Abstract
The present invention relates to process of preparing microemulsified diesel oil. The preparation process includes mixing 0# diesel oil and oleic acid through stirring in water bath for some time to dissolve, dropping water in even rate, dropping ethanolamine via stirring for homogeneous mixing, adding 200# solvent oil after the emulsified liquid become clear, and further stirring for some time toobtain microemulsified diesel oil. The process is simple, and the prepared microemulsified diesel oil is homogeneous, bright, transparent, stable and low in cost.
Description
Technical field
The present invention relates to a kind of preparation method of micro emulsion diesel fuel.
Background technology
Entered since the new millennium, the influence that a lot of in the world countries is globalized has entered the new period of a rapid growth.In this case, the whole world increases day by day to the demand of the energy, and the supply sustainability and the environmental problem of the energy become the problem that the current whole world is paid close attention to most.
Therefore solving an energy starved difficult problem just must " increase income " and " energy-conservation " develops simultaneously in present stage.Though significant effort is made in countries in the world on " increasing income " at present, but it is far from each other with the grand view of oil production in last century, so put forth effort on the work of " energy-conservation " aspect in recent years especially: the one, technically oil engine is improved, raise the efficiency: it two is to improve fuel qualities, improves efficiency of combustion.The additive that adding and its composition are complementary in diesel oil then is a kind of simple and easy to do and effective conservation measures to improve its combustion position.Diesel oil emulsification not only can reduce fuel consumption but also can control discharging as a kind of fuel substitute technology, in fuel-economizing with improve and demonstrated its superiority in the environmental pollution, and is generally paid attention to and explores mutually unexpectedly, and obtain very big development.Though at present a lot of scientific research departments and scientific worker have obtained significant achievement in the field of diesel oil blended with water, the technology of diesel oil blended with water has also developed into quite level, yet diesel oil emulsification does not obtain promotion and application widely so far, and its reason mainly contains:
1, the research of diesel oil emulsification is also not deep fully, and it is also clear fully to form mechanism, does not nowadays yet find complete theory clearly of a cover and standard to estimate the quality good or not of diesel oil emulsification.
2, there is stability problem in diesel oil emulsification itself, and the disperse phase degree of scatter of diesel oil emulsification is inhomogeneous, and phenomenons such as prolonged preservation can be become turbid, bleed, layering influence large-area popularization.
3, in diesel emulsion process in the past, oil and the not stratified purpose of water for the long-term stability that reaches diesel oil emulsification, must add the emulsifying agent of large usage quantity, because the emulsifying agent price is still higher now, a large amount of uses must make the cost of diesel oil improve, and use expensive additive still to need a major issue of paying close attention to so reduce.
4, add the fuel value that other additives improve diesel oil emulsification, further reduce diesel oil and use the environmental pollution problems of bringing also more and more important.
5, all there is the weakness of self in diesel oil emulsification emulsifying combustion mode, can't solve the contradiction that underload stable working and high loading reduce discharging, and moisture flame mechanism is also unclear fully, situations such as ignition difficulties can occur; Influence is promoted the use of on a large scale.
Summary of the invention
Purpose of the present invention: at the problem of present diesel oil emulsification existence, by research to its preparation method, improve diesel oil emulsification emulsifying effectiveness in preparation process, make the particle diameter of diesel oil emulsification be tending towards even, to have a stability higher thereby prepare, combustion efficacy is good, lasting light clarification, the practical micro emulsion diesel fuel that outward appearance is identical with ordinary diesel oil of keeping.
The present invention is achieved through the following technical solutions:
A kind of preparation method of micro emulsion diesel fuel mixes 0# diesel oil with oleic acid, rotating speed with 800～1200 rev/mins in the water-bath about 25～45 ℃ stirred 10～30 minutes, fully dissolving back average rate splashes into water, speed control is 1～3 of per second, dropwising the back keeps 800～1400 rev/mins rotating speed to continue to stir 10～20 minutes, slowly drip thanomin with 1～3 speed of per second again, turn down stirring velocity to 300～800 rev/min, stirring longer for some time makes mixed solution fully emulsified, treats that emulsion becomes limpid back and adds and obtain micro emulsion diesel fuel after the 200# solvent oil stirs for some time.
The invention has the beneficial effects as follows:
The prepared diesel oil emulsification degree of scatter that goes out of this preparation technology is good, the disperse phase particle radius is even, this helps improving " microexplosion " effect and " secondary-atomizing " effect that diesel oil emulsification is produced in combustion processes, makes the diesel oil emulsification burning more complete, reaches the purpose that improves combustion efficacy.
This preparation technology method is simple, is fit to large-scale production application.The practical micro emulsion diesel fuel that adopts this preparation technology to prepare has self layering does not take place, and stability is higher, and the clarification of lasting maintenance light is not stratified, and outward appearance is identical with ordinary diesel oil.And the diesel oil emulsification for preparing has good burning performance, and has the energy saving and pollution alleviation effect.
