Description

The environmental protection and energy saving white gasoline

Technical field:

The present invention relates to a kind of environmental protection and energy saving white gasoline.It both can use separately, also can use with gasoline, was the desirable surrogate of white gasoline.

Background technology:

Along with high development of social economy, aspects such as transportation such as industry, agricultural, traffic need constantly to increase with fuel, and petroleum resources are more and more poorer, can't satisfy social requirement and market supply.Therefore,, seek a kind of ideal white gasoline surrogate, become one of important subject in the contemporary science and technology field from long-range viewpoint.The above white gasoline of 90# will become China's main automotive fuel.Therefore, according to this situation, I am through for many years development with great concentration, overcome outside the deficiencies in the prior art, it is simple to have developed a kind of technology, can operate at normal temperatures and pressures, does not have the environmental protection and energy saving white gasoline of three-waste pollution-can replace the white gasoline more than No. 90.

Summary of the invention:

The present invention is to be main raw material with methyl alcohol, adds ignition dope, detonator, octane value conditioning agent, oxidation inhibitor, purification agent and dispersion agent, produces the environmental protection and energy saving white gasoline by stirring.

The component content of environmental protection and energy saving white gasoline of the present invention is weight percentage, and wherein (1)-(4) gross weight is 100%, and (5)-(8) are by (1)-(4) gross weight 100%:

(1) main fuel 50～70%

The production technique of environmental protection and energy saving white gasoline of the present invention: at normal temperatures and pressures, press proportional quantity with main fuel, ignition dope, detonator, octane value conditioning agent, oxidation inhibitor, anti-corrosion additive, purification agent and dispersion agent, add stirred pot, stirred 5～15 minutes, both made the environmental protection and energy saving white gasoline.Performance and the effect of wherein various raw materials in prescription: methyl alcohol is that main fuel, the octane value of these environmental protection and energy saving white gasoline generally is higher than gasoline, the latent heat of vaporization, and vaporization heat is big.Contain aerobic in the methyl alcohol, required air quantity is few during burning, realizes perfect combustion easily, combustion exhaust CO measures decline, because its latent heat of vaporization is big, mixing institute's temperature when vaporization needs to descend, improved inner cooling conditions, reduced temperature simultaneously, thereby gassing factor improves, and has improved power function, waste gas alleviates the diluting effect of combustion gas, also have good knock rating, not leaded, possessed the condition of preparing the environmental protection and energy saving white gasolinees.The white alcohol of ignition dope plays and increases horsepower, the effect that improves the speed of a motor vehicle and explosive power.Detonator has played the effect that methyl alcohol can not direct starting, have easily start, characteristics that ignition characteristic is good.The octane value conditioning agent can improve the octane value of white gasoline, more than 90#, reaches as high as 98#, can promote dissolving each other of each raw material again, has solved the layering of white gasoline and has prevented the effect of oily group, also has the characteristics of ignition characteristic.Oxidation inhibitor and anti-corrosion additive to pure fuel caused various metallic corrosion played and suppressed effect preferably.Because alcohol is the polarity thing, have very high water absorbability, in preparation process, alcohol contains a spot of machine acid, is storing and also can form organic acid because of oxidation on.The existence of these acidic substance causes the corrosion of metal parts in the fuel, influences the life-span of engine.Therefore add oxidation inhibitor and anti-corrosion additive is absolutely necessary.Add purification agent and dispersion agent, do not have ash content after making the white gasoline burning, reached environmental protection and purpose of energy saving.

Environmental protection and energy saving white gasoline of the present invention, compared following remarkable advantage through driving experiment (actual experimentizing on Santana, motorcycle, east wind car) in recent years with existing existing technology:

The first, need not transform engine and existing white gasoline is used with, and not limited by ratio, also can use separately.The second, octane value does not reach as high as 98# up to 90#, and is leaded, do not contain benzene, do not pollute.When three, preparing, operation at normal temperatures and pressures, technology is simple, abundant raw material.Cost is low, and the rate of economizing gasoline height is easy to promote.Four, ignition characteristic is good, easily starts, non-oxidation, does not corrode the thermo-efficiency height.Its performance index all reach the GB17930-1999 standard.The 5th is the same with tank oil outward appearance, smell.The 6th, have good knock rating, security and stability.

When practical application, under the situation that oil rises steadily, if environmental protection and energy saving white gasoline of the present invention is all used in the big medium-sized city of China, the vehicle fuel of China has not just been deposited phenomenon in short supply.In view of this, economic results in society and the environmental benefit brought of development and use of the present invention all is beyond measure.
