Abstract: FCC slurry is of low value when it is used as fuel component and its high value application is of interest in recent years. The processes of high value utilizations of FCC slurry were reviewed. Especially,the industrialized processes of FCC blending with coke feed,blending with reduced crude to get more gas oil,blending with vacuum residue as feed of solvent deasphalting and distilling units to get asphaltenes were described. Meanwhile,the research results of processing of slurry with coal,solvent extraction of slurry to get aromatics rich fractions to produce chemical products and thermal cracking of slurry to get asphaltene upgrading component were described. The features of the processes were described also. For high value utilizations of slurry,blending process is reliable and easy to accomplish,but the value added is not obvious and the process is restricted by the existed unit of refinery and the volume of blending. The value increase of other processes is obvious,but additional units and investment are required. Therefore the processing of slurry by collection will be a valuable method in large scale utilization.

Key words: catalytic cracking, slurry, higher value application
