Problems solved by technology

[0006] Although these formulas can obtain microemulsified biodiesel, there are problems such as excessive emulsifier dosage, poor volatility or too complicated formula.
The microemulsion diesel oil provided by Chinese patent CN102382713 A can significantly reduce the amount of emulsifier, but its microemulsion diesel oil still has problems such as high entropy instability, high viscosity, and low volatility

Abstract

The invention discloses a biodiesel compound emulsifier and its preparation method and application thereof. The adopted microemulsion biodiesel prepared by the invention has advantages of high water content, low viscosity, strong volatility and stability.

Description

technical field [0001] The invention relates to the field of biodiesel, in particular to a biodiesel compound emulsifier. Background technique [0002] Biodiesel is a renewable and highly safe new fuel. It is based on oil crops such as soybean and rapeseed, oil palm and pistachio and other oil forest fruits, engineering microalgae and other oil aquatic plants, animal fats, and waste cooking oil. etc. as liquid fuels made from raw materials. Biodiesel can be mixed with petrochemical diesel in any ratio, and is a high-quality substitute for petroleum diesel. [0003] However, biodiesel also has its disadvantages, such as biodiesel has high viscosity, poor volatility, high NOx emissions and low calorific value. Microemulsified biodiesel can effectively reduce the viscosity of biodiesel, improve atomization performance, and reduce NOx and soot emissions. [0004] Microemulsion biodiesel is a thermodynamically stable system formed spontaneously from biodiesel, emulsifier (surf...
