Abstract: Effects of magnetic field intensity and carrier air flowrate on the magnetic separation of fluid catalytic cracking(FCC) catalyst with a high gradient magnetic separator(HGMS) were studied. The activities of the equilibrium catalyst,the magnetic particles and the nonmagnetic particles were evaluated in a fixed bed microreactor. The results showed that the catalyst contaminated by heavy metal can be selectively separated by means of HGMS at magnetic field intensity 0.5T and carrier air flowrate 0.3m·s^-1, and the catalyst contaminated lightly retained high catalytic activity.
