Abstract: The composition and clarification methods of fluid catalytic cracking （FCC）slurry are summarized，and the progress of FCC slurry utilization in the fields of petroleum processing and petrochemical industry is introduced in this paper. The role of slurry in asphalt modification，co-processing with coal for asphalt modifier，solvent deasphalting，intensified distillation，visbreaking and delayed coking technology is discussed. Deep separation technologies of FCC slurry are presented，and the application of separated components is presented. In the end，the prospect of slurry utilization is also predicted.
