ZEOLITE-CONTAINING CATALYST, PROCESS FOR PRODUCING THE ZEOLITE-CONTAINING CATALYST, AND PROCESS FOR PRODUCING PROPYLENE

摘要

The present invention provides a zeolite-containing catalyst having excellent shape, fluidity and mechanical strength as a catalyst for a fluidized bed reaction. The present invention provides a zeolite-containing catalyst which is a particulate catalyst containing zeolite and silica, wherein the catalyst has an average particle diameter of 20 to 300 µm and the ratio of the void area in the cross-section of the particle is 30% or less relative to the cross-section area of the particle.
