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.
On the other hand, because the current mobility car is power fuel basically with gasoline, along with motor vehicle quantity constantly increases, its exhaust emissions is more and more serious to the pollution of air, directly affects people's living environment and healthy.With methyl alcohol part gasoline replacing, make methyl alcohol-gasoline mixed fuel, promptly alleged in the industry " methanol gasoline " is 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 inexhaustiblely, nexhaustible, but the intermiscibility of methyl alcohol and gasoline is very poor, the two mixes under normal conditions hardly, when adding suitable solubility promoter, then can improve its intermiscibility, and improve the various physicochemical properties that it acts as a fuel.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.
At present, the problem that mainly exists of preparation methanol gasoline has:
1. can not dissolve each other methyl alcohol and gasoline, one is water-based, and one is oiliness, and the two can not dissolve each other naturally, needs to add suitable solubility promoter;
2. calorific value is low because the calorific value of methyl alcohol only is 45% of a gasoline, if do not improve the calorific value of methanol gasoline, as automobile fuel, oil consumption will increase;
3. the automobile cold start difficulty is because the latent heat of vaporization of methyl alcohol is more than three times of gasoline, so use methanol gasoline, automobile start is difficult, when particularly temperature is low, through regular meeting the cold starting difficulty takes place;
4. vapour lock is used methanol gasoline, and vapour lock can take place for automobile oil circuit etc. when temperature is higher, and automobile also can stop working when serious.
The Chinese invention patent application specification of application number 01119418.9 discloses a kind of Vehicular methanol petrol, it is a main raw material with gasoline and methyl alcohol, add a certain proportion of ether compound and a spot of sanitas and purification agent, it is said to have fine pure oil phase dissolubility and cold startability.The disclosed a kind of Vehicular methanol petrol of the Chinese invention patent ublic specification of application of application number 01129132.X, it is except that containing methyl alcohol and gasoline, also have a small amount of trimethyl carbinol, tween, cerous nitrate and sulphonated oil, it is said that this methanol gasoline is not stratified in using, combustion efficacy is good, and the carbon monoxide and the oxynitrides of discharge obviously reduce than gasoline.A kind of methanol gasoline that the Chinese invention patent ublic specification of application of application number 01104115.3 discloses contains small amount of ethanol, dimethylbenzene and Dicyclopentadiene (DCPD), and the anti-knocking property of this methanol gasoline, good stability are not had corrodibility.The methanol gasoline that the Chinese invention patent ublic specification of application of application number 02113610.6 discloses contains solubility promoter alkylphosphonic acid carboxylic acid fat, ignition dope organometallic compound, and these product are stored not stratified, and burning is complete, and the exhaust emissions amount is few when automobile-used.The methanol gasoline that the Chinese invention patent prospectus of application number 03130822.8 is introduced, agent had acetone, zinc peroxide, ether, Methylal(dimethoxymethane), methyl tertiary butyl ether, octane during it added, it is said that to do the oil consumption of automobile power fuel low, power is strong, and carbon monoxide and oxynitrides discharging are few.We can say that the exploitation of existing methanol gasoline still is in the development trial period, seldom has practical high-quality finished product to appear on the market.
