Abstract
The present invention relates to an ethanol-sec-butyl alcohol-gasoline mixed fuel and a preparation method thereof. In the prior art, along with the shortage of petroleum resources and the continuously increasing petroleum price, the social and economic development requires resource, energy source and environmental revolutions; and the existing blending gasoline generally comprise methanol gasoline, ethanol gasoline and the like, the butanol production process requires a large amount of evaporation, heating and cooling facilities, the production cost is high, the investment is high, and secondary pollution on the environment can be caused. The ethanol-sec-butyl alcohol-gasoline mixed fuel comprises 25-50 parts by volume of ethanol, 50-150 parts by volume of sec-butyl alcohol, 250-350 parts by volume of gasoline, and 15-25 parts by volume of a cosolvent. The present invention provides the ethanol-sec-butyl alcohol-gasoline mixed fuel and the preparation method thereof.
Description
technical field:
the present invention relates to a kind of ethanol-sec-butyl alcohol-gasoline mixed fuel and preparation method.
background technology:
along with the shortage of petroleum resources, oil price rises steadily, and society and expanding economy require to carry out resource, the energy, environmental revolution; Existing blended gasoline has methyl alcohol, ethanol vapor wet goods usually, but needs in the preparation process of butanols to use a large amount of evaporations, heating, cooling infrastructure, and preparation cost is very high, invests very large and can produce secondary pollution to environment; Ethanol hydrophilic is better than lipophilicity, therefore needs to add solubility promoter when ethanol and gasoline mixing and just can obtain stable mixed solution, but the high incendivity that can affect fuel of solubility promoter ratio.
summary of the invention:
the object of this invention is to provide a kind of ethanol-sec-butyl alcohol-gasoline mixed fuel and preparation method.
above-mentioned object is realized by following technical scheme:
a kind of ethanol-sec-butyl alcohol-gasoline mixed fuel, its composition comprises: ethanol, sec-butyl alcohol, gasoline, and volume parts is: the volume parts of described ethanol is 25-50, and the volume parts of sec-butyl alcohol is 50-150, the volume parts of gasoline is 250-350, and the volume parts of solubility promoter is 15-25.
described ethanol-sec-butyl alcohol-gasoline mixed fuel, the volume parts of described ethanol is 25, and the volume parts of described sec-butyl alcohol is 50, and the volume parts of described gasoline is 250, and the volume parts of described solubility promoter is 15.
described ethanol-sec-butyl alcohol-gasoline mixed fuel, volume parts is: the volume parts of described ethanol is 50, and the volume parts of sec-butyl alcohol is 150, and the volume parts of gasoline is 350, and the volume parts of solubility promoter is 25.
described ethanol-sec-butyl alcohol-gasoline mixed fuel, volume parts is: the volume parts of described ethanol is 40, and the volume parts of sec-butyl alcohol is 100, and the volume parts of gasoline is 300, and the volume parts of solubility promoter is 20.
described ethanol-sec-butyl alcohol-gasoline mixed fuel, described ethanol to be concentration be 95 percent aqueous ethanol.
a kind of preparation method of the ethanol-sec-butyl alcohol-gasoline mixed fuel according to claim 1-5, first raw material is taken according to claim 1-5, then sec-butyl alcohol is joined in gasoline, fully be mixed to get Sec-butyl alcohol gasoline mixed solution, by concentration be again 95 percent aqueous ethanol join in Sec-butyl alcohol gasoline mixed solution, add solubility promoter again, fully after mixing, namely complete the preparation of this propellant combination.
beneficial effect:
1. the structure of the sec-butyl alcohol used in the present invention is branched chain type, and octane value is high, easier biological degradation, good environmental protection, and the anti-knocking property that can improve gasoline, can directly mix with gasoline by normal temperature; Sec-butyl alcohol is cheap, can directly buy.
be employed herein sec-butyl alcohol and aqueous ethanol, sec-butyl alcohol mixes with gasoline and reduces the ratio of gasoline in propellant combination, aqueous ethanol to join in propellant combination and only need add a small amount of solubility promoter ethanol and gasoline can be made fully to mix, because the content of solubility promoter is few, so the incendivity of propellant combination is improved.
the present invention has than simple gasoline or the better combustionproperty of ethanol petrol, and has the advantage of the energy and environment concurrently, can long storage time part layer; Preparation technology is simple, does not need to be equipped with a large amount of expensive Preparation equipment, and preparation cost is low.
