Abstract
The application relates to a methanol fuel additive and a preparation method thereof, wherein the methanol fuel additive comprises the following raw materials in parts by weight: corrosion inhibitors: 7-30 parts of a solvent; lubricant: 10-60 parts; cleaning dispersant: 20-50 parts of a solvent; antioxidant: 5-20 parts of a solvent; solvent: 10-40 parts; wherein the corrosion inhibitor comprises benzotriazole, methyl benzotriazole and ammonium benzoate; the lubricant comprises dimer acid; the detergent dispersant comprises alkylphenol polyoxypropylene ether amine. The benzotriazole and the tolyltriazole are used as main components of a corrosion inhibitor, so that the corrosion inhibition effect on metals such as tin, copper and the like can be improved, and the addition of the ammonium benzoate can play a synergistic effect and further increase the corrosion inhibition effect on the metals. Because carboxyl molecules have strong polarity, dimer acid is used as a lubricant, a firm film can be formed on the surface of metal, and the friction coefficient of the metal is reduced. The alkylphenol polyoxypropylene ether amine is used as a detergent dispersant, and carbon deposition generated at an air inlet manifold, an oil sprayer and a cylinder piston can be reduced.
Description
Technical Field
The application relates to the technical field of fuels, in particular to a methanol fuel additive and a preparation method thereof.
Background
With the rapid development and the continuous increase of the industrialization speed of domestic economy, China has become the second largest petroleum consuming country in the world, and the consumption of petroleum tends to increase year by year. China is a large petroleum production country, but the relative shortage of petroleum is a non-competitive fact, the oil extraction and storage ratio of domestic oil fields declines year by year, and the production and supply of petroleum are far from meeting the increasingly expanding consumption demand. The proportion of crude oil imported in China in 2019 is up to 71%, which is far more than 30% of the internationally recognized safety warning line.
In China, the consumption of petroleum for automobiles accounts for more than half of the total consumption of petroleum, and the safety risk of petroleum is continuously increased due to the continuous temperature rise of the automobile market. According to the development process of the international automobile industry and the current state analysis of China, the proportion of automobile gasoline and diesel oil consumption in the total consumption of petroleum is greatly increased. Meanwhile, air pollution caused by oil consumption in vehicles is also becoming an increasingly serious social problem. This fully indicates that our country is facing increasingly severe pressure on petroleum safety, environmental protection, and the like.
Diversification of vehicle energy is a necessary way. The government of China pays attention to the development of novel, clean and alternative energy. The methanol fuel has wide application prospect as a novel automobile power energy source, has the advantages of high octane number, good cleanness, low cost, renewability and the like compared with the traditional fuel gasoline, and is an important gasoline substitute energy source.
The methanol fuel is a novel clean fuel prepared by strictly scientific process blending and a series of fine processing according to a certain volume (or weight ratio) by utilizing industrial methanol or fuel methanol and a denatured alcohol additive and the existing national standard gasoline and diesel oil (or component oil). The methanol fuel is divided into methanol gasoline and methanol diesel, namely, the methanol gasoline and the methanol diesel are prepared by methanol, gasoline/diesel and an additive according to a certain volume. The prepared methanol fuel has different types, such as M15, M20, M30, M85, M100 and the like, and is used for expressing the proportion of methanol in the finished methanol gasoline/diesel oil. The M100 methanol fuel is prepared by mixing 99% of refined methanol and an additive, and has more obvious advantages in the aspects of environmental protection, energy conservation, resource utilization rate improvement and the like compared with the methanol fuel with lower proportion.
However, methanol is easily oxidized by oxygen in the air during production, storage, transportation and use to generate a small amount of formic acid, and the methanol also has very high water absorption property, and the substances are easy to corrode metals such as copper, iron, zinc, tin and the like; and the lubricity of methanol is poorer than that of gasoline, and alcohol-related movable parts in an oil way are easy to wear, so that the service life of parts can be greatly reduced.
