Embodiment 1
[0038] would be equivalent to 58.37 parts Fe 2 o 3 iron oxide red, equivalent to 18.18 parts of Fe 2 o 3 Iron oxide yellow, equivalent to 7.7 parts K 2 Potassium carbonate of O, equivalent to 7.21 parts of CeO 2 of cerium oxalate, equivalent to 2.58 parts of WO 3 ammonium tungstate, barium hydroxide equivalent to 1.12 parts of BaO, 3.16 parts of ZrO 2 , 1.68 copies of Dy 2 o 3and 5.69 parts of sodium carboxymethylcellulose were stirred in a kneader for 1.5 hours, added deionized water accounting for 25% of the total weight of the catalyst raw material, stirred for 0.5 hour, took out the extruded strips, and extruded into particles with a diameter of 3 mm and a length of 6 mm. Put it into an oven, bake at 60°C for 2 hours, and bake at 130°C for 3 hours, then place it in a muffle furnace, and bake it at 550°C for 3 hours, and then at 920°C for 3 hours to obtain a finished catalyst. The composition of the catalyst is listed in Table 1.
