The wax residue oil emulsified as a catalytic cracking feedstock, under the action of micro-explosion can significantly improve the feedstock atomization conditions, reduce coking and dry gas yield. The emulsification process of emulsified oil and physical properties of emulsified oil were studied, including the selection of emulsifier and the determination of emulsification conditions. The changes of physical properties such as surface tension, interfacial tension and viscosity before and after emulsification of feedstock oil were analyzed and analyzed The reason for these changes. The results show that the alkylphenol ethoxylates M-2-based ternary complex emulsifier has good emulsifying properties; in the range of 60 ~ 90 ° C, the interfacial tension of emulsified feedstock oil is lower than the surface tension of feedstock oil 67.0 4% ~ 87.77%
