Abstract
The invention discloses a micro-emulsified methanol diesel fuel, and belongs to the energy chemistry field. The formula of the micro-emulsified methanol diesel fuel comprises diesel oil, methanol and total assistants, wherein the total assistants comprise sodium petroleum sulfonate, Span60, polyoxyethylene octylphenol ether, isobutanol, isoamyl alcohol, isopropyl ester, triisobutyl phosphate and glyceryl monooleate. The micro-emulsified methanol diesel fuel has the advantages of good corrosive resistance, stable thermodynamic system, high calorific value, low micro-emulsification cost and realization of a fuel saving rate of 10-25%, and a stripping effect generated during the combustion of the micro-emulsified methanol diesel fuel carries off a large amount of harmful substances comprising CO, NOx and the like, so the energy saving and environmental protection purposes are realized. The micro-emulsified methanol diesel fuel has an obvious economic benefit and can be widely popularized and applied to engines of automobiles.
Description
Technical field
The invention belongs to energy chemical field, the present invention relates to a kind of methanol diesel-oil, be specifically related to a kind of methanol diesel-oil of microemulsified state.Be mainly used in for automobile.
Background technology
Diesel oil is one of bulk product of refining of petroleum, is widely used as diesel vehicle, the fuel of beeliner, boats and ships and massive engine blocks etc.The diesel oil kind that China produces is at present divided into solar oil, heavy gas oil and special-purpose diesel oil, and wherein solar oil accounts for 98% of ultimate production.Diesel oil is mixed the method configuration that alcohol fuel generally adopts emulsification.The history of emulsion fuel is longer: occur the forties in 20th century; Start methanol diesel-oil to carry out broad research the eighties in 20th century, and research shows that methanol diesel-oil increases engine thermal efficiency, meanwhile, has reduced the discharge of particulate, but also cause, power declines and the problem of cylinder sleeve corrosion; In addition, the poor stability of methanol diesel-oil is difficult for the problem storing; Seriously limited the universal of methanol diesel-oil.
Summary of the invention
The object of the invention is: provide that a kind of erosion resistance is good, thermodynamic system is stable, calorific value cost high, microemulsified is low, be easy to the microemulsified state methanol diesel-oil of extensively universal and energy-conserving and environment-protective.
To achieve these goals, the technical solution adopted in the present invention is a kind of methanol diesel-oil of microemulsified state, the feature of its formula is: diesel oil, methyl alcohol, total auxiliary agent, consist of, wherein, total auxiliary agent is comprised of sorbester p18, petroleum sodium sulfonate, polyoxyethylene octylphenol ether, isopropylcarbinol, primary isoamyl alcohol, isopropyl ester, three iso-butyl ester of phosphoric acid, glyceryl monooleate.
The weight percent of its component is:
Diesel oil 80%---94%
Methyl alcohol 5%---18%
Total auxiliary agent 1%---2%
Wherein, each weight percentages of components that forms total auxiliary agent is:
The methanol diesel-oil of a kind of microemulsified state 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: first, the methanol diesel-oil of prior art, when application, its power sending is undesirable, also makes engine interior occur the problem of corrosion, and, its thermodynamic system is unstable, and easily layering is difficult for storing.Unlike the prior art, its manufacturing process of methanol diesel-oil of a kind of microemulsified state of the present invention is simple, emulsifying device less demanding, thermodynamic system is stablized (microemulsion particle is less than 0.2 micron), store 2 years also not stratified above, to not corrosion and wearing and tearing of engine, can also play sanitising agent, can reduce the maintenance cost of engine.Total auxiliary agent of the present invention, the per-cent consumption that accounts in the present invention total liquid is little, is generally no more than 2%, wherein, adopted petroleum sodium sulfonate, it is good emulsifying agent, is again anticorrosive rust-preventive agent preferably, in addition, having adopted three iso-butyl ester of phosphoric acid is combustion efficacy improving agent etc., rate of economizing gasoline of the present invention is 10%～25%, and economic benefit of the present invention is obvious, and extensively popularization and application is used to the engine of automobile.
In addition, the methanol diesel-oil of a kind of microemulsified state of the present invention, during burning, the effect of its secondary-atomizing makes fuel (methanol diesel-oil) contact more abundant with oxygen, promote fuel (methanol diesel-oil) more fully to burn, during its burning, can produce stripping effect, taken away the objectionable impuritiess such as a large amount of CO, NOx, thereby, reach the object of energy-conserving and environment-protective.
