英文摘要：

The catalyst particle in slurry is the key factor that restricts the utilization of slurry, therefore catalyst removal in fluid catalytic cracking（FCC） slurry becomes a problem which needs to be solved urgently. Technologies of catalyst removal in FCC slurry comprehensively are introduced, and gravitational sedimentation, filtration separation, centrifugal separation, electrostatic separation and other methods are summarized respectively. Moreover, the advantages and disadvantages of above methods are reviewed and analyzed. The prospect for development of catalyst removal in FCC slurry is put forward.
