Abstract
An emulsified diesel oil suitable for the winter contains the fuel oil including diesel oil (40-70 wt.%), water (15-30), emulsifier (15-30). Said emulsifier is composed of the nephthenic acid or the mixture of nephthenic acid and oleic acid (80-90 wt.%) and the industrial ammonia water or the mixture of industrial ammonia water and ethanolamine (10-20). Its advantages are not layering, high transparency, high caloric power and high start speed.
Description
Technical field
The present invention relates to diesel oil emulsification.
Background technology
Diesel oil emulsification is to add water in the diesel oil to mix by emulsifying agent etc. and form.International fuel association decision in 1981 water blending fuel as one of three big conservation measuress.The diesel oil emulsification of water mixing is an emulsified water-in-oil diesel oil, possesses six big effects: the one, and cracking energization effect: water is made up of hydrogen and oxygen, can cracking go out the hydrogen participation burning higher 3.5 times than diesel oil energy under the High Temperature High Pressure; The 2nd, the confession oxygen effect: cracked oxygen has increased more comburant oxygen for burning; The 3rd, effect of micro-explosion: when producing the steam than self big 1700 times of volume during water vapor, can break through oil oil is atomized once again, thus more abundant burning; The 4th, water-gas effect: water vapor heat releases a large amount of with failing that the incendiary carbon monoxide is converted into carbonic acid gas; The 5th, equal heat effect: aqueous vapor can effectively reduce cylinder localized hyperthermia and protect body, and the resistance of reducing friction alleviates coking; The 6th, environmental protection and energy saving effect: water has replaced part of fuel oil, thereby has huge energy-conservation and environment protection significance, has made positive contribution for saving petroleum resources.
The performance of diesel oil emulsification is mainly decided by emulsifying agent, is made up of multiple diesel oil emulsification and emulsifying agent in the prior art, cut both ways, by form and complex process, the transparency that has is poor, storage time of having is short etc.
Summary of the invention
Technical problem to be solved by this invention provides and is fit to the diesel oil emulsification that uses winter, and through emulsifying agent emulsive diesel oil limpid transparent and the same color of diesel oil, standing storage never degenerates, not stratified, the calorific value height.
Emulsified diesel oil for winter use of the present invention, comprise diesel oil, water, emulsifying agent, it is characterized in that by weight percentage, the oil fuel that comprises diesel oil by 40～70%, 15～30% water, 15～30% emulsifying agent are formed, described emulsifying agent is made up of 80～90% naphthenic acid or the industrial ammonia of naphthenic acid and oleic mixture and 10～20% or the mixture of industrial ammonia and thanomin by weight percentage, and industrial ammonia is 17～23% in ammonia quantity.
Emulsifier component provided by the present invention is few, mainly is made up of naphthenic acid and ammoniacal liquor, converts the weight that ammonia quantity calculates other concentration ammoniacal liquor for the ammoniacal liquor of other concentration according to the ammoniacal liquor of above-mentioned concentration.Ammoniacal liquor also can partly be replaced by thanomin, and the amount of thanomin substitutes half ammoniacal liquor at most, and is preferred about 1/3, and the maximum consumption that also is thanomin is 5～10%.
For naphthenic acid, also can partly replace by oleic acid, oleic amount is 0～15%, preferred 8～15%.
Because winter temperature is low, in order to reduce the zero pour of diesel oil, should add kerosene in the diesel oil emulsification, simultaneously can be by methyl alcohol instead of part diesel oil in order to reduce cost.But when methyl alcohol adds 35% to, can not need to add again kerosene.Diesel oil, kerosene, methyl alcohol are referred to as oil fuel, described 40～70% the oil fuel that comprises diesel oil is made up of 0～35% methyl alcohol, 0～30% kerosene and the diesel oil of surplus, wherein methyl alcohol and kerosene can not be zero simultaneously, and quantity of methyl alcohol can not be zero in the amount of 35% kerosene when following.Diesel oil can be the diesel oil of various labels.
Relatively more suitable consists of:
Diesel oil by 10～60%, 15～30% water, 15～30% emulsifying agent, 10～30% kerosene are formed, and wherein the total amount of diesel oil and kerosene is 40～70%.
Diesel oil by 10～35%, 5～35% methyl alcohol, 15～30% water, 15～30% emulsifying agent, 0～30% kerosene are formed.When methyl alcohol adds 35% to, can not need to add again kerosene.The total amount of diesel oil, methyl alcohol and kerosene is 40～70%.
The manufacture craft of emulsifying agent is one in high-speed shearing machine naphthenic acid and ammoniacal liquor high speed shear being made it to dissolve each other.
The preparation of diesel oil emulsification is emulsifying agent to be added to add water in the oil fuel and mix and get final product.
Advantage of the present invention:
Emulsifier component is few, and preparation technology is simple, and is limpid transparent with its emulsive diesel oil, with the same color of diesel oil; Standing storage is not stratified, never degenerates; The calorific value height, horsepower is big, starts fast.Diesel oil emulsification oyster white, opaque, appearance poor, contaminated product layering and precipitating, short defective of storage time have thoroughly been overcome in the past.After tested, the flash-point of diesel oil emulsification is 55 ℃, and calorific value is 9000 kilocalories.
