The present invention relates to liquid combination, particularly comprise the mixture of gasoline and low-carbon alcohol.
Background technology
Gasoline belongs to petroleum chemicals, and a large amount of exploitations and the utilization of current petroleum resources have made the mankind face the serious situation that natural resources is about to exhaust.According to test and appraisal statistics, from from now on, global oil on average exploit to limit only be 30 years, the Middle East prospective oil is the abundantest, also only about 90 years, the North America is minimum, has only about 10 years, South America and China are about about 30 years in average the limit, and whole Asia average out to is about 15 years.So each state all takes much count of the development and the development and use of gasoline substitute.Make alcohol/oil production with methyl alcohol part gasoline replacing and make liquid fuel, be considered to a kind of economical and effective and up-and-coming behave.Methyl alcohol is a kind of reproducible clean fuel, can be described as inexhaustible, nexhaustible.The intermiscibility of methyl alcohol and gasoline is very poor, and the two mixes under normal conditions hardly, therefore needs to add auxiliary agent and could improve its intermiscibility, improves the various physicochemical properties that it acts as a fuel simultaneously.At present domestic as ground such as Shanxi, Henan, Sichuan, Xinjiang are all in the research and development application of this technology of work, but products made thereby is as automobile power fuel, it is lower to mix burning, generally about 20%, and the ubiquity physics and chemistry time is long, power is had disadvantageous effect, cold starting are smooth, exhaust emissions improves weak points such as not good enough, that economic benefit is obvious inadequately.
Summary of the invention
The present invention will solve the existing propellant combination that contains gasoline and make the existing problem that influences aspects such as cold starting, power, exhaust emissions of automobile fuel, a kind of propellant combination that contains gasoline of the present invention is provided for this reason, and this propellant combination is made its exhaust emissions of automobile fuel, with aspects such as gasoline interchangeability, cold starting, power last best performance is arranged all.
For addressing the above problem, the technical scheme that propellant combination adopted that the present invention contains gasoline is to contain gasoline, its special character is to be benchmark with this propellant combination weight, by gasoline 20～95%, methyl alcohol, ethanol, alcohol or glycol in this triol of furfuryl alcohol, the mixture 4.5～65% of triol, the trimethyl carbinol 0～3%, butanone 0～1%, Virahol 0～1%, isopropylcarbinol 0～1%, Ethyl Tertisry Butyl Ether 0～0.5%, methyl tertiary butyl ether 0～7%, tert amyl methyl ether(TAME) 0～0.5%, dimethyl carbonate 0～2%, ether 0～1%, isopropyl ether 0～0.5%, ethylene oxide 0～0.5%, oxidation inhibitor " 501 " 0～0.5% and water 0～0.5% mix to be formed.
Gasoline described in the present invention can be a kind of of No. 70～No. 90 gasoline or several mixture.
Described furfuryl alcohol is α-Fu Nan methyl alcohol (C
5H
6O
2).
The present invention adds described low-carbon (LC) alcohols in gasoline, gasoline just adjusts according to ambient air temperature with the ratio of alcohol, and purpose is to use gasoline as much as possible less, reduces blowdown simultaneously.In general, according to temperature, it is more appropriate that the part by weight of alcohol in total amount roughly is controlled at following scope:
-5～5℃????????????30％
5～15℃????????????35～40％
15～25℃???????????40～50％
25～30℃???????????50～60％
More than 30 ℃ 60～70%
Among the present invention, alcohols provides octane value, and ethers and ethylene oxide provide calorific value.
Component among the present invention all belongs to solvent or solubility promoter, and alcohols wherein is a low-carbon alcohol.Because gasoline and alcohols mutual solubility are poor, add the component of the present invention except that described gasoline and alcohols, can improve gasoline and pure mutual solubility, and can accomplish promptly to add instant, need not the physics and chemistry time.
The octane value of No. 70, No. 80 gasoline and calorific value are lower than gasoline No. 90, when the higher auxiliary agent of some ethers of an amount of increase and octane value can with No. 90 the same uses of gasoline.So among the present invention, 70,80, No. 90 gasoline is used alone or as a mixture, blending ratio what, according to the present invention and/or the art technology general knowledge, can be clear and definite.
Among the present invention, methyl alcohol, ethanol, furfuryl alcohol can use separately, also can be wherein two or three alcohol mix and use, if two mixing got half and half and get final product,, then respectively get 1/3 just passable if three mixed.Here, consider the performance of price, source difficulty or ease and the adding propellant combination of these three kinds of alcohol.At present, methanol prices be lower than 1,000 yuan in gasoline ±/ton, and see according to market situation from now on, gas price will rise, after methyl alcohol is used for composite fuels in a large number, methanol prices very likely can rise significantly, the ethanol price is unlikely to that then big rising is arranged, and it is such with present China Henan, Liaoning, to such an extent as to because grain comprises the big surplus of coarse cereals and corresponding tangerine bar output, can greatly develop alcohol production like this, the situation that the ethanol price is lower than methyl alcohol occur, so the present invention proposes to use ethanol, it uses separately or mixes use.The furfuryl alcohol low price, but its output is not high, it is met acid and can produce fibrous and mashed prod besides, but can pass through chemical treatment, and (this is the thing beyond the present invention, and the chemical field personnel can realize) used in reduction.When using furfuryl alcohol, should control the pH value below 6, and should add Virahol and/or isopropylcarbinol and/or dimethyl carbonate among the present invention.The furfuryl alcohol price is lower than methyl alcohol, is available raw material.
In-engine carbon deposit, be because the colloid of gasoline causes, the low-carbon alcohol and the solubility promoter (component among the present invention except that gasoline, alcohols can be referred to as solvent or solubility promoter) that in gasoline, add appropriate amount, can make colloid drop to 2% from 5%, and alcohols among the present invention and solvent or solubility promoter, itself be exactly good cleaning and thinner, therefore:
1. the carbon deposit of Mars chamber has not had, and has increased the intensity of igniting;
2. on the sealing break-in line of inlet and outlet door there be not the particle of charcoal, has increased tightness;
3. the carbon deposit of top land has not had, and has increased the volume of cylinder gas storage, and the fuel that enters cylinder has increased.
Thus, the power of automobile must increase, and automobile power increases, and oil consumption must descend.
