Description

Automobile-used high definition environmental protection alcohol ether fuel

Technical field

The present invention relates to a kind of fuel liquid for automobile, particularly a kind of automobile-used high definition environmental protection alcohol ether fuel that is main raw material with methyl alcohol, ethanol or the first and second alcohol mixtures.

Background technology

The world today, the energy and environment are the principal elements affecting global economy social sustainable development, and the energy is the basic substance of human survival and Economic development.But, along with world economy continue, development at a high speed, the problems such as energy shortage, environmental pollution, ecological degeneration are more and more outstanding.According to scholarly forecast, by current consumption, oil, Sweet natural gas can only maintain less than half a century at most, and coal also can only maintain 100 or two hundred years, so no matter be any conventional energy resources structure, the energy dilemma of facing mankind is all on the rise.

As everyone knows, the national conditions of China are oil starvation, weak breath, relative rich coal, and the most important condition of substitute energy must possess two large factors: one is rich reserves, and two is that burning is clean.But but there are the coal-seam gas of abundant high sulphur coal and rich reserves and the byproduct coke(oven)gas of coking charcoal in China, them therefore can be utilized to make the derivative product of the fuel such as methyl alcohol, dme and much methyl alcohol.

Chinese Academy of Geological Sciences's " Mineral resources and Chinese Economy Development " just proposes in reporting: the existing reserves of Chinese postman problem algorithm are by the consumption less than 30 years, and ultimate recoverable reserves can maintain consumption in 50 years reluctantly; To the year two thousand twenty, the import volume of CNPC will more than 500,000,000 tons, Imported gas will more than 1000 billion cubic meters, both external dependence degree will reach 70% and 50% respectively, this seriously injures the national energy security of China, once international situation is unstable or outburst war, energy importation channel is destroyed or cut off, national economy high-speed cruising system will be severely affected and occur that big area is paralysed, and its consequence is by hardly imaginable.

In the reserves that China's energy is verified, coal is that main body accounts for 94%, and oil accounts for 5.4%, natural gas station 0.6%.Although coal in China output accounts for 36.5% of Gross World Product, coal reserves only accounts for 13% of world saving, and under China's existence conditions, the limit of coal annual production is 2,000,000,000 tons, and the coal Year's consumption of China is more than 1,300,000,000 tons, approaches the limit, within sight.

According to statistics, current China motor vehicle is possessed total amount and has been reached 2.25 hundred million, and all remains the annual growth of more than 20% every year, becomes national economy new growth point, has important strategic position in national economy.

Two conclusions are drawn: one is that energy shortage moves towards power consumption gradually from above-mentioned data; Two is main energy sources of using at present has severe contamination for the environment of human survival.So the energy dilemma forward mankind attack, various countries are to the contention of the energy, the major cause that will be following global conflicts.

The energy strategy of China is also " economization at first, bases on our country, based on coal, multiple development ".Thus established solid basis for the further expanding production of the development of methanol fuel and carbinol derivatives product, output.Although all achieve interim achievement for many years in the research and utilization of methanol fuel, but because of the restriction by the peculiar property of alcohol ether class A fuel A, cause in the research to high density Aalcohols fuel, substantially be by transforming existing spark ignition engine or methanol fuel special engine and reach the requirement adapting to high density Aalcohols fuel, and play the advantage of Aalcohols fuel.

Methyl alcohol and ethanol are a kind of excellent polar organic solvent, their many character all with gasoline relatively, although their calorific value is all much lower than gasoline, but the no matter propellant combination of which kind of ratio, the calorific value (MJ/Kg) of theoretical mixture gas is all not less than gasoline and is approximately higher than gasoline (methyl alcohol 3.08, ethanol 3.00, gasoline about 2.92), susceptibility is then little than gasoline simultaneously, and octane value RON or MON is but a little more than gasoline.Therefore, Aalcohols fuel may be used for the engine of higher compression ratios and unlikely generation pinking, and can improve the efficiency of engine.When particularly alcohol ate works under rich mixture condition, tendency to detonate is also very little.During as used host fuel as engine of methyl alcohol or ethanol, owing to containing more oxygen in first, ethanol, in addition alcohol ate content is higher, fuel octane number increase rate is larger, and the combustion limits of Aalcohols fuel are very wide, particularly the burning concentration upper limit is more much higher than gasoline, therefore can obtain high-level efficiency and very strong driving force on the engine adapting to high compression ratio.Aalcohols fuel utilization ratio compared with general-utility car fuel of high density is high, and pollute few, ozone is formed less, and is easy to store and carry, and the fuel being therefore commonly used for racing car and high-power Der Gelaendewagen uses.

But when methyl alcohol, ethanol are as vehicle fuel, also there are many defect parts.If the latent heat of vaporization of first, ethanol is respectively than high 2-4 times and 1-1.4 times of gasoline, although can inlet air temperature be reduced, improves charging efficiency, bring difficulty to cold start-up, cause carburettor icing, the problems such as fuel consumption increase.

And for example the boiling point of methyl alcohol and ethanol exceeds 30 DEG C and about 43 DEG C respectively than the initial boiling point of gasoline, but it is more much lower than the final boiling point of gasoline, therefore, when using methyl alcohol or the alcohol fuel of high density, in engine working process, methyl alcohol and ethanol can evaporate completely, form more uniform gas mixture with air.But the vapo(u)rability of alcohols is very poor at low temperatures, vaporization heat is large in addition, reduces inlet temperature further during evaporation, and cause cold start difficulty or warming up time to lengthen, oil consumption increases.In addition, methyl alcohol has certain electroconductibility, and liquid methanol, once enter cylinder, easily adhering in plug ignition gap, causes loss of ignition.Have resource to show, do not taking under the condition helping igniting measure, high concentration methanol or alcohol fuel in the minimum start-up temperature of engine respectively at 0-16 DEG C and about 15-20 DEG C.

For another example, the saturation steam pressure ratio gasoline of methyl alcohol and ethanol is much lower, but the saturated vapor pressure of propellant combination is not with the increase of alcohol content in the relation of simple decrease, and the saturated vapor pressure of methanol gasoline or ethanol petrol is increase with methyl alcohol or ethanol content and increases.Roughly reach maximum value when methanol content is 15% and ethanol content is 12%, increase with methyl alcohol or ethanol content and reduce afterwards.When methanol content is lower than certain value, the saturation steam pressure ratio gasoline of methanol gasoline also want large, occur that the reason of this phenomenon is because methyl alcohol can form the cause of the low azeotrope that boils with the lighting end in gasoline, this phenomenon makes the vaporization losses of low ratio methanol gasoline in storage increase, and easily produces vapour lock when using under high temperature.The saturated vapor pressure of ethanol petrol propellant combination and have similar relation containing between oxygen.

In addition, methyl alcohol and the many metals of ethanol to engine fuel system are all corrosive, and they can corrode copper, iron, aluminium, lead, zinc, magnesium and their many alloys.Even if propellant combination also makes the corrodibility of fuel greatly strengthen containing the alcohol of 3%, alcohol content more highly corrosive is larger.Prevent the Basic Ways of alcohol ate corrode engine metal from having two, one is change engine metal material, corrosion resistant metal is used to manufacture engine, but the method cost is high, two is add anticorrosive additive in fuel, and method is feasible, easy, cost is low, effective, facts have proved, in alcohol ate, add a small amount of sanitas just effectively can prevent metallic corrosion.

Alcohol ate, except being corrosive to metal, also has burn into swelling action to rubber and plastic components.Engine fuel system mass part is all rubber, plastic or other material is made, in alcohol ate can swelling, become sticky or chap; Oil fuel pump barrier film and fuel hose are rubber items, also can occur in alcohol ate swelling, hardening, become fragile or the phenomenon such as softening; Fiber mat sector-meeting is softening gradually and cause leakage of oil.So, in alcohol ate, add some additive also can reach or alleviate alcohol ate to the corrodibility of rubber, plastic component and swelling, aging restraining effect.

The current patent application for alcohol-ether fuel mainly comprises additive and the alcohol-ether fuel of alcohol-ether fuel:

The present invention is for main raw material with methyl alcohol or ethanol or the first and second alcohol mixtures, by being equipped with 14 kinds of multipurpose additives, efficiently solve high-content, high density first and second alcohol ate because of many defects that its intrinsic characteristic is brought, be embodied in the following aspects when using in existing spark ignition engine:

1, methanol fuel or alcohol fuel because of calorific value low, the latent heat of vaporization again respectively than gasoline height 2-4 doubly and 1-1.4 times, although can inlet air temperature be reduced, improve charging efficiency, but the vapo(u)rability at low temperatures because of Aalcohols fuel is very poor, reduce inlet temperature further during evaporation, cause cold start difficulty or warming up time to lengthen, oil consumption increases.The present invention, by after adding the raw materials such as appropriate ethers, hydro carbons, lipid, achieves the close of this fuel value and gasoline heat value.

As for the dimethyl ether in Aalcohols fuel ether stablizer, its advantage is:

1. dme post liquefaction is as vehicle fuel, the shortcoming of methanol fuel or alcohol fuel low-temperature startup and accelerating ability difference can be overcome to a certain extent, after adding dme, methanol fuel or alcohol fuel is made to be provided with excellent ignition properties, and delay period of ignition is short, engine mildness, not easily produce rough running phenomenon, work noise is little.

2. dme is oxygenated fuel, and completely, the discharge of itself CO and HC is more a lot of than vapour, diesel oil cleaning, almost can realize smokeless combustion in burning.As long as when fuel oxygen level reaches more than 34%, engine does not all generate soot under any operating mode.Due to fuel band oxygen itself, make the oxygen molecule distribution uniform in whole combustion chamber, particularly dme vaporization heat is large, also combustion chamber top temperature can be reduced, thus the discharge of NOx is especially effectively decreased, when adopting engine exhaust exhaust secondary recycling, the discharge of soot will be zero, and the discharge of NOx also obtains significantly reducing further.

Although 3. the low heat value of methyl alcohol, dme is all low than vapour, diesel oil, but the calorific value of its theoretical mixture gas and gasoline, diesel oil close to or slightly high (methyl alcohol 2656KJ/Kg, dme 3067KJ/Kg, gasoline 2786KJ/Kg, diesel oil 2911KJ/Kg), after the two allotment, the theoretical mixture gas calorific value of alcohol-ether fuel and gasoline theoretical mixture gas calorific value remain basically stable or slightly high.In addition DME combustion speed is fast, and thermo-efficiency is high, and completely, therefore dynamic property is poor unlike vapour, diesel oil in burning.In fact, because dme is containing oxygen, air-fuel ratio required during burning is little, when air inlet amount is identical, and the fuel that Ke Yi Gong Give is more, therefore, taller when during dimethyl ether fuel, dynamic property ratio uses gasoline and diesel oil.

Meanwhile, the present invention, by adding carbonyl carboxylate and the nitro ester compound of 1-40 part in alcohol-ether fuel, not only serves good catalytic combustion-supporting effect to Aalcohols fuel, and also has obvious auxiliaring effect in cold-starting etc.Carbonyl carboxylate chemical property is active, particularly simultaneously containing the multiple functional group such as carbonyl, hydroxyl, methoxyl group and methyl, can with alcohols generation methylation reaction and carbonylation reaction, generate multiple derivative, thus reduce the latent heat of vaporization of methanol fuel, improve energy transformation ratio.Experimental data shows, within the scope of some amount, when the usage quantity of carbonyl carboxylate is often more than 1%, the latent heat of vaporization of methanol fuel can reduce by more than 30%, and oil consumption can reduce 2-5%, and dynamic performance is significantly improved, but combustionvelocity about has decline.In addition carbonyl carboxylate is also good slip additive, in alcohol ether comburant (-rent), add appropriate carbonyl carboxylate, effectively can change the lubricity of alcohol-ether fuel, reduce frictional coefficient and the degree of wear of engine further, thus reduce power loss, improve energy transformation ratio.

In addition, by adding nitro ester compound simultaneously, the Catalytic Combustion Effect of alcohol-ether fuel becomes more obvious, thus all serves certain effect to the minimizing of the combustionproperty of alcohol-ether fuel, exhaust emissions, CO and HC.

2, Aalcohols fuel because of boiling point on the low side, easily there is vapour lock when hot operation or engine continuous long-play, cause the smooth or fuel cut-off of fuel feeding.The present invention is by after adding the raw materials such as the higher and wider ethers of appropriate boiling range scope, mixed alcohols, carbonyl ester class and nitro ester, make the whole combustion processes of alcohol-ether fuel all reach the whole trouble-free burning operating requirement of spark ignition engine, solve vapour lock problem.

Because add nitro ester compound, the effect of the hydrocarbyl portion of nitric ether is easily decomposed into alkoxyl group (RO), and the NO in molecule ₂part is easy to react with alkyl, thus makes the combustionproperty of alcohol-ether fuel be further improved, and delay period shortens, and rate of combustion improves.Adding in addition again because of carbonyl carboxylate, for methylcarbonate, it has excellent solubility property, not only good with the intermiscibility of other solvents, not stratified, also there is higher vaporization temperature and the feature such as velocity of evaporation is fast, and the oxygen level in molecule is up to 53%, is also improved the function of octane value.Methylcarbonate due in its molecule containing multiple functional group, carbonylation can be carried out at multiple fields, methylate, esterification, carbomethoxy and transesterify, the chemical reactions such as hydrolysis can be there is, and generate the fine chemicals of multiple important high added value.Particularly carbonyl wherein and methyl, when the carbonyl carbon of methylcarbonate is subject to nucleophillic attack, acyl group-oxygen bond rupture, forms carbonyl compound; When its methyl carbon is subject to nucleophillic attack, base alkyl-oxygen bond rupture causes methylate to generate.With various alcohol for raw material and dimethyl carbonate, various asymmetric methyl ether can be obtained.And as solvent, its fusing point, boiling spread is narrow, surface tension is large, viscosity is low, dielectric permittivity is little, good anti-static effect can be obtained, vaporization heat is low, and due to relative evaporation speed fast and there is rapid-drying properties, solubility parameter SP value and acetone close, and it is good with the intermiscibility of gasoline, with other solvent phase ratio, it is high that methylcarbonate also has flash-point, steam forces down, Lower Explosive Limit high in air, in storage, use middle security high, its toxicity data is better than other solvent, little to the harm of human body, carbonyl carboxylate or preferably slip additive simultaneously, the carbonyl carboxylate adding some amount in alcohol-ether fuel can change the oilness of fuel, reduce wearing and tearing and the friction of engine, and avoid the methyl alcohol of non-vaporizing section or ethanol to flow into casing wall, thus reduction power loss, improve energy transformation ratio.

3, methyl alcohol and ethanol are a kind of excellent polar organic solvents, have stronger chemically reactive.The formic acid produced in combustion or acetic acid, the metal materials such as copper, aluminium, manganese can be made to produce corrosion, and these materials are typical materials of Fuel Petroleum automobile.Meanwhile, the formic acid produced in combustion processes or acetic acid also produce softening or be full of cracks effect to the non-metallic material of automobile sealed rubber and other synthesis, and make these material premature agings.The present invention by adding the raw material of the swelling suppression of corrosion of appropriate metal cleaning, inhibition, the suppression of metallic corrosion and rubber, plastic component in alcohol-ether fuel, make the corrosion degree of swelling of alcohol-ether fuel of the present invention to corrosion of metal degree and rubber member all drop to very low scope, make the problems referred to above obtain fine solution.

4, because of the very easily water absorption character of Aalcohols fuel, thus when temperature reduces or lighter hydrocarbons solvent oil and other auxiliary agent because of after moisture content exceedes certain index, easily there is liquid phase separation, thus cause the normal use affecting fuel.Alcohol-ether fuel of the present invention is by adding appropriate ethers, mixed alcohols, solubility promoter and bipolarity or multiple polar group raw material, substantially increase the resisting phase separation effect of fuel, and the highest temperature of dissolving each other can be reduced to less than-30 DEG C, thus fully ensure the burning result of use of alcohol-ether fuel of the present invention.

5, the complete skill scheme that formed of the raw material of specific components of the present invention and proportioning, by the interaction of each raw material,

The octane value achieving alcohol-ether fuel with a label 3-5 unit, is particularly useful for the engine of high compression ratio higher than GB gasoline octane rating, has good stability, dynamic property strengthens, the technique effect that oil consumption reduces.Energy-conservation 3-8% compared with regular gasoline, and use mix the alcohol-ether fuel of burning more than 15% in regular gasoline after, then can reduce rate of fuel consumption more than 10%.Meanwhile, the present invention also can reduce the discharge of CO and HC in tail gas greatly, and noise reduces, and has good scavenging(action) to the carbon distribution of firing system and throw out, extends the work-ing life of engine.

Meanwhile, owing to not containing many objectionable impuritiess in alcohol-ether fuel of the present invention, as lead, sulphur, benzene, alkene, manganese etc., be thus more conducive to the standing storage of fuel, also for transport for a long time, sale provide guarantee.

Obviously, according to foregoing of the present invention, according to ordinary skill and the customary means of this area, under the prerequisite not departing from the above-mentioned basic fundamental thought of the present invention, the amendment of other various ways, replacement or change can also be made.

The embodiment of form by the following examples, is described in further detail foregoing of the present invention again.But this should be interpreted as that the scope of the above-mentioned theme of the present invention is only limitted to following example, all technology realized based on foregoing of the present invention all belong to scope of the present invention.
