Description

technical field [0001] The invention relates to the field of alcohol substitute fuels, in particular to a bioalcohol-based fuel solubilizer. Background technique [0002] Alcohol fuel, as a clean, cheap and efficient alternative to fossil fuels, has been valued for its abundant sources and is considered to be the most promising substitute fuel for fossil fuels. George A. Ola, the winner of the Nobel Prize in Chemistry in the United States, believes after long-term research that "methanol economy" makes human beings no longer depend on the dwindling oil and natural gas as alternative fuels, and the development prospects in our country are gradually becoming clear. The boiling point of methanol is lower than that of diesel, and the formation of mixed gas is faster and more uniform, which is conducive to complete combustion; the oxygen content of methanol accounts for 50%, its ignition limit is wider than that of diesel, and its combustion speed is higher, which is conducive to...

AI Technical Summary

Problems solved by technology

[0003] (1) Methanol and diesel are difficult to dissolve in each other. One is that the number of carbon chains between the two is too different, 1:10-22. Second, because methanol contains hydroxyl groups, it is a polar substance. Diesel is non-polar, and the mutual solubility between solutions always follows The "principle of similar miscibility of mixed solutions" leads to the solution of the mutual solubility of methanol and diesel oil, which is a recognized bottleneck problem; therefore, it is difficult to mix methanol and diesel oil, no matter relying on pressure mixing or adding a certain amount of co-solvent. Ensure the uniform mixing of methanol and diesel oil, the mixed fuel is easy to stratify, and the stability is poor;

[0004] (2) The ignition point of methanol is as high as 470°C, which is much higher than the ignition point of diesel oil at 200-220°C. Therefore, methanol is difficult to compress and ignite, and its ability to spontaneously ignite is relatively poor;

[0005] (3) The latent heat of vaporization of methanol is large, and the cooling effect produced by the high latent heat of vaporization will have an adverse effect on the working conditions of the engine at low speed and low load;

[0006] (4) The viscosity of methanol is low. When the original fuel injection system of the diesel engine is directly used, it will cause system wear and even jamming, which will affect the reliability and durability of the engine.

The patent number is CN1908130A, which discloses a "cleaning and standard-increasing emulsifier for methanol and diesel for vehicles" and the patent number is CN101323802A, which discloses a "stabilizing and synergistic additive for methanol and diesel for vehicles", and its dosage is 15-20 of the finished product. %, 10-15%, the dosage is very large and the cost is very high; the patent number is CN102161922A, which discloses a "methanol diesel additive and methanol diesel", which uses acetone and toluene, which are toxic and have a very low flash point, and the additive dosage >10%; the patent number is CN102229820A, which discloses a "denatured methanol diesel and its blending process", which uses polymethoxymethyl ether, which is actually a polymer of methylal, which is explicitly prohibited from being added to diesel The substance; the patent number is CN101709234A, which discloses a "methanol diesel composite additive and its preparation method", which uses dihexadecyldimethyl ammonium chloride with very good electrical conductivity, which can be completely ionized in methanol, Forms an electrolyte, which has a very high electrical conductivity and thus accelerates the corrosion of the oil system

Due to the high price of co-solvent and accelerator, and the large amount of use, it limits its promotion and use in market fuels
