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 and methyl alcohol.More specifically, this ether fuel can only be made up of dme and methyl alcohol.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 methyl alcohol, and dme also is 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.

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 and methyl alcohol.
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 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 and methyl alcohol.Generally speaking, in ether fuel of the present invention, the content of dme can be the 4-12 weight part, and the content of methyl alcohol can be the 88-96 weight part, and wherein the gross weight of dme and methyl alcohol is 100 weight parts.Preferably, in this ether fuel, the content of dme is the 5-9 weight part, and the content of methyl alcohol is the 91-95 weight part, and wherein the gross weight of dme and methyl alcohol is 100 weight parts.
Below these two 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.
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 be finished this self-cleaning function surprisingly under the situation of not adding any additives.
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 additives, that is to say, ether fuel of the present invention can only be made up of dme and methyl alcohol.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 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, additive products such as the octane promoter that many fuel of ether therewith such as fuel economizing purification agent that Si Te oil-saving agent factory in Xinxiang, Henan produces can be compatible, catalyzer, burning agent, antioxidant, ignition dope, metal passivator, inhibiter, deicing agent, anticorrosive agent, smoke suppressor.
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 enhancing additive.As previously mentioned, it is higher to comprise the octane value of ether fuel of the present invention of dme and methyl alcohol.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
Though ether fuel of the present invention has automatic cleaning action, but be the cleaning action that further strengthens 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, preferably adds succimide in ether fuel of the present invention.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 improve the power of engine, thereby save energy, and improve fuel economy.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.
The contriver also finds surprisingly, in ether fuel of the present invention, contain Viscotrol C, succimide 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 is included under the situation that comprises additive, the adding of additive, and the mixing of dme and methyl alcohol.Generally speaking, 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 additive.For the back adds 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, 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 additive) add from cat head, gas-liquid two-phase is countercurrent flow in the absorption tower, and directly and fully contacts, and 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 the optional additive that contains) 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
In a second aspect of the present invention, the present invention relates to a kind of propellant combination, comprise ether fuel of the present invention and other fuel, for example gasoline.
The contriver finds, the ether fuel of the present invention use that can act as a fuel separately is used for engine, particularly petrol engine.Therefore, ether fuel of the present invention fully gasoline replacing be used for automobile fuel.Yet also gasoline that ether fuel of the present invention and routine can be used, and even methanol gasoline or ethanol petrol mix use, are used for the fuel of automobile fuel or other vehicles or power-equipment.When ether fuel of the present invention and gasoline were mixed, the blending ratio of ether fuel of the present invention and gasoline can be regulated arbitrarily as required.
Generally speaking, in the propellant combination of second aspect present invention, the content of ether fuel of the present invention can be for 1-99 weight %, based on the gross weight of propellant combination.Preferably, the content of ether fuel of the present invention can be for 10-90 weight %, based on the gross weight of propellant combination.

In this application, regular gasoline is meant and does not add dme, methyl alcohol or alcoholic acid gasoline.Methanol gasoline and ethanol petrol are meant respectively and have added methyl alcohol or alcoholic acid gasoline.Owing to added methyl alcohol in the methanol gasoline, when ether fuel of the present invention and methanol gasoline were mixed use, the methyl alcohol that has in the methanol gasoline can change the dme and the methyl alcohol ratio of ether fuel of the present invention.Therefore,,, need to consider the methanol content in the methanol gasoline, finally determine the blending ratio of ether fuel of the present invention and methanol gasoline according to actual conditions and purposes ether fuel of the present invention and methanol gasoline being mixed when using.Perhaps, ether fuel of the present invention and methanol gasoline are being mixed when using, according to actual conditions and purposes, need to consider the methanol content in the methanol gasoline, can not cause that the content ratio of dme and methyl alcohol departs from scope of the present invention in the ether fuel of the present invention so that guarantee the introducing of methyl alcohol in the methanol gasoline.Generally speaking, in order to make dme content in the ether fuel of the present invention be in the preferable range of 5-10 weight part (with the total of 100 weight part methyl alcohol and dme) for example, when using methanol gasoline, the blending ratio of methanol gasoline should not surpass 50%.
For example, methanol gasoline contains the methyl alcohol of 15 weight %, mix the ratio that to consider dme used herein when using, and the effect of dme in this ether fuel, guarantee the fuel performance in the mixed propellant combination, then the blending ratio of methanol gasoline should not surpass 50% of ether fuel of the present invention.
Generally speaking, ether fuel of the present invention can be mixed with arbitrary proportion with regular gasoline.Preferably, ether fuel of the present invention and regular gasoline are mixed with 10: 90 to 90: 10 part by weight.More preferably, ether fuel of the present invention and regular gasoline are mixed with 30: 70 to 70: 30 part by weight.
When the blending ratio of ether fuel is up to 90%, i.e. 90 weight parts ether fuel of the present invention and the regular gasoline (for example No. 93 gasoline) of 10 weight parts when mixing, resulting propellant combination steady quality, the quality guaranteed period reach 2 years not stratified.
, perhaps mix with methanol gasoline or ethanol petrol when using with 30% ratio and regular gasoline at ether fuel of the present invention, can also reach the effect that improves power and fuel saving with 20% ratio.Under the engine working conditions of same operating mode, the saving ratio of fuel can be up to more than 10%.Use ether fuel of the present invention and gasoline to be mixed, alternative ratio can be brought up to 0.7 to 1 (the alternative ratio of ethanol petrol is 1.6-1.7).Here, alternative ratio is meant the ethanol petrol of a regular gasoline needs of replacement or the weight part of ether fuel of the present invention.And, use ether fuel of the present invention, can be so that the exhaust emissions amount reduce greatly, thus excellent environment protecting is provided.
As mentioned above, because the octane value of ether fuel of the present invention is higher,, therefore, can use ether fuel of the present invention to improve the label of regular gasoline usually more than 100.For example, can use ether fuel of the present invention to make No. 90 gasoline or No. 93 gasoline reach the standard of No. 93 or No. 97 gasoline respectively.
In addition, use ether fuel of the present invention can also improve the stability of regular gasoline.Generally speaking, the stability of commercially available regular gasoline is good inadequately.With ether fuel of the present invention and commercially available regular gasoline compounding, can improve the inductive phase of regular gasoline and reduce gum level.
Generally speaking, in the propellant combination of second aspect present invention, if added water in the ether fuel of the present invention, having of water may cause gasoline emulsification, or even layering.May limit the use range of propellant combination of the present invention like this, and for example can't be used for electronic fuel injection engine, and can be used for carburetor engine.Therefore, preferably when mixing use with gasoline, do not contain water in the ether fuel of the present invention.
Be not specifically limited for the method that obtains propellant combination.Can obtain propellant combination by ether fuel of the present invention is mixed with gasoline.For example, ether fuel of the present invention can be joined in the gasoline, perhaps gasoline be joined in the ether fuel of the present invention, perhaps ether fuel of the present invention and gasoline be joined in the independent container simultaneously, and mix, obtain propellant combination.This mixing can obtain under the slow condition of stirring of employing.
