Abstract
The invention discloses microemulsion diesel oil with good thermodynamic stability and belongs to the field of energy chemistry. The formula is characterized by consisting of diesel oil, water and a total assistant, wherein the total assistant is composed of di-mycolic acid fungal acid trehalose, sophorolipid, trehalose glycolipid, lipopolysaccharide complex, lipopeptide, sulfonated betaine, lignin sulfonate, oleic acid, cholamine and amyl nitrate. The microemulsion diesel oil disclosed by the invention is good in thermodynamic stability, good in combustion effect, small in viscosity and free of oil-water stratification phenomenon after long-term storage. Moreover, the microemulsion diesel oil disclosed by the invention can be used for stably improving the vaporization rate of diesel fuel, and the secondary atomization effect of the microemulsion diesel oil ensures more full contact between the diesel fuel and the oxygen, so that the combustion of the diesel fuel is more full; compared with common diesel oil, the oil saving rate of the microemulsion diesel oil disclosed by the invention is larger than 10%, and the tail gas emission is excellent superior than that of national standard diesel oil.
Description
Technical field
The invention belongs to energy chemical field, the present invention relates to a kind of micro emulsion diesel fuel, what be specifically related to is the micro emulsion diesel fuel that a kind of thermodynamic stability is good.
Background technology
In today of energy dilemma, increase income and throttling has become the significant problem in the whole world, the technology of diesel emulsion with it in fuel-economizing and in improving environmental pollution shown superiority out generally paid attention to.But, the poor stability of diesel oil emulsification, the existing problems such as the large and flash-point of viscosity, cetane value, cause not popularized at home.
Summary of the invention
The objective of the invention is: provide that a kind of thermodynamic stability is good, combustion efficacy is good, the little and long time stored micro emulsion diesel fuel that the profit demixing phenomenon also can not occur of viscosity.
For achieving the above object, the technical solution adopted in the present invention is the micro emulsion diesel fuel that a kind of thermodynamic stability is good, the feature of its formula is: by diesel oil, water, total auxiliary agent forms, wherein, total auxiliary agent becomes fat to form by two mycolic acid trehaloses, sophorolipid, marine alga glycolipid, lipopolysaccharides mixture, lipopeptid, sulfonated betaine, sulfonated lignin, oleic acid, thanomin, nitric acid.
The weight percent of its component is:
Diesel oil 72%-87%
Water 10%-25%
Total auxiliary agent 3%
Wherein, each weight percentages of components of the total auxiliary agent of composition is:
The good micro emulsion diesel fuel of a kind of thermodynamic stability of the present invention, its microemulsion particle is less than 0.2 micron, and distributive law is more than 98%.
The present invention compared with the existing technology has the following advantages and positive effect: at first, its size of grains of the diesel oil emulsification of prior art is very large, the viscosity of milk sap is also very large, during use, be unfavorable for atomization and do not reach desirable flash-point and cetane value, thereby, cause the effect of burning to be had a greatly reduced quality; In addition, its emulsion of the diesel oil emulsification of prior art is a kind of thermodynamic unstable system, deposits larger free energy, liquid particle easily bumps and assembles in free movement, after assembling, two are separated, layering, so the diesel oil emulsification of prior art is difficult to store in the middle of daily.Unlike the prior art, its microemulsion of micro emulsion diesel fuel that a kind of thermodynamic stability of the present invention is good and the interfacial tension of diesel oil are very low, it and diesel oil are all without interface, there do not is capillary resistance, has preferably thermodynamic stability, microemulsion in diesel oil can with the diesel oil complete miscibility, they jointly form its combustion efficacy of transparent micro emulsion diesel fuel and package stability better.In the middle of the present invention, the auxiliary and regulating effect of total auxiliary agent approaches its viscosity of micro emulsion diesel fuel, flash-point, cetane value and GB diesel oil that a kind of thermodynamic stability of the present invention is good, more universal the use.
The present invention has more stably promoted the vaporization rate of diesel oil fuel, and the atomizing of its secondary makes fuel more abundant with contacting of oxygen, and then the burning of fuel is also more abundant, more even, has really reached the purpose of energy-conserving and environment-protective.
