Abstract
An emulsifier composition contains dewatered sorbitol oleate (5-15 wt.%), dewatered sorbitol oleate polyoxyvinethene (50-60), alkylphenol polyoxyvinethene (5-8), lactate (4-8), cetane number improver (5-10), polyol amine (5-8), sulfonate (4-7), organomagnesium salt (2-4), naphthenate (5-9) and organoiron salt (2-4). It is used to prepare emulsified diesel oil from water and diesel oil.
Description
The present invention relates to the oil plant emulsifier composition, and relate to the diesel oil emulsification that makes with this emulsifier composition.Specifically, the present invention relates to the diesel oil emulsifier composition, and the diesel oil emulsification that makes with this diesel oil emulsifier.
In national economy, various oil plants (as heavy oil and diesel oil) have obtained using widely as the main energy.Along with to the increase of oil plant demand with to the pay attention to day by day of environment protection, also more and more higher to the requirement of oil plant, one of them requires oil plant fully to burn exactly, thereby can not only be energy-conservation, and can also reduce the flammable objectionable constituent in the tail gas.
Proposed already manyly can make the clean-burning method of oil plant, one of them adds entry exactly in oil plant and emulsifying agent makes oil plant emulsification, thereby reduces the diameter of oil plant drop, increases the contact area with oxygen, reaches clean-burning purpose.
Fan Qilian etc. disclose a kind of method of using mixed surfactant to prepare diesel fuel-water microemulsion in that " chemical engineer " 1997 the 5th is interim.It uses by nonionogenic tenside (NP
4+ NP
7) and the mixed alkoxide solution of anion surfactant calcium dodecylbenzene sulphonate as mixed surfactant, to make emulsifier content be 5.9 weight %, water content 14.9 weight % and place and still clarify not muddy oil in water emulsion half a year.
Though this emulsifying agent can make the oil in water emulsion with gratifying stability, also there is the defective that additive amount is big, water content is low in it, thereby increases the cost of oil in water emulsion, makes oil in water emulsion be difficult to burn more fully.
Therefore, need the high emulsifying agent of a kind of water capacity of exploitation, only need a small amount of described emulsifying agent just can make to have the combustion heat value height, the stability diesel oil emulsification of advantage by force.
The purpose of this invention is to provide a kind of emulsifier composition, the water capacity height of described emulsifier composition only needs a small amount of described kind of emulsifier composition just can make to have the combustion heat value height, the stability diesel oil emulsification of advantage by force.
Another object of the present invention provides the diesel oil emulsification that the described emulsifier composition of a kind of usefulness makes.
The invention provides a kind of emulsifier composition, it comprises 5-15 weight % Span-80,50-60 weight % Span-80 Soxylat A 25-7,5-8 weight % alkylphenol polyoxyethylene, 4-8 weight % lactate, 5-10 weight % cetane number improver, 5-8 weight % polyhydric alcohol amine, 4-7 weight % sulfonate, the organic magnesium salts of 2-4 weight %, 5-9 weight % naphthenate and the organic molysite of 2-4 weight %.
The example that is used for the alkylphenol polyoxyethylene of emulsifier composition of the present invention has polyoxyethylene octylphenol ether and polyoxyethylene nonylphenol ether, wherein better is polyoxyethylene nonylphenol ether.Its content in composition generally accounts for the 5-8% of composition total weight.
In emulsifier composition of the present invention, can contain the lactate that accounts for described composition total weight 4-8%, be used to accelerate the ignition rate and the combustionvelocity of diesel oil.The example of this lactate comprises methyl lactate, ethyl lactate and n-Butyl lactate etc.Wherein be preferably n-Butyl lactate.
The purpose that adds cetane number improver in the present composition is in order to improve diesel-fuel cetane number, to improve the combustioncharacteristics of diesel oil, reduce the noise of diesel engine, improving the cold startability and the stable working of diesel engine.Described hexadecyl improving agent can be nitric ether such as ethyl nitrate, amyl nitrate, isoamyl nitrate, the own ester of nitric acid, isooctyl ester nitrate; Nitrous acid ester; Aldehyde; Ether; Compounds such as oxime.Better be nitric ether, preferably isooctyl ester nitrate.Its content accounts for the 5-10% of described emulsifier composition gross weight.
The consumption of polyhydric alcohol amine generally accounts for the 5-8% of composition total weight in the present composition.Its effect mainly is as stablizer.The example of described organic amine is by diethanolamine and trolamine etc.
In emulsifier composition of the present invention, the content of described sulfonate accounts for the 4-7 weight % of composition total weight.Its effect mainly is the combustion-supporting cigarette that falls.The example of described sulfonate has oil alkylsulphonic acid calcium and oil barium alkylsulfonate etc.Oil alkylsulphonic acid calcium preferably.
In the present composition, also can contain organic magnesium salts that 2-4 weight % is used to suppress to generate oxynitride and flue dust.The example of described organic magnesium salts has oil-soluble magnesium salts such as magnesium naphthenate, Magnesium Stearate.
In the present composition, also contain and account for composition total weight 5-9 weight % naphthenate.The example of described naphthenate comprises the naphthenate of transition metals such as copper, manganese, cobalt, nickel, zinc.Can be used singly or in combination described carboxylate salt.In the present composition, the effect of naphthenate mainly is as ignition dope, and it is more complete that fuel combustion is got, and suppresses the generation of oxynitride, hydrocarbon, carbon monoxide and flue dust, reduces topsoil.
In the present composition, also contain the organic molysite that accounts for composition total weight 2-4%.The example of this organic molysite comprises oil soluble molysite such as iron naphthenate, ferrocene, and it mainly acts on is to reduce the amount of flue dust and the unburn amount of carbon completely, can suppress the generation of hydrocarbon, carbon monoxide and oxynitride simultaneously.
Be 1 weight % at emulsifier content, when water content is 15 weight %, use the low heat value of the diesel oil emulsification that emulsifier composition of the present invention makes to reach 7612kcal/kg, and can reach 30 days not stratified stationary phase, is much better than the diesel oil emulsification that makes with existing emulsifying agent.
