Particulate catalyst for use in a fluidized bed

摘要

The present invention provides a fluidized bed catalyst for the synthetic reaction of organic compounds which has a reduced catalyst loss. A fluidized bed catalyst for organic compound synthetic reaction, characterized in that 90% or more of the catalyst particles is in the range of 5 - 500 mu m on the weight-based particle size distribution and 90% or more of the 20 - 75 mu m particles has a crushing strength which satisfies the following equation: $wherein\; CS\; represents\; a\; crushing\; strength\; Äg-weight/particleÜ,\; A\; represents\; a\; constant\; 0.001,\; d\; represents\; a\; particle\; diameter\; Ä\; mu\; mÜ,\; and\; alpha\; represents\; a\; constant\; 2.$
