Description
Technical field
The present invention relates to a kind of novel clean fuel, particularly, a kind of ether fuel of cleaning.This ether fuel comprises dme, methyl alcohol and succimide.More specifically, this ether fuel can only be made up of dme, methyl alcohol and succimide.The invention still further relates to the propellant combination that comprises ether fuel of the present invention and gasoline.
Background technology
As everyone knows, oil is as a kind of non-renewable resource, plays a part indispensable in the social life of a country and national defense construction.Along with improving constantly of China's living standards of the people, automobile has progressed into common people's family.For example, Beijing has just entered the epoch of 4,000,000 automobiles now.Therefore, along with the increase of automobile pollution, the needs of gasoline are also being increased day by day.The crude production rate of China can not satisfy the flourish needs of domestic economy far away.Now, China becomes crude oil net importer from crude exports state, and most of crude oil of China is dependence on import all.The aggravation of this situation will seriously restrict further developing of China's economy, even can have influence on the national defense safety of China.Therefore, need find a kind ofly to need not to use petroleum, thereby also just need not vehicle fuel from external Imported oil.
In addition, along with popularizing of automobile, a large amount of exhaust emissionss make automobile bringing people's life simultaneously easily in atmospheric environment, also bring people's various diseases, particularly respiratory tract disease.In recent years, motor vehicle exhaust becomes the people's attention focus.In order to reduce the variety of issue that motor vehicle exhaust brings, countries in the world have proposed strict requirement to vehicle exhaust, comprise that there is related request in the U.S., and there is Europe IV standard in Europe, Japan has carried out allegedly the strictest standard, and China also is equivalent to the standard of Europe III or Europe IV in implementation.And each country will be strict further for the requirement of exhaust emissions.For example, each state formulation exhaust emission standard stricter than American National Standard separately agreed by the U.S..State IV standards has been carried out in advance at the eve that hosts the Olympic Games in Beijing, and will carry out state V standard as early as possible.Therefore, need a kind of clean fuel that can substitute present employed motor spirit, this fuel is when satisfying the function of motor spirit, and exhaust emissions is clean environment firendly more.
Benzene is the carcinogens of generally acknowledging, it because evaporation and burning, exhaust emissions enter atmosphere, brings direct influence to human beings'health in gasoline.Therefore, all this index is limited in European Union, Britain, Australia and the Russian gasoline standard, general provision is for being not more than 5% (v/v).According to Beijing's provincial standard, require the content of benzene to be not more than 1.0 volume %.But as environmental requirement, national governments and appropriate authority also may propose stricter restriction.
Aromatic hydrocarbons is a kind of gasoline blender with higher octane and high heating value.But can cause the formation of carcinogens benzene after its burning, and easily increase the carbon deposit of combustion chamber and increase CO
2Discharging.It is generally acknowledged that the content of benzene and other aromatic hydrocarbons is big more in the gasoline, then the benzene content in the products of combustion is big more.Therefore, aromaticity content will help environment because of the discharging that reduces benzene in the tail gas in the reduction gasoline.
China is a big coal country, and coal reserves is very abundant.With the abundant in coal resource conversion is that oil fuel is a research direction always.With coal conversion is that methyl alcohol, dme also are the important directions of present coal utilization.Units such as Shaanxi New-type fuel burner company have worked out ether-base gasoline additive, this additive comprises the dme of 5-37%, the low-carbon alcohol compounds of 10-60%, the C5-10 hydrocarbon compound of 10-50%, the alkylphenol of 0.1-5% is to the alkylphenol of Soxylat A 25-7 and 0.05-0.5%.This additive is mixed with gasoline, can produce ether-base composite gasoline.Chinese invention patent application CN98112948.X has also disclosed a kind of ether-base gasoline additive, and it is made up of following component: 15.5% dme, 42% methyl alcohol, 39% benzene, 3.3% alkylphenol polyoxyethylene and 0.2%2,6-ditertbutylparacresol.Influenced by this, the annual production of China's dme can reach millions of tons at present.Yet above-mentioned two kinds of ether-base gasoline additives are because the production cost height, and all contain a large amount of benzene, make the gasoline that is added with these two kinds of ether-base gasoline additives will can't satisfy in the existing gasoline standard requirement to benzene content at all.And, think that in gasoline adding benzene will inevitably cause also that benzene content sharply raises in the gasoline combustion product, thereby environment and human body are damaged.Now, numerous dme manufacturer is in limited production owing to the product marketing problem or stops production, and waits for the difficult condition of looking around.
Therefore, if can use dme to produce clean fuel, not only do not worry raw material sources, and can solve the present problem of these producers.
Though the standard of methanol gasoline is is now issued and implemented, because still there are some problems in the substance characteristics of methyl alcohol: the one, methyl alcohol engine cold-start difficulty, burning poor with respect to the volatility of gasolene ingredient, that cause the use methanol gasoline is insufficient; The 2nd, the mutual solubility of methyl alcohol and gasoline is poor, and the quality guaranteed period is short, layering apt to deteriorate; The 3rd, substitute than low (promptly needing to use about 1.6-1.7 part methyl alcohol to substitute 1 part gasoline), the 4th, if do not change engine structure, methanol gasoline burns insufficient in available engine, the dynamic property deficiency.
Mainly comprise following several at the employed additive of oil products such as gasoline and diesel oil: 1) octane promoter, the combustioncharacteristics that it is used to improve gasoline improves its octane value; 2) antioxidant, it is used to improve the gasoline that contains the secondary processing component and the oxidation stability of diesel oil; 3) frostproofer is used for preventing that the rocket engine fuel micro-moisture from freezing at low temperatures, causes influencing the engine works better because of the oil transportation difficulty; 4) static inhibitor is used to improve the specific conductivity of oil products such as rocket engine fuel, prevents to cause fire because of triboelectrification when high-speed pump is carried and filter; With 5) fluidity improver, be used for changing the crystal form of diesel oil paraffin, improving the flowability of oil product when the low temperature, or the like.
Purification agent has been a kind of lubricated oil additives that is mainly used in fastest developing speed since the sixties in 20th century, and it can suppress machine oil and produce greasy filth when the crankcase working temperature is low, thereby avoids that oil circuit stops up, parts corrosion and wearing and tearing.In the purification agent most widely used general, usage quantity is maximum is succimide type purification agent, it comprises the polyolefinic succinimide imide of succimide, polyolefinic succinimide imide, boronation and N-halogenated succinimide imide etc.
At present, the industrial thermal stability polyolefinic succinimide imide replacement preferably succimides that adopt more, this is because the high-temperature stability of succimide is not enough.And succimide also mainly makes an addition to lubricating oil as purification agent, in the machine oil as oil engine, does not see it is made an addition to report in the ether fuel.

The present inventor is through a large amount of test and screening, finds to use the New-type fuel that comprises dme, methyl alcohol and succimide to solve or part overcomes the problems referred to above of this area unexpectedly.
A first aspect of the present invention
A first aspect of the present invention relates to a kind of novel ether fuel, and this novel ether fuel is based on the fuel of dme.Particularly, this novel ether fuel comprises dme, methyl alcohol and succimide.
Novel ether fuel of the present invention does not use petroleum resources, and the gasoline that can replace deriving from oil fully acts as a fuel and is used for automotive industry.Up to now, can't reckon with that from prior art comprising dme and methyl alcohol can be used as fuel as the composition of main ingredient and use, particularly can be used as vehicle fuel and make and be used for gasoline replacing.Can't reckon with at all that from prior art the ether fuel of being made up of dme and methyl alcohol can replace gasoline commonly used to be used for the fuel of automobile fuel or other vehicles and power-equipment fully.Up to now, can't reckon with more that from prior art the composition that comprises dme, methyl alcohol and succimide can be used as fuel and uses, particularly can be used as vehicle fuel and make and be used for gasoline replacing.Can't reckon with at all that from prior art the ether fuel of being made up of dme, methyl alcohol and succimide can replace gasoline commonly used to be used for the fuel of automobile fuel or other vehicles or power-equipment fully.
Gasoline is the mixture of C4-C10 alkane normally, and contains materials such as benzene and toluene.
Ether fuel of the present invention does not contain the gasoline main ingredient, and ether fuel promptly of the present invention does not contain the above hydrocarbon of C4, C4-C10 alkane for example, benzene or the like.In this article, " do not contain the above hydrocarbon of C4 " and be meant and do not have a mind to add the above hydrocarbon of C4.
Ether fuel of the present invention mainly comprises dme, methyl alcohol and succimide.Generally speaking, in ether fuel of the present invention, be 100 weight parts in the gross weight of dme and methyl alcohol, the content of dme can be the 4-12 weight part, and the content of methyl alcohol can be the 0.005-0.02 weight part for the content of 88-96 weight part and succimide.Preferably, in this ether fuel, be 100 weight parts in the gross weight of dme and methyl alcohol, the content of dme is the 5-9 weight part, the content of methyl alcohol is that the content of 91-95 weight part and succimide is the 0.008-0.012 weight part.
Below these three kinds of components are described in detail.
Dme is a kind of colourless, tasteless and nontoxic compound.Dme is gas under normal temperature and normal pressure.Its molecular weight is 46, and oxygen level is 35, and air-fuel ratio is 9, and empty combustion heat vale of mixture is higher than diesel oil (3067/2911), and cetane value is 60 (than the high 5-12 of a diesel oil unit), and CO and HC hang down 55% and 86% respectively than gasoline in the exhaust emissions.Therefore, the ratio of combustion gasoline of dme is more complete, and products of combustion is than more environmental protection of gasoline.The combustionproperty of dme and good mechanical property, explosive power is strong, and these performances all are better than methyl tertiary butyl ether.
The molecular weight of methyl alcohol is 32, and oxygen level is 50%, and air-fuel ratio is 6.4 (gasoline is 14.8), and octane value is 112 (than the high 15-22 of a gasoline unit), and empty combustion heat vale of mixture is lower than gasoline (2656/2786) slightly, and pollutant effulent is better than gasoline.The wide material sources of methyl alcohol more can directly be prepared by coal, and cost is lower.
Dme used in the present invention and methyl alcohol can be the twice-laid stuff of the discarded recycle of fertilizer plant from coal-based Poly-generation, wide material sources, and with low cost.
The molecular formula of succimide (CAS:123-56-8) is C
4H
5NO
2, molecular weight is 99.09, also is called succinimide, 2,5-pyrroline diketone, succsinic acid imide etc., and its structural formula is as follows:
Its product is generally colourless needle crystal or has filbert glossy thin slice.Fusing point is 123-127 ℃, and boiling point is 285-290 ℃ (easily decomposing), and flash-point is 201 ℃, and relative density is 1.412 (16 ℃).Soluble in water, alcohol or sodium hydroxide solution are insoluble to ether and chloroform etc.It is sweet to distinguish the flavor of.
Succimide used in the present invention can be the business-like product of producing by any technology (as chlorination, hot adduction).
Ether fuel of the present invention has the advantage of high cleanburning (thereby high clean emission) of dme and high-octane advantage of methyl alcohol simultaneously, therefore, this ether fuel can have octane value height, sufficient combustion, exhaust emission is low, and raw material is easy to get and advantage with low cost.Ether fuel of the present invention can satisfy the every requirement of automobile industry to gasoline, thereby replaces gasoline commonly used to use as the fuel of automobile.
More particularly, ether fuel of the present invention also has self-cleaning characteristics.Do not wish to be subject to concrete theory, the present inventor thinks because methyl alcohol has the good solubility energy, can effectively avoid at positions such as sparking plug, combustion chamber, valve, vapor pipe sourdine formation carbon deposit, prevent that oil circuit from stopping up, and avoid the fault that causes because of carbon deposit and obstruction, so produced automatic cleaning action.Be that ether fuel of the present invention can promptly be finished this self-cleaning function surprisingly under the situation of not adding any other additive except that dme and methyl alcohol.
Though ether fuel of the present invention has automatic cleaning action when not comprising purification agent, but because there is impurity in fuel itself, mix anvil cinder in production, transportation, the storage process, and the destabilization component in the fuel easily reacts, therefore generate settling easily, cause unstable idle speed, the accelerating ability variation, oil consumption increases, and noxious gas emissions such as hydrocarbon polymer, carbon monoxide and nitride increase.For further strengthening the cleaning action of ether fuel of the present invention, further increase the cleaning of oil piping system and the generation that reduces carbon on engine, ether fuel of the present invention can also contain purification agent.
The contriver finds that ether fuel of the present invention contains dme, methyl alcohol and purification agent succimide, has preferable automatic cleaning action.Succimide contains doping region and nonpolar district, and its doping region is surrounded the formation micella with established sedimental molecule, is distributed in the fuel, reaches the purpose of cleaning; Its nonpolar district is preferentially adsorbed on metal or ion surface, has formed one deck molecule protective membrane, has prevented the aggregation of particles deposition or in the metallic surface adhesion, has played the effect that keeps clean.Therefore, succimide can play the greasy filth of removing vaporizer and crankcase system and the effect of carbon distribution, minimizing is to the pollution of atmospheric environment, reduce the discharging of CO, reduce the discharging of HC (hydrocarbon polymer), can also reduce the wearing and tearing of oil pump and oil nozzle, prevent the spark plug coking, and the power of raising engine, thereby save energy, and the economy of raising fuel.
Up to now, tend to think succimide in the gasoline dope field owing to the thermostability deficiency, and can't when a small amount of the use, reach effective cleaning effect.Yet the present inventor against expectation finds, can use the succimide of lower level in ether fuel of the present invention, just can effectively improve the peace and quiet effect of ether fuel of the present invention.Though be not intended to be subjected to concrete theoretical restriction, the present inventor thinks, the reason that a small amount of in the present invention succimide can be played effectiveness can be done description below: first, different with the thermopositive reaction of regular price gasoline, the burning of ether fuel of the present invention is thermo-negative reaction, therefore, and during ether fuel combustion of the present invention, temperature when in-engine temperature is lower than gasoline combustion, this will reduce the decomposition of succimide.The second, owing to conventional oil, for example diesel oil and gasoline itself do not have peace and quiet effect, therefore work as succimide and are used for diesel oil and gasoline, need to use relatively large succimide, offset the peace and quiet effect reduction that the succimide pyrolytic decomposition causes.Yet in ether fuel of the present invention, because as mentioned above, this just has automatic cleaning action ether fuel of the present invention when not comprising succimide, and is therefore, less to the effective level requirement of succimide.Therefore, even because the hot conditions of engine, the effective content of succimide has reduced, and does not also influence the peace and quiet effect of succimide in ether fuel of the present invention.
In ether fuel of the present invention, be 100 weight parts in the gross weight of dme and methyl alcohol, the content of succimide can be the 0.005-0.02 weight part, preferably, the content of succimide is the 0.008-0.012 weight part.
Therefore, ether fuel of the present invention can be realized the effect of clean burning, cleaning discharging and protection vehicle.
Can reach the effect of regulating octane value by the content of dme and methyl alcohol in the adjusting ether fuel.Generally speaking, along with the content reduction of methyl alcohol, the octane value of ether fuel of the present invention also can decrease.But because the octane value of methyl alcohol itself is very high, therefore, under the situation of not using octane value properties-correcting agent, the octane value of ether fuel of the present invention all can be than higher.
Ether fuel of the present invention can not use any other additive, that is to say, ether fuel of the present invention can only be made up of dme, methyl alcohol and succimide.Yet, according to the needs of concrete application, also can add other component or additive, so that further improve some performance of gained fuel.
Because novel ether fuel of the present invention is different from conventional oil (for example gasoline and diesel oil), therefore, conventional gasoline dope might not can be used in ether fuel of the present invention.Before the additive with routine is used for ether fuel of the present invention, must at first carry out compatibility test.The compatibility test here is meant that additive to be used can be dissolved in the ether fuel of the present invention, and can keep stable existence, and does not change the proterties of ether fuel of the present invention.Have only the additive that those and ether fuel of the present invention can be compatible just might be used for ether fuel of the present invention.In addition, should be noted that also the adding of additive can not influence the special performance of ether fuel of the present invention significantly unfriendly, for example cleanliness etc.
The regular price gasoline additive that may be used for ether fuel of the present invention comprises, for example, and catalyzer, burning agent, antioxidant, ignition dope, purification agent and many octane promoters, metal passivator, inhibiter, deicing agent, anticorrosive agent, smoke suppressor etc.Through compatibility test after the assay was approved, these additives can be joined in the ether fuel of the present invention, condition is that the special performance that does not significantly influence ether fuel of the present invention unfriendly gets final product.The combination that also can add additive in ether fuel of the present invention, condition are that the special performance that does not significantly influence ether fuel of the present invention unfriendly gets final product.The contriver finds that by a large amount of tests some commercially available additive product can be used for ether fuel of the present invention, the ethanol gasoline detergent produced of petrochemical industry research institute for example, the fuel economizing purification agent that Si Te oil-saving agent factory in Xinxiang, Henan produces etc.
Except conventional additives, the present inventor finds that ether fuel of the present invention can also comprise water as ignition dope.Consider that the adding of avoiding owing to water brings impurity into, preferably use distilled water or deionized water.Do not wish to be subject to concrete theory, the combustion-supporting effect of water can be made description below: at first, water is (for example, under the petrolic condition) under high-temperature and high-pressure conditions, can decompose, and produces hydrogen and oxygen, and participate in reaction.Secondly, water is under the condition of engine chamber, and gasification is also expanded rapidly, thereby participates in the acting of expanding, and promotes contacting of fuel and air.
In addition, contain water in ether fuel of the present invention, particularly distilled water or deionized water the time, distilled water or deionized water have also played the effect of octane value properties-correcting agent.As previously mentioned, it is higher to comprise the octane value of ether fuel of the present invention of dme, methyl alcohol and succimide.Therefore, when ether fuel of the present invention contains distilled water or deionized water, can also regulate the octane value of ether fuel of the present invention, reduce octane value more specifically by adjusting the content of water.The present inventor finds, in ether fuel of the present invention, remains unchanged and is under the situation of 100 weight parts at the content of dme and methyl alcohol, and the water of every adding 1 weight part, the octane value of ether fuel will reduce about 1.0.
More particularly, the present inventor is through number of research projects, against expectation find in ether fuel of the present invention, to add 2, the 6-ditertbutylparacresol is as antioxidant, the colloid that can reduce ether fuel of the present invention autoxidation and produce, delay oxidized, prolong and guarantee the quality the time.When ether fuel of the present invention contained 2,6 ditertiary butyl p cresol, the content of 2,6 ditertiary butyl p cresol can be the 0.005-0.5 weight part, and preferred 0.01-0.1 weight part is based on the dme and the methyl alcohol total amount of 100 weight parts.
The present inventor finds, if contain Viscotrol C in the ether fuel of the present invention, then can further improve the function and the effect of this ether fuel.In ether fuel, Viscotrol C can play the effect of lubricant, viscosity modifier, promoting agent and sanitas.When ether fuel of the present invention contains Viscotrol C, can reduce the corrosion and the wearing and tearing of engine parts.The preferred content of Viscotrol C is the 0.5-1.5 weight part, based on the dme and the methyl alcohol total amount of 100 weight parts.
The contriver also finds surprisingly, in ether fuel of the present invention, contain succimide, Viscotrol C and 2 simultaneously, in the time of the 6-ditertbutylparacresol, these three kinds of additives can provide synergy, make that ether fuel mass of the present invention is more stable, the burning of fuel more fully, engine operating safety and power abundance.
Method for preparation ether fuel of the present invention is not particularly limited, and can obtain ether fuel of the present invention by the chemical field routine techniques.The preparation of ether fuel of the present invention comprises the adding of succimide, under the situation that comprises other optional additive, and the adding of other optional additive, and the mixing of dme and methyl alcohol.Generally speaking, succimide and other optional additive can be joined in the methyl alcohol, and then mix with dme.Yet, also can carry out the mixing of dme and methyl alcohol earlier, and then add succimide and other optional additive.For the back adds succimide and optional other additive, stir if desired, then should slowly stir.For the mixing of dme and methyl alcohol, can adopt absorption column of gas to obtain this mixing usually.Adopting absorption column of gas to carry out liquid, thereby the absorption of gas is obtained liquid is the routine techniques of chemical field with mixing of gas.The acquisition of ether fuel of the present invention is to adopt the method for physical absorption to obtain, and only relates to the absorption of methyl alcohol to dme.Generally speaking, select counter-current absorption usually, finish the preparation of ether fuel of the present invention.The present invention does not have any restriction for the selection on absorption tower, can select packing tower, tray column.Equally without any restriction, the chemical engineering technicians is in the face of methyl alcohol during to these specific purposes of absorption of gas of dimethyl ether for acceptance condition in the present invention, can be according to the basic chemical industry principle, and required relative content is selected absorption tower and acceptance condition.Usually, conventional normal temperature absorbs and can finish the absorption of methyl alcohol to dme.
This absorption process can be summarized as follows: make gas of dimethyl ether enter from the bottom, absorption tower through measuring fixed amount equipment (as gas distributor); Meanwhile, make methyl alcohol (perhaps being pre-mixed the methyl alcohol of succimide and other additive of choosing wantonly) add from cat head, gas-liquid two-phase is countercurrent flow in the absorption tower, and directly also abundant the contact, makes gas of dimethyl ether be absorbed by methyl alcohol.According to the selection on absorption tower and the difference of efficient thereof, can adopt one way to absorb or the circulation absorption.For circulation absorbs, can will get back to cat head and be incorporated in the tower from the methyl alcohol that contains dme that comes out at the bottom of the tower (and optional succimide and other optional additive of containing) conveying again, the gas that cat head is come out is carried again and is got back at the bottom of the tower and be incorporated in the tower, repeats the absorption process of gas of dimethyl ether thus.This multiple absorption can carry out repeatedly as required.Yet those skilled in the art also can know, the one way by the absorption tower absorbs and just can basically dme be dissolved in the methyl alcohol, obtain required dme content and need not multiple absorption.
The stability of ether fuel of the present invention is higher than regular gasoline far away.This can be proved from the inductive phase and the essence gum level of ether fuel of the present invention.
The present inventor finds that ether fuel of the present invention has high-octane rating, elevated oxygen level, low-steam pressure, low-sulfur, low benzene, low aromatic hydrocarbons and unleaded advantage.Ether fuel of the present invention can be used for existing vehicle, and need not to change engine structure.
A second aspect of the present invention
