Problems solved by technology

[0002] Microemulsified diesel oil has come out for decades, but it has not been popularized and applied so far. Its reason is that there are following deficiencies in the production method of microemulsified diesel oil in the prior art: 1. Poor stability and short shelf life: the microemulsified diesel oil developed by various countries in the world at present Most diesel oil is a white emulsion, the particle diameter of the water phase is 0.01-0.1mm, and the storage period is generally only 2-10 days. It cannot be used as commercial oil turnover, which brings limitations to popularization and use.
2. The cost of emulsifier is high: although it has a good fuel-saving effect, it does not save money, and the direct economic benefits for users are not obvious
Due to the high unit price of this type of emulsifier, the production cost remains high, and the industrial application value is not large
3. Complex equipment, large investment, high energy consumption: many use ultrasonic emulsification devices, high-shear mixing equipment, and some even require heating. The investment is large, the energy consumption is high, the production scale is small, and the processing cost is high. difficulty
4. It is also possible to add waste animal and vegetable oil and oil processing waste to mineral diesel. The biodiesel produced by this method has high viscosity and is easy to block the nozzle. The freezing point is not lower than 15°C, and it is useless when the temperature is low.

Description

technical field [0001] The invention belongs to the field of biodiesel, in particular to a microemulsion biodiesel and a preparation method thereof. Background technique [0002] Microemulsified diesel oil has come out for decades, but it has not been popularized and applied so far. Its reason is that there are following deficiencies in the production method of microemulsified diesel oil in the prior art: 1. Poor stability and short shelf life: the microemulsified diesel oil developed by various countries in the world at present Most diesel oil is a white emulsion, the particle diameter of the water phase is 0.01-0.1mm, and the storage period is generally only 2-10 days. It cannot be used as commercial oil turnover, which brings limitations to popularization and use. 2. The cost of emulsifier is high: Although it has a good fuel-saving effect, it does not save money, and the direct economic benefits for users are not obvious. They mainly use Span series, Tween series and ol...
