Abstract
The invention provides a production process of YDME microemulsion diesel oil. The YDME microemulsion diesel oil is a water-in-oil emulsion which is formed by diesel oil and water in the presence of an emulsifier. The formula of the YDME microemulsion diesel oil (by weight percentages) is as follows: 60-88.5% of the diesel oil, 10-30% of the water, 0.5-1.5% of an oil phase emulsifier, and 1-10% of an aqueous phase emulsifier and an additive. The production process is as follows: adding the oil phase emulsifier to the diesel oil and adding the aqueous phase emulsifier and the additive to the water, respectively stirring, and then adding the water phase mixture to the oil phase mixture for emulsion to obtain a finished product of the microemulsion diesel oil. Compared with other like products, the YDME microemulsion diesel oil has the advantages of stable and excellent performance, greatly reduced toxic gas discharge, long storage life (more than six months), simple production process, low cost, large-scale popularization and application as an oil commodity and the like.
Description
One technical field
The present invention relates to a kind of diesel oil emulsification, specifically be meant a kind of stable performance, storage period is long, and energy-saving and emission-reduction are obvious, micro emulsion diesel fuel easy to use.
Two background technologies
The emulsus ordered mixture that diesel oil emulsification is made up of diesel oil and water.Because it has a clear superiority in energy-conservation and environmental protection than ordinary diesel oil, be subjected to the attention of upper strata, world developed country and some developing countries, as every Western Europe country, the North America, and the states such as Chinese Korea S Japan in Asia since nineteen thirties just relevant research.International fuel association decision in 1981 water blending fuel as one of three big conservation measuress.In China, the exploitations of once dispatching a joint document such as State Scientific and Technological Commission, the Chinese Academy of Sciences, State Planning Commission; Spell out in " saving and the Tenth-Five Year Plan of replacement fuel " that State Economic and Trade Commission puts into effect and " give priority to fuel-saving techniques such as fuel emulsification, fuel oil additive.”
Diesel oil emulsification is not " water becomes oil ", and it is the diesel oil based on about 70%, adds by about 30% water, about 1% emulsifying agent, becomes a kind of " water-in-oil " type environment-friendly energy-saving diesel fuel through high-strength emulsification pretreatment.It possesses six big effects:
The one, cracking energization effect, water is made up of hydrogen and oxygen, can cracking go out the hydrogen participation burning higher 3.52 times than diesel oil energy under the High Temperature High Pressure; The 2nd, the confession oxygen effect, cracked oxygen makes burning more abundant for burning has increased comburant oxygen; The 3rd, effect of micro-explosion when producing the steam than self big 1700 times of volume during water vapor, can be broken through oil film oil is atomized once again, thus more abundant burning; The 4th, water coal vapour effect, water vapor heat releases a large amount of with failing that incendiary CO is converted into CO2; The 5th, equal heat effect, steam can reduce cylinder body localized hyperthermia effectively and protect body, the resistance of reducing friction, alleviate coking; The 6th, environmental protection effect, emulsifying combustion can reduce the flue gas blowdown flow rate more than 30%.As seen, emulsifying combustion has reliable science.More valuable is the water and the synthetic ignition dope of adding 30% in diesel oil, means to have substituted 30% oil fuel in today of energy dilemma, to have huge energy-saving significance.
At present, the diesel oil emulsification of China is having certain effect aspect energy-conservation and the minimizing environmental pollution, but exists following problem in production application:
(1) preservation period is short.General preservation period is 1-3 month, and this is because the effect of molecular thermodynamics motion makes droplet be condensed into large water drop separates out from oil, can't use, therefore can not have enough to meet the need as tank oil, can only be supporting self-produced personal with oily unit, bring limitation to popularization.Because preservation period is short, cohesion thickening phenomenon often occurs simultaneously, the oil nozzle latch up phenomenon takes place, also make troubles to application.
(2) emulsifying device costliness.Present most ultrasonic emulsification equipment that adopt of emulsifying device, have in addition use super magnetic to add ultrasonic emulsification, equipment scale is big, and payback period is long and complicated, in case damage is difficult to keep in repair.
(3) outward appearance is an oyster white.Oil in water emulsion majority of various countries' development at present be oyster white, all belongs to the milk sap carburetion of phase III, and when popularization, the user is difficult to accept this oyster white, and wishes that outward appearance answers similar ordinary diesel oil, clear.
(5) discharged nitrous oxides does not also solve.
(6) add water 20% when above, cetane value has obvious reduction.
Thereby the popularity that has influenced diesel oil emulsification is applied.Therefore if will make diesel oil emulsification obtain popularizing in an all-round way, be necessary reducing discharged nitrous oxides, improve aspects such as fuel value and stationary phase and do deep research, develop a kind of better emulsifying technology as tank oil.
Three summary of the invention
Technical problem to be solved by this invention provides a kind of preparation method of novel emulsion diesel oil.This novel emulsion diesel oil is a kind of " water-in-oil-type " micro emulsion diesel fuel.Its prescription (weight %) is: diesel oil 60-90%, water 10-30%, oil phase emulsifier 0.5-1.5%, aqueous emulsifier phase and auxiliary agent 1-10%.
Wherein oil phase emulsifier is made up of sorbester p17 (0.45-1.35%) and tween 80/60 (0.05-0.15%).Aqueous emulsifier phase and auxiliary agent are by oleic acid (1.5-8.5%), sodium hydroxid or ammoniacal liquor (0.15-0.85%), polyvinyl alcohol (0.055-0.075%), soybean lecithin (0.1-0.5%), urea (0.1-0.5%), petroleum sodium sulfonate (0.1-0.15%), 2-EHN (0.5-1.5%), trolamine (0.3-1%) is formed.
The production technique of micro emulsion diesel fuel: oil phase emulsifier is added diesel oil, aqueous emulsifier phase and auxiliary agent are added in the entry, stir respectively, water is joined in the oil phase mix then through static mixer, and then through high-shear emulsion machine emulsification, micro emulsion diesel fuel gets product.
Micro emulsion diesel fuel can be widely used in oil engine, Industrial Stoves and boiler.
Compare with existing similar technology, it has following advantage the present invention:
1. emulsifying process can carry out under 20-50oC, and production safety is reliable.
2. the micro emulsion diesel fuel water is uniformly dispersed, and size of particles is at micron order, because function of stabilizer, milk sap is stable, and self is not stratified, and be 6-12 month storage period.
3. outward appearance is near diesel oil, and is limpid transparent, haze-free, and (the sort of oyster white that is difficult past oil in water emulsion fully), the user easily accepts.
4. owing to the effect of 2-EHN, the efficiency of combustion of micro emulsion diesel fuel improves greatly, and cetane value is that the 90-96%. oil product startability of diesel oil is good, and horsepower is big, is suitable for all vehicle load operations.
5. fine preservative property: power-equipment is not produced corrosion.
6. more than the energy-conservation 10-20%, tail gas reduces discharging 30-70%, particularly oxynitride and reduces discharging greater than 70%.
