COMPOUND OXIDE CATALYST AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a compound oxide catalyst to manufacture industrially excellent acrolein and acrylic acid.

SOLUTION: An excellent catalytic characteristics can be obtained: in the case that the specific surface area of a compound oxide catalyst containing Mo, Bi as the essential components is 5 to 25 m2/g; that the pore volume stays within 0.2 to 0.7 cc/g; and that the catalyst has such a pore diameter distribution that the pore volume occupied by the pore where the pore diameter is 0.03 to 0.1 μm is 30% or more of the total pore volume, the pore volume occupied by the pore where the pore diameter is 0.1 to 1 μm is 20% or more of the total pore volume and the percentage of the pore diameter of less than 0.03 μm is 10% or less.
