| titleOfInvention | Method for producing composite oxide catalyst |
| abstract | As a composite oxide catalyst used in the production of acrolein and acrylic acid by vapor phase catalytic oxidation of propylene, the conversion ratio of raw materials is excellent even under conditions where the load of the composite oxide catalyst is high, and acrolein and An object of the present invention is to provide a composite oxide catalyst having a high selectivity of acrylic acid and capable of improving the yield. In a method for producing a composite oxide catalyst containing Mo, Bi, Fe, Si, and Co and / or Ni as catalytic active elements, At least Mo source compound, Fe source compound, Si source compound, and Co source compound and / or Ni source compound are integrated and heated in an aqueous system to form a catalyst precursor. Manufacture of a composite oxide catalyst prepared through a pre-process and a post-process using at least the catalyst precursor, Mo source compound and Bi source compound integrated and heated in an aqueous system to form a catalytically active component A method, The atomic ratio of Bi in the Bi source compound in the subsequent step to the sum of Mo in the Mo source compound in the previous step and Mo in the Mo source compound in the subsequent step is 0.22 or more and 0.42 or less. And a method for producing a composite oxide catalyst in which the atomic ratio of Bi in the Bi source compound in the subsequent step to Mo in the Mo source compound in the subsequent step is 0.71 to 1.68.
