preparation example Construction

[0028] According to another aspect of the present invention, there is provided a method for preparing a diesel emulsifier, comprising the following steps: directly mixing and stirring ammonium oleate with an alcohol solvent to obtain a diesel emulsifier; or mixing oleic acid with a mass ratio concentration of 28% ~30% concentrated ammonia water is mixed at a volume ratio of 7:1~1:3, stirred, and heated to 130°C~170°C to obtain ammonium oleate, and alcohol solvent is added dropwise to ammonium oleate to obtain a diesel emulsifier; Among them, the content of ammonium oleate accounts for 40%-90% by volume of the diesel emulsifier; the content of alcohol solvent accounts for 10%-60% by volume of the diesel emulsifier.

[0029] Oleic acid is an unsaturated fatty acid containing 18 carbon atoms and a double bond. It is not a surfactant itself, but is used as a raw material for the production of non-ionic surfactants. It is produced by reacting oleic acid with concentrated ammonia wat...

[0043] At room temperature, add the diesel emulsifiers in Examples 1-5 into 0# diesel respectively, stir evenly on a magnetic stirrer, that is, after the solution is clarified, quickly stir while adding distilled water, and observe that the solution changes from clarification to turbidity , Stir for a while and the solution becomes clear again, then add water while stirring, the solution changes from clear → turbid → clear → turbid → clear, until the last drop of water is added and white flocculent precipitates appear, so that a transparent and clear oily emulsification can be made For diesel fuel, calculate the total volume of water added to the system before adding the last drop of water, and then calculate the maximum water mixing amount (volume fraction) added to the system. See Table 2 for specific data.

Abstract

The invention discloses a diesel oil emulsifier and a preparation method thereof, and emulsified diesel oil containing the same and a preparation method thereof. The diesel oil emulsifier comprises ammonium oleate and an alcohols solvent, wherein the content of the ammonium oleate accounts for, by volume percent, 40-90% of the diesel oil emulsifier, and the content of the alcohols solvent accounts for, by volume percent, 10-60% of the diesel oil emulsifier. The obtained emulsified diesel oil is transparent and clear in appearance like pure diesel oil in color, and is stable in performance without layering, and the water mixing ratio can reach 19% to the maximum; and the diesel oil emulsifier has the advantages of being short in emulsification time, high in emulsification efficiency, low in corrosion and abrasion to an internal combustion engine, high in adaptability to water quality, wide in source, low in price and provided with great popularization and application values.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a diesel emulsifier, a preparation method thereof, and an emulsified diesel oil containing the emulsifier and a preparation method thereof. Background technique [0002] With the rapid development of my country's industry, agriculture, and transportation, the demand for diesel is increasing day by day, but my country's oil production is insufficient, so my country's dependence on imported oil is increasing year by year. How to make full use of existing resources, develop energy-saving technologies, and reduce waste has aroused people's great attention. It is an important way to reduce fuel consumption and control exhaust emissions by formulating ordinary diesel oil into emulsified diesel oil. It has demonstrated its remarkable advantages in terms of saving fuel and improving environmental pollution. At present, emulsification technology has penetrated into the fields of daily ch...
