Abstract
Diesel oil additives include three additives of No.1 additive with over one kind of non-ionic surfactant, No.2 additive comprising organic acid and inorganic alkali, and the hexadecane value improver. The organic acid in the No.2 additive is cottonseed oil acid, oleic acid or nathphenic acid. The additives are used to compound diesel oil product, and by means of the additives, diesel oil and water are mixed and emulsified. Through replacing diesel oil with the diesel oil product, the present invention makes it possible to save fuel resource.
Description
The present invention relates to a kind of diesel-dope and use the diesel oil goods of this additive.
In recent years, global petroleum resources shortage impels the research of new forms of energy more and more to come into one's own, particularly some developed countries drop into a huge sum of money aspect the new resources research that substitutes natural energy source especially, trial reaches the purpose of obtaining new forms of energy with different technique means, and has all obtained very big progress.But, also just can't apply because involving great expense of some technological method and means causes product to be difficult to satisfy commercial requirement.
In the disclosed technical scheme, can received in actual applications method be mostly emulsion process before the application, its rate of economizing gasoline is about 5～10%, and because the oil in water emulsion stability of producing is bad, storage life is short, and economic benefit is low, so still be difficult to reach the actual popularization stage.
At present, had with water for the emulsion gasoline of gasoline, with the test of the blend gasoline of alcohol gasoline replacing and produce and disclosed record is all arranged, but how to have saved, whether can replace diesel oil still to find no report with water section for this fuel of diesel oil.The applicant in first to file 95104498.2, a kind of composition of catalytic diesel oil catalyst is disclosed, this catalyzer is actual to be a kind of nonionogenic tenside of being made up of by a certain percentage emulsifying agent, ignition dope, suspension agent, lubricant etc., this product application is in diesel oil, all obtaining result preferably aspect fuel-economizing, reduction smoke evacuation and the exhaust emissions, but can only keep about 30 days its butyrous stationary phase usually, though can eliminate the precipitation regeneration that is produced because of long-term placement by mechanical means, bring a lot of inconvenience to use; In addition, these diesel oil goods are actually and are a kind of emulsification shape, and outward appearance feels also bad to the people's.
Purpose of the present invention mainly is to provide a kind of diesel-dope, is made up of three kinds of preparations, and order has used the diesel oil goods of this additive to be the clear shape at normal temperatures, but and long period preservation, and production process is simple, and is with low cost, is suitable for actual applying.
Another object of the present invention is to provide a kind of diesel oil goods that are added with this additive.
Diesel-dope provided by the invention comprises following three kinds of preparations:
(1) No. 1 agent of more than one nonionogenic tenside composition;
(2) No. 2 agent of forming by organic acid and mineral alkali;
(3) cetane number improver;
Wherein, the organic acid of forming No. 2 agent is cotton oil acid, oleic acid or naphthenic acid, and this No. 2 agent comprise by weight: 75～92% cotton oil acid, oleic acid or naphthenic acid;
8～25% mineral alkali.
The nonionogenic tenside and the weight percent thereof of above-mentioned No. 1 agent of the present invention can include:
Sorbitol monooleate: 60～65%
Octadecanoic acid ester of polyethylene glycol: 8～12%
Alkylbenzene oxyethyl group ether: 15～20%
Alkylbenzene gathers ethyl ether: 10～15%
Because tensio-active agent has oleophylic and hydrophilic performance simultaneously, as emulsifying agent, purpose is the emulsification that promotes between the profit.No. 2 agent are made up of mineral alkali and organic acid, and the emulsion clear that its use can help diesel oil and water plays function of stabilizer, and wherein, used mineral alkali does not have special requirement, and preferred mineral alkali includes hydrated barta, calcium hydroxide etc.
Cetane number improver of the present invention can be selected for use and comprise the nitrate compound that contains 1～10 carbon, as cyclohexyl nitrate, isopropyl nitrate, nitric acid n-octyl etc., working is to remedy to mix the reduction that causes cetane value than relatively large water in the diesel oil, guarantees that when improving rate of economizing gasoline combustion efficacy is unaffected.
The preparation method of diesel-dope provided by the invention is very simple, only need No. 1 agent and No. 2 agent are mixed in proportion respectively, packed and got final product, need not special equipment and means, the raw material that uses is the commercialized raw materials on the market, three kinds of preparations can be made the back systems selling by manufacturer, are joined on request by user or next producer and make the diesel oil goods in the diesel oil.
The composition that is added with these diesel oil goods provided by the invention is counted with parts by weight: 50～60 parts of diesel oil, 6～12 parts of 0.05～0.15 part, No. 2 agent of 30～40 parts, No. 1 agent of water and an amount of cetane number improver.The preparation of these diesel oil goods can be according to the following procedure: earlier diesel oil is mixed No. 1 agent of adding afterwards with water, stirred about 2 minutes, make it into white milk sap, then to wherein adding No. 2 agent and stirring 10～20 minutes, chemical reaction and corresponding physics and mechanical change take place rapidly and form transparent water-in-oil combined diesel oil in milk sap meeting this moment, add cetane number improver at last.The usage quantity of this cetane number improver is determined on a case-by-case basis, according to relative national standards, the cetane value of diesel raw material should be not less than 50, cetane value does not reach 50 in the diesel oil of water and in most cases be mixed with, the present invention determines concrete improving agent product and usage quantity thereof according to the size of its gap, belong to the conventional, well-known technology contents about the concrete measuring method of cetane value and the use of improving agent, will not auspicious stating at this.
The diesel oil products appearance that uses additive provided by the invention to make is transparent, with the ordinary diesel oil indifference, analyze after testing, use the parameters index of the diesel oil goods that additive provided by the invention makes and the diesel oil basically identical of international standard, every physical and chemical index comprises:
Flash-point: 58 ℃; Zero pour :-6 ℃; Copper corrosion: 1 grade; Cetane value: 51; Calorific value: 9700 kcal/kg; Kinematic viscosity (20 ℃): 8 centipoises; Sulphur content: 0.02%.
In a word, the purposes of diesel-dope provided by the invention is to make the diesel oil goods, and the mixing and emulsifying by this additive realization diesel oil and water replaces diesel oil to use with these diesel oil goods, reaches the purpose of fuel economy resource.It is engineering machinery, generating set, vehicle and the boats and ships etc. of fuel with diesel oil that the diesel oil goods that the present invention makes can be widely used in all kinds of, engine is had no side effect, and rate of economizing gasoline reaches 15～20%, exhaust smoke level reduces 45%, the exhaust emissions obnoxious flavour reduces 32%, and this diesel oil goods emulsifying effectiveness is stable, but normal temperature is preserved more than 6 months.
The usage quantity of additive provided by the invention in diesel oil seldom, cost own is just very low, but owing to improved rate of economizing gasoline, has also just improved economic benefit, and pollutes from reducing, the angle of protection environment, enforcement of the present invention more can bring considerable social benefit.
