Stability of Aqueous Microemulsions In Motor Fuels

The effect of additives — surfactants (SF) — on the water–separating properties of jet fuels. These additives significantly worsen thefuel–water reaction index. Methods of fuel flooding simulating the conditions of formation of water–fuel microemulsions during storage, shipment, and use are developed. Data on the effect of the nature of the fuel on the settling rate of microemulsions are reported. Water–fuel microemulsions form when temperature fluctuations are stable for more than 100 h, which favors formation of aqueous sludges in aircraft tanks.
