Abstract

The invention belongs to the technical field of liquid fuel, and more specifically relates to a high-energy alcohol-based fuel additive for military use and a preparation method thereof. The additivecomprises the following raw materials in parts by weight: 5-10 parts of ethanol, 3-5 parts of triacetin, 4-7 parts of a cation fluorocarbon surfactant, 1-4 parts of ferric nitrate, 10-15 parts of a hydrocarbon compound, 10-15 parts of a combustion improver, 3-5 parts of a stabilizing agent, 3-5 parts of an anti-knock agent, and 1-4 parts of a deodorant. The composite additive can be added into thealcohol-based fuel, in order to substantially improve calorific value of the fuel, ensure fully and thoroughly combustion without generation of carbon deposition phenomenon, and improve corrosion resistance and stability of the fuel.

Description

technical field [0001] The invention belongs to the technical field of liquid fuels, and in particular relates to a military high-energy alcohol-based fuel additive and a preparation method thereof. Background technique [0002] Alcohol-based fuel is a clean fuel with the advantages of sanitation, safety and environmental protection, convenient use, and low cost. It is the most potential new alternative renewable resource in the future. However, the alcohol-based fuels in the existing technology have the following disadvantages when used: low combustion calorific value and low power; unstable, not conducive to transportation, and prone to knocking; water and sediment generated by combustion are corrosive, and long-term use It will seriously affect the service life of combustion equipment. Therefore, it is of great significance to study an additive that can improve the above-mentioned shortcomings of alcohol-based fuels. Contents of the invention [0003] The technical pr...
