Abstract The utilization of Fluid Catalytic Cracking (FCC) slurry oil and the main purification technologies were introduced, and the furfural extraction and filtration technology for the separation of catalyst powder from FCC slurry oil was studied. The experimental results showed that over 95 percent of the catalyst powder could be removed by furfural extraction when the extraction temperature was 60 ��, the ratio of catalyst to oil was 2.5:1.0,and the residence time was 25 min.The remained 5 percent of the catalyst powder could be removed through filteration.The extracted oil would not be necessary to remove catalyst powder when it was used as stock feed of catalytic cracking, while the catalyst powder could be filtered due to its low viscosity when it was used as stock feed of catalytic hydrogenation or was for sale.
