Abstract

The invention discloses a reversed micelle micro-emulsion and a preparation method thereof, and a reversed micelle biological oil micro-emulsion and a preparation method thereof, wherein the reversedmicelle micro-emulsion comprises diesel oil, a surfactant, a co-surfactant and ethanol, the co-surfactant content in the reversed micelle micro-emulsion is 0.07-0.15 mL / mL, the ethanol content in thereversed micelle micro-emulsion is 0-0.16 mL / mL, a molar volume ratio of the surfactant to the diesel oil is 0.15-0.50 mol:1 L, and the reversed micelle biological oil micro-emulsion is prepared fromthe reversed micelle micro-emulsion and biological oil. According to the present invention, the biological oil is subjected to solubilization and quality upgrading through the reversed micelle micro-emulsion using the diesel oil as the continuous phase, such that the limitation of the biological oil in the diesel engine is reduced through the constructed reversed micelle biological oil micro-emulsion, and the potential of the biological oil as the transportation fuel is improved.

Description

technical field [0001] The invention belongs to the field of petroleum energy, and in particular relates to a reverse micellar microemulsion and a preparation method thereof, a reverse micellar bio-oil microemulsion and a preparation method thereof. Background technique [0002] In recent years, my country's diesel consumption has been increasing, and the contradiction between supply and demand has led to rising oil prices. In addition, the massive discharge of pollutants caused by the incomplete combustion of diesel has caused harmful effects on humans and the environment that cannot be underestimated. Therefore, it is becoming more and more important to find a renewable green energy source as an alternative fuel. [0003] Renewable biomass energy such as agricultural and forestry residues, aquatic and terrestrial vegetable oils, and domestic and industrial wastes can be liquefied to obtain liquid fuel bio-oil. Among them, the liquefaction of municipal sludge to form bio-...
