Abstract

The invention discloses a microemulsified water-containing ethanol gasoline and a blending method thereof, and relates to the technical field of chemical fuels; the invention uses sorbitan monooleate, sorbitan trioleate and polyoxyethylene sorbitan monohard A mixture of esters is used as a lipophilic emulsifier, and octylphenol polyoxyethylene ether with a degree of polymerization of 10, octylphenol polyoxyethylene ether with a degree of polymerization of 4, isobutanol and isopropanol are used as a hydrophilic emulsifier. emulsifier, then use lipophilic and hydrophilic emulsifiers to emulsify gasoline and water-containing ethanol solution, and finally mix the emulsified gasoline and emulsified water-containing ethanol solution, so that the system forms a stable water-in-oil emulsion, which improves the water content of microemulsion The stability of ethanol gasoline, microemulsified ethanol gasoline with water in the temperature range of -10 ℃ ~ 40 ℃ can be maintained for more than 30 days without stratification.

Description

technical field [0001] The invention relates to the technical field of automobile substitute fuels, in particular to a microemulsified water-containing ethanol gasoline and a blending method thereof. Background technique [0002] As a new type of clean fuel, micro-emulsified ethanol gasoline with water has far lower requirements on the rectification process than absolute ethanol. Therefore, compared with ethanol gasoline, the production cost of micro-emulsified ethanol gasoline can be greatly reduced. reduce. However, because gasoline is insoluble in water, microemulsified water-containing ethanol gasoline is prone to phase separation during preparation, storage, transportation, and use, which makes the energy density of the fuel in the fuel tank uneven, the combustion properties deteriorate, and the car is prone to malfunction. . [0003] The existing microemulsified ethanol gasoline with water is like "a kind of ethanol gasoline with water and its preparation method" (pa...
