| titleOfInvention | Composite oxide catalyst and method for producing conjugated diene |
| abstract | A composite oxide catalyst used when a conjugated diene is produced by a gas phase catalytic oxidative dehydrogenation reaction using a monoolefin having 4 or more carbon atoms as a raw material, and the raw material is used even under conditions where the raw material contacts with the catalyst in a short time The present invention provides a high-strength composite oxide catalyst that has an excellent conversion rate, can improve selectivity and yield, and can stably perform gas phase catalytic oxidative dehydrogenation for a long period of time. A composite oxide catalyst for use in a gas phase catalytic oxidative dehydrogenation reaction of a monoolefin having 4 or more carbon atoms, comprising a plurality of specific element oxides, and having a specific surface area of 5 m 2 / g to 25 m. 2 / g, pore volume ratio of 0.20 ml / g to 0.50 ml / g, pore volume ratio of 0.1 μm to 1.0 μm, 50% to 68% of total pore volume, same pore diameter A composite oxide catalyst in which the proportion of pore volume of less than 0.1 μm is 27% to 50% of the total pore volume.
