PROCESS FOR PRODUCING ANTIMONY-CONTAINING OXIDE CATALYST SUPPORTED ON SILICA FOR USE IN FLUIDIZED BED REACTION |
摘要 |
A process for producing an antimony-containing oxide catalyst supported on silica for use in a fluidized bed reaction is described, by the steps of preparing a slurry containing an antimony compound, a polyvalent metal compound, and silica sol as the essential ingredients, heat treating the slurry at a pH of 7 or less and at a temperature of 40 DEG C. or higher, and thereafter spray-drying the slurry and calcining the dried particles, wherein said silica sol has a multi-peak particle size distribution profile that is derived by using a mixture of silica sol A in an amount corresponding to form 10 to 90 wt % of the total silica in the catalyst and silica sol B in an amount corresponding to 90 to 10 wt % of the total silica in the catalyst, with silica sols A and B having different average particle sizes, provided that the relations 3<da<100 and 0.1<da/db<0.9 are satisfied by da (m mu ), the average particle size of silica sol A, and db (m mu ), the average particle size of silica sol B. |
