Problems solved by technology
[0005] However, in order to meet the standard requirements of biodiesel (fatty acid monoester, not mixed with petrochemical diesel), it is necessary to reduce the moisture content to less than 0.5%, the drying process is complicated, and the energy consumption is large, which further aggravates the cost burden and brings difficulties to commercialization. many difficulties

Abstract
The invention relates to biological diesel oil with high water content and its application. It belongs to liquid fuel technical field. The constituent weight percentages of the biological diesel oil are follows: fatty acid monoester 75-98%, water 1-20%, and emulsifier 0.1-5% whose hydrophilic oleophilic equilibrium value HLB is 1.0-8.0. And its features at room temperature are that its density is 0.80-0.96g / cm3; viscosity is 1.0-10.0 mm2 / s; heat value is 32.00-42.00MJ / Kg; solution surface tension is 1.0*10-2-8.0*10-2N / m; and dripping diameter is 0.001-10.00um. The invention offers the emulsifying biological diesel oil with high water content which has storage stability. And it can simplify removing water technology, reduce manufacturing cost, and improve the burning performance of the biological diesel oil.
Description
technical field [0001] The invention relates to biodiesel with higher water content and its application. It belongs to the technical field of liquid fuel. Background technique [0002] Biodiesel (Biodiesel), also known as fatty acid monoester (Fatty Acid Ester), is made from vegetable oil or animal fat oil, waste cooking oil, etc., and undergoes transesterification reaction with alcohols (methanol, ethanol) get. The combustion value is close to that of petrochemical diesel, and the cetane number is higher than that of petrochemical diesel. It is a renewable green fuel that can be fully burned and can be used as a substitute for petrochemical diesel. Or mixed with petrochemical diesel. [0003] The main component of biodiesel is fatty acid monoester (mainly methyl ester and ethyl ester), which is a renewable green fuel. Compared with petrochemical diesel, the characteristics of biodiesel are: 1. It has excellent environmental protection characteristics. Biodiesel has a l...
