment 1
[0038] (1) The weight percent content of selected zirconia in the whole catalyst is 5%;
[0039] (2) Weigh 5 grams of SiO 2, use deionized water to determine the volume of solution required for equal-volume impregnation to be 10 milliliters;
[0040] (3) Weigh 0.69 grams of ZrOCl 2 ·8H 2 O was dissolved in 10 ml of deionized water to prepare an impregnating solution;
[0041] (4) Add the impregnation solution prepared in step (3) dropwise to 5 grams of SiO taken by (2) 2 On, equal-volume impregnation for 24 hours, and vacuum-dried the impregnated carrier in a constant temperature water bath at 60°C for 2 hours;
[0042] (5) Calcining the impregnated and dried support obtained in step (4) in an air atmosphere at 500° C. in a muffle furnace for 5 hours to obtain the required supported zirconia catalyst of the present invention.
Embodiment 2
[0044] (1) The weight percent content of selected zirconia in the whole catalyst is 3%;
[0045] (2) Take 5 grams of SiO 2 , use deionized water to determine the volume of solution required for equal-volume impregnation to be 10 milliliters;
[0046] (3) Weigh 2 grams of ZrOCl 2 ·8H 2 O was dissolved in 50 ml of deionized water to prepare an impregnating solution;
[0047] (4) with 5 grams of SiO that (2) step claims 2 Place in the impregnating solution prepared in step (3), heat to 90°C, impregnate excessively for 24 hours, obtain the impregnated carrier by vacuum filtration, and vacuum-dry the impregnated carrier at 60°C for 3 hours;
[0048] (5) Calcining the impregnated and dried support obtained in step (4) in an air atmosphere at 500° C. in a muffle furnace for 5 hours to obtain the required supported zirconia catalyst of the present invention.
Embodiment 3-5
[0050] The preparation method is the same as in Example 1, except that the calcination temperatures in step (5) are changed to 400°C, 600°C, and 700°C, respectively, to prepare the respective required supported zirconia catalysts of the present invention.
