Abstract
A kind of abrasive alcohol gasoline and preparation method thereof, belongs to Fuel Petroleum oil field.The abrasive alcohol gasoline of the present invention, conveniently, long storage time is not also separated and deposited phenomenon, completely solves water content in oil and exceeds standard and cause high-clean gasoline generation phenomenon of phase separation for good stability, accumulating；The various ingredients added effectively prevent gasoline because using the problem of the engine combustion hydraulic performance decline of fuel combination, and can directly use, it is not necessary to electromotor does any change；Effectively reduce because of the too high corrosion to engine components of methanol content in methanol gasoline, improve service life of aeroengine；Effectively reduce the discharge of noxious pollutant, clean environment firendly after gasoline combustion.
Description
Technical field
The present invention relates to a kind of alcohol gasoline, particularly relate to a kind of abrasive alcohol gasoline and preparation method thereof.
Background technology
Along with the increase of population in the world and improving constantly of living standards of the people, the demand of the energy is increasingly powerful.Especially as developing rapidly of 20th century petrochemical industry in mid-term, accelerate the paces of energy industry development especially..The increase year by year of petroleum consumption, and the problem of environmental pollution that burning petroleum product oil causes is also increasingly severe, making fuel with refined oil, the carbon that contains in car exhaust gas, nitrogen, environment is caused great harm by oxygen sulfur compound, hydrocarbons.Meanwhile, this also makes traditional oil, natural gas resource day by day deficient, and according to investigations, the whole world is verified the oil of recoverable reserves and only can be used about 40 years, seeks alternative energy source and will become the key of future world economic development.
Alcohols is considered to have the fuel of internal combustion engine alternative fuel of application bright prospects, application at present mainly ethanol and part methanol.Ethanol is added in gasoline, it is possible to make ethanol petrol, but the production cost of alcohol fuel about 5000 yuan/ton, and producing cost is higher.And methanol production cost only has 1200 yuan/ton, compare better economic benefit.The second time oil crisis that the exploitation of external methanol gasoline and application start from the seventies in last century.Considering from the angle of alternative energy source, what moral, U.S., Deng state had successively put into that human and material resources carry out methanol fuel and methanol vehicle supporting technology grinds exploitation, and the ground such as California, USA and Germany has been also organized into methanol vehicle demonstration fleet.
Methanol gasoline anti-knock properties are good, and the toxicity of burning ejection is less than common doped fuel, and in aerofluxus, carbon monoxide content is also less.Because of methanol enriched oxygen content, sufficient combustion, combustion cleaning is functional.But general methanol gasoline is to petrolic corrosivity and the swelling ratio of elastomeric material is all relatively big, and low-temperature operability and cold-start performance are not as good as pure gasoline, and the key problem in technology core of methanol gasoline is technical merit and the quality control of additive.Further, since at present methanol gasoline have that corrosivity is relatively big, low-temperature stratification and chance water stratification.Because alcohol oil is hygroscopic, oil depot petrol station often has again water, preserve and use existence inconvenience.It addition, the latent heat of vaporization of methanol is about 3 times of gasoline, the high latent heat of vaporization and low vapour pressure will cause the problem such as mixed Daqu and starting difficulty.
For solving prior art problem, the present invention proposes one and gets clean alcohol gasoline and preparation method thereof clear.The problems such as methanol gasoline toxicity is big, be easily layered, storage is inconvenient can be solved.
Summary of the invention
The present invention is directed to the deficiency of current methanol gasoline application, it is provided that a kind of form is homogeneous, combustibility is good, non-corrosiveness, high-efficiency cleaning get clean alcohol gasoline clear.
