Compared with prior art, the beneficial effects of the present invention are:
The present invention is compounded using two kinds of higher surfactants of viscosity of Span80 and Tween60, solves the prior art
Middle surfactant and low-carbon alcohols cosurfactant are used in compounding brought micro emulsion light-liquid interfacial tension reduction and microemulsion
The too low technical problem of system viscosity.Microemulsified F-T diesel oil disclosed in this invention has good kinematic viscosity, while and F-
T diesel oil is discharged compared to exhaust gas smoke and NO discharge capacity is put significantly reduces, and exhaust emission is small, has more preferably comprehensive performance, symbol
Close the relevant criterion of national derv fuel.
Microemulsified F-T diesel fuel constituents of the present invention are simple, and raw material is cheap and easy to get, microemulsified F-T bavin W/O
Reach 9.2~23.6% with the total content of surfactant；And diesel engine is still in content range disclosed in this invention
With preferable dynamic property；The price and surfactant price of water are below F-T diesel oil, greatly reduce using F-T bavin
The cost of oil.Also, preparation method is simple, without using special installation, is conducive to preparation of industrialization and implements.
