Daqing Petrochemical Plant FCC slurry as raw material, furfural as a separation of solvent, this method can effectively separate the cracking part and the faction containing mass aromatics in slurry. It was studied the influence of extraction temperature, catalyst to oil ratio and residence time in refined effects. The results show that FCC slurry is separated well in the extraction temperature of 60 ℃, catalyst to oil ratio of 2∶1, at 30 min retention time. The content of saturated hydrocarbons in refined oil up to 80%, has the good FCC performance. The extracting oil can be used as the blending component of the aromatic rubber filling oil.
