Abstract: Taking 60# Fischer-Tropsch wax as raw material,Span and Tween series as main emulsifiers,Fischer-Tropsch wax emulsion is prepared via the agent-in-oil method.The influences of the types of emulsifiers,emulsification temperature,stirring rate,dripping speed and emulsifier content on the performance of the prepared emulsion are explored.It is found that a submicron Fischer-Tropsch wax emulsion with high stability and high dispersibility is obtained when emulsification temperature is at 80℃,stirring rate is 900 r·min-1,water phase is dropped at a speed of 1 mL·min-1 and emulsification spends 30 min.The average particle size of the emulsion is controlled at about 200 nm,the wax content is 35.71%,and the viscosity is 2-5 mPa·s.Through appropriate selection of emulsifiers and reasonable doping of co-emulsifiers,the using amount of emulsifiers can be reduced to a certain extent while ensuring that other properties of the emulsion are not subject to large fluctuations.
