Abstract
Provided is an ammoxidation catalyst for propylene, a manufacturing method of the same, and an ammoxidation method of propylene using the same. Specifically, according to one embodiment of the invention, there is provided a catalyst having a structure in which metal oxide is supported on a silica carrier, having narrow particle size distribution, and having excellent attrition loss. The catalyst may have a D50 particle diameter of 30 to 300 μm, and D10 particle diameter, D50 particle diameter and D90 particle diameter may satisfy the relationship (D90−D10)/D50<2.0. The catalyst may have a chemical formula MoBiFeCoKO, where a is 0.1 to 5, b is 0.1 to 5, c is 0.01 to 10, d is 0.01 to 2, and x is 24 to 48.
