Problems solved by technology

[0004] In the prior art, the alcohols used by most small manufacturers for alcohol-based fuels are cheap recycled methanol and ethanol, which are relatively cheap, but the recovered alcohols have many impurities and require multiple processes such as rectification and filtration to ensure Product quality, inseparable substances greatly affect the combustion quality of fuel, and in the process of preparing alcohol-based fuel, a large amount of alcohol needs to be added to meet the national standard of alcohol-based fuel
Moreover, for alcohol-based fuels, under the premise of ensuring the combustion value, the greater the amount of alcohol added, the better. However, when the amount of alcohol added increases, the flash point of the alcohol-based fuel becomes lower, and the flash point is 12. ~18°C, forming an extremely flammable alcohol-based fuel, which greatly reduces the safety factor in the process of transportation and storage

Abstract

The invention relates to the field of fuels, and discloses a high-performance alcohol-based fuel, which is prepared from the following raw materials in parts by weight: 70-85 parts of an alcohol, 5-10parts of a surfactant and 10-20 parts of water. According to the invention, the hydroxypropyl methyl cellulose in the surfactant performs modifying compounding on the alcohol-based fuel, so that thealcohol solution is non-volatile and high in stability, the flash point and the combustion working condition of the fuel are improved, and the safety coefficient of storage and transportation environments is improved; and by using the low-carbon alcohol with high mass percentage content as the raw material, the secondary pollution after the fuel combustion is reduced.

Description

technical field [0001] The invention belongs to the field of fuel technology, and in particular relates to a high-performance alcohol-based fuel and a preparation method thereof. Background technique [0002] Alcohol-based fuel is a fuel mainly configured with alcohols such as methanol, ethanol, butanol and other substances. It exists in the form of liquid or solid, and it is also a kind of biomass energy. It is an environmentally friendly and clean energy that governments are vigorously promoting at present. [0003] Petroleum-based fuels, whether it is gasoline or diesel oil, are distillates of petroleum hydrocarbons, which contain a considerable amount of aromatics and sulfides, and there are environmental pollution problems in fuel applications. At the same time, general hydrocarbons, because their composition basically does not contain oxygen, can easily cause incomplete combustion, and then cause volatile organic compounds (VOC) emissions, while alcohol-based fuels wi...
