Description
Technical Field
The invention relates to the field of alcohol alternative fuels, in particular to a method for preparing a methanol gasoline additive by microbial fermentation of a illegal cooking oil product and application thereof.
Background
Since the birth of the first automobile in 1886, over 130 years, the fuel of various motor vehicles still mainly comprises gasoline and diesel oil, and the use mode is increasingly limited by serious environmental pollution and increasingly scarce resources. With the continuous progress of science and technology and the continuous development of alternative energy sources, a plurality of vehicle energy source alternative modes are greatly emerged, however, if the alternative modes are applied in a large scale, the alternative modes are all limited by factors of high cost, complex technology, unsound supporting facilities and the like; meanwhile, the exhaust emission of various motor vehicles contains a large amount of particulate matters and greenhouse effect gases, the particulates mainly comprise black carbon-containing substances, the sedimentation rate is low, the particulates can be suspended in the atmosphere for a long time, and severe haze is caused along with the emitted greenhouse effect gases, so that the harm to the health of human beings is great.
Alcohol fuel is regarded as the most promising vehicle fuel in the field of alternative fuels as a clean, cheap and efficient alternative to petrochemical fuel, and the low cost and abundant sources of the alcohol fuel are increasingly emphasized. Long-term research shows that the methanol economy is used as a substitute fuel, so that people can no longer depend on increasingly reduced petroleum and natural gas resources, and the situation is particularly in line with the increasingly short supply of petrochemical resources in China. The oxygen content of the methanol accounts for 50 percent, the ignition limit of the methanol is wider than that of gasoline, the combustion speed is high, and the emission of particulate matters is favorably reduced; the theoretical air-fuel ratio of the methanol is lower than that of gasoline, the combustion in an engine is more complete, and the emission of greenhouse effect gases can be effectively reduced. However, methanol as an alternative fuel for gasoline engines has the following disadvantages: (1) because the methanol contains hydroxyl and is a polar substance, the methanol and the gasoline are easy to generate the phenomenon of layering after being mixed, and the storage stability is poor; (2) the flash point of the methanol is as high as 12 ℃ and is much higher than that of gasoline at minus 45 ℃, so that the methanol is not easy to ignite in winter, the spontaneous ignition capability is poor, and the phenomenon of difficult cold start of a low-temperature vehicle is easy to occur; (3) the latent heat of vaporization of the methanol is large, and the cooling effect generated by the high latent heat of vaporization can generate adverse effect on the working conditions of the engine at low speed and low load; (4) the lubricity of methanol is poorer than that of gasoline, and when the original fuel injection system of a gasoline engine is directly used, the system is abraded, so that the reliability and the durability of the engine are influenced; (5) the saturated vapor pressure of the methanol is higher than that of gasoline, so that the phenomenon of high-temperature air resistance is easy to occur; (6) the theoretical lower heating value of methanol is only 46% of gasoline, so it is far less dynamic than gasoline. In addition, because the cleaning effect of the methanol is strong, the carbon deposit in the oil way system of the oil tank can be cleaned, and the filter screen and the oil nozzle of the oil pump are blocked.
In order to solve the above problems of the methanol fuel, many new patent technologies have been developed in recent years. The patent number is CN102660336A, which discloses a methanol gasoline cosolvent, wherein the cosolvent contains dimethylbenzene, belongs to benzene substances, and causes secondary pollution to the environmentHarming; the patent No. CN102643689A discloses a 'M85 methanol gasoline additive for vehicles and a preparation method and application thereof', wherein in the embodiment, the additive is 5 percent in dosage, the use cost is high, and the additive contains a large amount of aniline substances which are nitrogen-containing compounds and can generate NO after combustionXThe compound belongs to acid rain substances, and causes environmental pollution in the discharged air; the patent No. CN102041114A discloses a methanol gasoline composite additive, wherein an antioxidant in the methanol gasoline composite additive is zinc dialkyl dithiocarbamate, belongs to metal salt substances, and can initiate and accelerate the generation of electrochemical corrosion in the methanol gasoline, accelerate the corrosion of an oil pump wire of a vehicle and cause the damage of the vehicle; patent No. CN104726149A discloses a bio-based methanol gasoline composite additive and bio-based high-proportion methanol gasoline, which have thorough analysis on common problems of the methanol gasoline and detailed solutions, but are used in triethanolamine for preparing yeast fatty acid soap, contain NO compounds and are not beneficial to environmental protection and discharge. Therefore, the research and development of a novel environment-friendly methanol gasoline additive which is low in dosage, low in cost, good in effect, biodegradable, free of harmful components and electrolytes and free of secondary pollution to the environment is urgent.
