| titleOfInvention | Composite oxide catalyst, method for producing acrolein and acrylic acid using the same |
| abstract | As a composite oxide catalyst used for gas phase catalytic oxidation using an olefin as a raw material, the raw material is excellent in conversion rate even under conditions where the raw material contacts with the catalyst in a short time, and desired unsaturated aldehyde and unsaturated An object of the present invention is to provide a composite oxide catalyst having excellent strength that can maintain the selectivity of carboxylic acid at a high level, improve the yield, and can stably perform a gas phase catalytic oxidation reaction for a long period of time. A composite oxide catalyst for use in vapor phase catalytic oxidation of olefin, the composite oxide catalyst comprising an oxide of a plurality of specific elements, having a specific surface area of 5 m 2 / g to 25 m 2 / g, The pore volume occupied by pores having a pore volume of 0.20 ml / g to 0.50 ml / g and a pore diameter of 0.1 μm to 1.0 μm in the pore size distribution is the total pores 50% to 68% of the volume and a composite oxide catalyst in which the pore volume occupied by pores having a pore diameter diameter of less than 0.1 μm is 27% to 50% of the total pore volume. [Selection figure] None |
