Description
Technical field
The present invention relates to alcohols substitute fuel field, more particularly to a kind of biological alcohol-based light Fuel flash-point Improve agent.
Background technology
For a long time, always based on gasoline, diesel oil, this use pattern is increasingly subject to ring to the fuel of all kinds of motor vehicles
Border is seriously polluted and resource restriction increasingly in short supply.In order to improve this predicament, various energy resources alternative is employed both at home and abroad,
However, these alternatives all have serious defect to large-scale promotion.In addition, diesel engine is in its exhaust
Containing a large amount of particles, these particulates are mainly and are made up of black carbonaceous material, and the rate of settling is very low, can long-term suspension in air
In, serious haze is caused, greatly harm is caused to human health.
Alcohols fuel oil is subject to weight as one kind cleaning, cheap, efficient fossil fuel substitute with its abundant source
Depending on, it is considered to be most promising fossil fuel substitute fuel.Nobel chemistry Prize winner George A Auras in the U.S. pass through
Study for a long period of time and think that " methyl alcohol economy " makes the mankind be no longer dependent on the oil and natural gas methyl alcohol for increasingly reducing fuel as an alternative.
Progressively bright and clear in the development prospect of China, methyl alcohol boiling point is lower than diesel oil, mixed Daqu speed, and than more uniform,
Be conducive to burning completely；Methyl alcohol oxygen content accounts for 50%, and its inflammability limit is wide compared with diesel oil, and burning velocity is high, advantageously reduces smoke evacuation.
But, methyl alcohol has following unfavorable factor as alternative fuel for diesel engine：(1) it is polar substances due to containing hydroxyl in methyl alcohol,
So methyl alcohol and diesel fuel ratio are more difficult, whether mix by pressure, or add a certain amount of cosolvent, can not all protect
The uniform mixing of card methyl alcohol and diesel oil, fuel combination is easily layered, less stable；(2) burning-point of methyl alcohol is up to 470 DEG C, compares bavin
200~220 DEG C of oily burning-point is much higher, therefore methyl alcohol is both difficult to compression ignition, is not easy to be ignited, and the ability of spontaneous ignition is poor；
(3) latent heat of vaporization of methyl alcohol is big, and the operating mode when cooling effect that the latent heat of vaporization high is produced is to low engine speed, underload can be produced
Adverse effect；(4) viscosity of methyl alcohol is low, directly during fuel injection system original using diesel engine, can cause system wear, very
Extremely stuck etc. failure, so as to influence the reliability and durability of engine.In addition, due to the methyl alcohol low characteristic of flash-point in itself
(methyl alcohol flash-point is 12 DEG C, much lower for 55 DEG C of Flash Point of Diesel), makes its transport, storage have received greatly limitation,
Thus constrain the development of alcohol-based fuel.As can be seen here, improve methanol fuel flash-point, build one kind can by it is carbinol-modified,
Methyl alcohol is turned into the additive of safety fuel, could fundamentally solve the problem that alcohol-based fuel is restricted.
The index for evaluating the security of light Fuel is mainly the flash-point (Flash Point) of fuel, refers in regulation
Under the conditions of, heating sample, when sample reaches certain temperature, the steam of flammable liquid with the gaseous mixture of air closing on flame,
There is the minimum temperature of sample during of short duration scintillation；Scintillation is small blast, it is meant that oil product volatilization at this temperature is produced
Oil vapour has reached the concentration needed for exploding in atmosphere, and only the volume fraction of imflammable gas reaches a fixed number in gaseous mixture
During value, meeting fire could explode, and concentration is too small or excessive all without exploding.55 DEG C of the flash-point of diesel oil is, it is necessary to extraneous heating
The phenomenon of scintillation can occur, and the flash-point of methyl alcohol is only 12 DEG C, that is to say, that without heating, methanol liquid temperature summer just
12 DEG C can be reached, now methyl alcohol meets naked light just the possibility of blast；And after a small amount of methyl alcohol is mixed with fuel, the combustion of its alcohol radical
The flash-point of material is rapidly reduced near the flash-point of methyl alcohol (12 DEG C)；All the time " the low-flash principle of mixed solution " is follow, is caused
The flash-point of light Fuel is solved the problems, such as, is global bottleneck problem；As can be seen here, the flash-point of methyl alcohol is improved, improves alcohol radical combustion
The security performance of material, is to be related to the great difficult problem that can Aalcohols fuel smoothly be promoted.
Many so-called environment-protective biodiesel, such as patents of high cleanness methanol diesel, Patent No. are occurred in that in recent years
CN101955810A, discloses a kind of " green environment protective biological diesel oil ", Patent No. CN101205487A, discloses a kind of " first
Alcohol diesel oil ", Patent No. CN102134516A, disclose a kind of " high cleanness methanol diesel and preparation method thereof " and Patent No.
CN101709234A, discloses a kind of " methanol diesel fuel complex additive and preparation method ", but above-mentioned patent is equal in the content
The flash temperature of the embodiment dare not be referred to, some patents are referred to flash-point Improve agent, but not specify its action principle simultaneously,
Actual measurement flash-point data are not referred to, do so is played for the gallery nothing but, it is fundamentally low again without methanol diesel-oil flash-point is solved
Problem.Patent No. CN101886000A, discloses a kind of " preparation method of methanol diesel-oil ", and the flash-point of its embodiment is equal
Between 45 DEG C~55 DEG C, but oil product manufacture craft is cumbersome, and required equipment requirement is very high, and process regulation is strict, is unfavorable for
Mass produce and use.As can be seen here, a kind of few consumption, low cost are researched and developed, good effect, process is simple, can be dropped with biology
Xie Xing, without harm composition, will not cause the novel environment friendly flash-point Improve agent of secondary pollution to become extremely urgent to environment.
