Abstract
The invention discloses a high proportion car-used methanol fuel additive, relates to car-used methanol fuel additive and a component of fuel, and belongs to the field of energy chemical engineering. The high proportion car-used methanol fuel additive is characterized by comprising the following ingredients in volume percentage: 0-15% gasoline, 85-99% car-used fuel methanol, and 0.5-2.0% high proportion car-used methanol fuel additive TP. The high proportion car-used methanol fuel additive has the benefits that the mixed fuel of two alcohols, gasoline, and additive is adopted by the fuel provided by the invention; the methanol and the ethanol have complementary functions on aspects of burning and dissolution during use; in the presence of water, the miscibility of the ethanol and the gasoline is better than that of the methanol and the gasoline; the ethanol, like the higher alcohol, is an additive for methanol gasoline mixed fuel; and the dynamic performance is strong, and the pollution discharge amount is reduced.
Description
Technical field
The present invention relates to a kind of component of the used methanol fuel additive of automobile and fuel, belong to the derived energy chemical field, specifically a kind of vehicle methanol fuel additive at high proportion.
Background technology
Along with the fast development of global economy, China's automobile industry has also obtained develop rapidly.But increasing sharply of communications and transportation and automobile pollution caused great pressure for China's energy resource supply and environmental pollution.On the one hand, traditional gasoline, diesel motor are faced with the petroleum resources problem of shortage; On the other hand, the topsoil that motor vehicle emission causes is on the rise, the big and medium-sized cities in various countries, and the motor vehicle emission tail gas pollution has become the main source of pollution of topsoil, and they have caused common people's concern to the harm of HUMAN HEALTH.
In order to alleviate the pressure that the petroleum resources shortage brings, improve atmospheric environment, promote the Sustainable development of human society and automobile industry, exploitation new energy sources for automobile and new power have become the ten minutes urgent task that automotive industry faces.Aalcohols fuel (methyl alcohol, ethanol) as novel fuel substitute appear at people in face of.Use alcohols etc. substitutes the alternative or partly alternative conventional gasoline of fuel, diesel oil, combustion cleaning not only, can reduce conventional emission of harmful substances significantly, make the emission concentration of wherein hydrocarbon polymer (HC), oxynitrides (NOX), carbon monoxide (CO), carbonic acid gas (CO2) and particulate matter that significant reduction be arranged, have good environmental protection characteristic; And the source of Aalcohols fuel is also very abundant, is desirable oil replacement product.Therefore, under the dual-pressure of environmental protection and the energy, Aalcohols fuel presents development prospect widely as the novel energy of automobile.
At present, in the Aalcohols fuel field, the expert has carried out a large amount of experimental studies both at home and abroad, has obtained certain achievement in research.The local standard of being correlated with of also having put into effect in succession of country.For example GB/T23510-2009 " vehicle fuel methyl alcohol ", GB/T23799-2009 " Vehicular methanol petrol (M85) ", GB18350-2001 " denatured fuel ethanol ", GB18351-2001 " vehicle-use alcohol gasoline " national standard are put into effect, and " Vehicular methanol petrol (M15) " also will put into effect; Simultaneously, large quantities of region standards of Shanxi Province, the relevant methanol gasoline in Shaanxi Province are also implemented.
The methanol gasoline aspect is applied mainly contains M5 ~ M15, M25 ~ M30, M85, M100.Low ratio methanol gasoline, below M30, petrol engine is not done any change, does not increase cost, is convenient to promote the use of.Its cold startability and accelerating ability and gasoline car be obviously difference not, and dynamic property slightly increases, and fuel consumption is suitable substantially, and discharging has certain improvement.In ratio methanol gasoline, as M30 ~ M70, petrol engine only need be done suitable adjustment, technology is simple, and startability, accelerating ability, dynamic property, fuel consumption compare with former petrol motor and increase by 8% ~ 10%, discharging improves more obvious.Gasoline of high proportion methanol, for example M85, M100, petrol engine will be installed automobile flexible fuel controller or reequip optimization (as adopting stainless steel fuel tank, fuel transfer system adopts the material of anti-methyl alcohol corrosion and swelling etc.).Its power and thermo-efficiency all are better than former petrol motor, and it is obvious that discharging improves effect.
But in the methanol gasoline of above-mentioned popularization, with respect to ethanol, methyl alcohol is not easy with gasoline miscible.In order to allow methyl alcohol and gasoline form more stable mixing solutions, and reach desirable effect, methanol gasoline must add and adds the desired additive of present technique.And the price of additive is generally all than higher.
The present invention is vehicle methanol fuel additive at high proportion, methyl alcohol, gasoline is mixed with certain proportion as the core technology material with this additive, forms automobile-used two pure gasoline clean fuel.Purpose is as follows:
The physico-chemical property of various fuel and fuel characteristic difference mix with learning from other's strong points to offset one's weaknesses.
Improve the stability of propellant combination, improve the stability of system, reduce the stratification temperature of system.
The source of methyl alcohol is abundant can to remedy the shortcoming that ethanol is subjected to the starting material restriction.
Summary of the invention
The object of the present invention is to provide a kind of vehicle methanol fuel additive at high proportion.
For achieving the above object, a kind of vehicle methanol fuel additive at high proportion of the present invention, it is characterized in that: mixed by following components in percentage by volume: gasoline 0～15%, vehicle fuel methyl alcohol 85～99%, vehicle methanol fuel additive TP 0.5～2.0% at high proportion; The described TP of vehicle methanol fuel additive at high proportion is made up of six kinds of different materials, and its proportioning step constitutes T1 according to ethanol+ethyltoluene; Isopropylcarbinol+primary isoamyl alcohol constitutes T2; Ether+120
#Solvent oil constitutes T3; T1, T2, T3 utilize static mixer three tunnel on-line mixing to form vehicle methanol fuel additive TP at high proportion.
The described TP of vehicle methanol fuel additive at high proportion, its proportioning is calculated with volume percent, and ratio is in low ratio, middle ratio, carry out proportioning at high proportion:
A kind of vehicle methanol fuel additive at high proportion of the present invention, its beneficial effect is: fuel of the present invention is selected the propellant combination of two alcohol+gasoline+additive for use; In use methyl alcohol and ethanol is at the complementary function of burning, aspect such as fused, and under moisture situation, the compatibility of ethanol and gasoline is also good than methyl alcohol, and ethanol the same with higher alcohols also be a kind of additive of methanol gasoline mixed fuel; Dynamic performance is strong, and pollutant discharge amount reduces.
