The ZSM-5 and Y zeolites were pulverized by air stream to form fine particles. The particle size distribution,surface area,IR and TPD spectra were determined for both of the raw and fine particles.The catalytic activity of fine particle in cumene cracking was compared with the raw on pulse microreactor connected on line with a chromatograph.After ZSM-5 and Y zeolites being pulverized,their B and L acid amount increased and catalytic activity improved apparently.
