Problems solved by technology

These formulas can solve the methanol-diesel miscibility problem to a certain extent, but there are still problems such as easy layering, insufficient mutual solubility and clarity, or low cost performance.
[0009] Most of the biodiesel currently on the market is formed by adding a combustion enhancer to the main body of methyl oleate, which has the defects of high freezing point, high cold filter point, strong corrosion and insufficient cost performance, and there is an urgent need for an improved Its combustion performance, especially its compression ignition performance, is an additive to improve its comprehensive cost performance

Abstract

The invention provides a multiple-component combined diesel oil additive and its preparing method, the diesel oil additive includes, on the basis of 100 parts by weight, 5 to 78 parts by weight of oleic acid; 5 to 88 parts by weight of methanol or ethanol or a mixture thereof; 1 to 31 parts by weight of a surface active agent; 1 to 42 parts by weight of a modified additive and 0 to 73 parts by weight of industrial water which is added according to the concrete application. New a multiple-component biodiesel can be obtained by adding of the additive into conventional fossil diesel, a methanol modified complex or their mixture, and the biodiesel has the advantages of high cetane number, high flash point, low condensation point, low cold filter plugging point, low corrosion, low emission and low cost.

Description

technical field [0001] The invention relates to the field of fuel oil, in particular to a diesel additive using multiple formulation combinations and a preparation method thereof. Background technique [0002] my country is short of oil and gas, relatively rich in coal resources, and has a wide source of coal-based alcohol ether fuels. Substituting superior alcohol ether resources for petroleum resources, or using alcohol ether fuels and petroleum mixtures to replace petroleum resources, is beneficial to the ecological environment and promotes economic growth. Sustainable development, and can create new economic growth points. [0003] Many countries have promoted ethanol gasoline. The amount of ethanol added to petrochemical gasoline is generally 10-15%. However, since ethanol is mainly derived from crops, its promotion faces many problems such as cost and food safety. Therefore, in recent years, it has focused on promoting the addition of methanol. The main source of metha...
