Description

A kind of high efficiency methanol fuel additive for diesel engine
Technical field
The present invention relates to diesel fuel technical field is and in particular to a kind of high efficiency methanol fuel for diesel engine adds Agent.
Background technology
Crude oil is global topmost primary energy, and the essence of current energy source shortage is crude oil shortage.Vehicle fuel is former The topmost application of oil, accounts for more than the 70% of global crude oil total flow.Up to the present, the oil of China is externally interdependent Degree has exceeded 50%.And the reserves position of China's coal is at the forefront in the world, with coal petroleum replacing be reduce China oil externally interdependent The desirable route of degree.
The mixture methanol fuel of methanol and diesel oil is a kind of " with coal for replacing oil " path.Methanol fuel is using industry Methanol or fuel methanol, a kind of Novel clean made through the allotment of strict scientific technology by certain weight ratio with existing GB diesel oil Fuel, can partially or completely diesel oil substitute, for diesel engine motor vehicles.The raw material producing methanol is mainly coal, natural gas, Coal bed gas, oven gas etc., produce methanol in particular with high-sulfur colm and oven gas, not only can improve comprehensive utilization of resources but also can Reduce environmental pollution.And rich coal resources in China, Development of Coal methanol fuel, supplement and part petroleum replacing fuel, be slow Solution China energy shortage situation, improves comprehensive utilization of resources, preserve the ecological environment a effective way.
Methanol is to add additive in methanol and be added without diesel oil as another approach of diesel fuel, such as China Patent documentation CN 101486940A, CN 1403543A and CN 1257110A.There is following technological deficiency in it：Bavin at low temperature Oil start is relatively difficult, is not suitable for the winter of north cold；Long-time placement can be separated, especially the sky of humidity Gas or containing water when be easier occur be separated.Authorization Notice No. is that the Chinese patent of CN102746906B discloses a kind of bavin The oil machine additive of high efficiency methanol fuel, by crown ether, ketone, amide, alkyd, ortho esters, azo-compound and 8- nitro isoquinoline Quinoline forms, and each component weight proportion is as follows：Crown ether 30～65 weight portion, ketone 10～20 weight portion, amide 5～20 weight portion, alcohol Sour 20～45 weight portions, ortho esters 17～36 weight portion, azo-compound 8～21 weight portion, 8- nitroisoquinoline 13～19 weight Amount part.Practical application finds, the additive long-time storage of above-mentioned high-proportion methanol fuel still suffers from a certain degree of phase and divides From cold-starting effect is still undesirable.
