Problems solved by technology

[0005] Some of the additives in ethanol and diesel disclosed in the above technologies cannot solve the high proportion of ethanol blending ratio or cannot guarantee the long-term stability of ethanol-diesel. The cost
Moreover, the mixed fuels of ethanol and diesel mostly go through cumbersome processes such as high-speed shearing and stirring, magnetization, etc., so that the economical efficiency of existing ethanol diesel is relatively poor, which is not conducive to popularization and application

Abstract

The invention relates to an ethanol-diesel compound additive and a preparation method thereof, belonging to the field of additives of petroleum products. The invention provides an ethanol-diesel compound additive, wherein the ethanol-diesel compound additive is composed of a surfactant, a cosolvent, a metal corrosion inhibitor, a hexadecane value improver and a lubrication additive. The additive provided by the invention has the advantages that the content of ethanol can be increased, the phase separation resistant performance is good, the bright and clear properties of the additive can be kept permanently, the resistance to corrosion and the oil-saving effect are good, the discharge of harmful gas within the vehicle exhaust is reduced effectively, the additive can be directly used without transforming the existing diesel motor and the economic benefits and the social benefits of the additive are significant.

Description

technical field [0001] The invention belongs to the field of petroleum product additives, in particular to an ethanol diesel compound additive and a preparation method thereof. Background technique [0002] Diesel consumption in my country is relatively large, and the harmful emissions of diesel engine nitrogen oxides (NO x ) and soot particles (PM) have become the main sources of urban air pollution. After testing and application, it is found that as long as a small amount of ethanol fuel is blended with diesel oil, the sulfide, black smoke, particulate matter and NO of the diesel engine can be significantly reduced. x and other harmful substances, and can also save fuel, which has better environmental protection and economic benefits. In addition, the limited oil reserves and production are difficult to meet the growing demand of the society. my country has become a major oil importer. Substituting part of diesel with ethanol is also conducive to ensuring my country's en...
