If W/O emulsified oil was applied as FCC feed stock, with the effect of secondary atomization and molecular depolymerization, atomization situation of feed stock could be improved greatly, and the yields of coke and dry gas could be decreased. In this paper, the procedure of feed stock of FCC emulsification was studied, which included selection and mixture of emulsifier and emulsification conditions. The results show that alkylphenol ethoxylate (M 2) has satisfying emulsification ability. Stability of emulsified oil could be increased by mixture of emulsifier. Suitable quantity of water and emulsifier added were w water =0.10～0.15 and w emulsifier =0.001～0.001 25 respectively, and emulsification operation temperature was 70 °C ～80 °C . The diameter of water droplets distributed from 5μm to 10μm, and the separation time of water and oil could achieve as great as 14 days with the emulsification system temperature at 80 °C .
