| abstract | When producing a corresponding unsaturated aldehyde and / or unsaturated carboxylic acid by subjecting an olefin or tertiary butanol to a gas phase catalytic oxidation reaction, pressure loss can be reduced, thereby suppressing coking, Providing a catalyst group capable of producing a corresponding unsaturated aldehyde and / or unsaturated carboxylic acid in high yield. A catalyst group including 200 or more ring-shaped catalysts having a straight body portion A and a cavity portion B, which is used when producing an unsaturated aldehyde and / or an unsaturated carboxylic acid, the following (1) And a group of catalyst particles satisfying (2). (1) The length 3 of the straight body portion is shorter than the length 7 of the cavity portion, and the straight body portion A includes a surface including one end portion C of the cavity portion B and the other end portion. A catalyst (A) which is between the surface and is linear and / or curved at least at one end C from the end of the straight body to the end C of the cavity including. (2) The upward ratio according to the shaking test of the catalyst group is 70% or less. [Selection] Figure 1 |
