Abstract
The present invention relates to a catalyst having a value of a sphericity parameter SPHT3 obtained by particle shape measurement by a dynamic image analysis method of 0.9820 or less. Here, the sphericity parameter SPHT3 is a value obtained by the following equation (I). SPHT3=4πA/P2 . . . (I) In the equation (I). A is the area of a particle photographed by the dynamic image analysis method, and P is the perimeter of the particle.
