Embodiment 1
[0036] would be equivalent to 56.7 parts Fe 2 o 3iron oxide red, equivalent to 19.2 parts of Fe 2 o 3 Iron oxide yellow, equivalent to 4.55 parts K 2 Potassium carbonate of O, equivalent to 9.75 parts CeO 2 of cerium oxalate, equivalent to 2.58 parts of WO 3 ammonium tungstate, calcium carbonate equivalent to 2.38 parts of CaO, 3.16 parts of MgFe 2 o 4 , 1.68 parts of MnO 2 and 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 in an oven, bake at 90°C for 2 hours, and bake at 160°C for 3 hours, then put it in a muffle furnace, and bake it at 750°C for 3 hours, then at 920°C for 3 hours to obtain the finished catalyst. The catalyst composition is listed in Table 1. The pore distribution and specific surface area of ...
