Abstract

The invention belongs to the technical field of military fuels, concretely relates to a military fuel mainly using petroleum coke as a raw material, and also relates to a preparation method of the fuel. The military fuel mainly using the petroleum coke as the raw material includes the petroleum coke, C12-C20 bicyclic alkene and C8-C24 alkyne, wherein a mass ratio of the petroleum coke to the C12-C20 bicyclic alkene to the C8-C24 alkyne is 12:5:8. The military fuel obtained by the method can be used by aviation aircrafts, or can be added to military fuels as a fuel additive, contains 1.04 g/cm<3> of C16, and can effectively improve the carrying energy of the aircrafts, reduce the fuel consumption of engines and meet large-voyage, high-speed and long-range requirements.

Description

technical field [0001] The invention belongs to the technical field of military fuel, and in particular relates to a military fuel mainly using petroleum coke as a raw material, and also relates to a preparation method of the above-mentioned fuel. Background technique [0002] Aviation fuel includes aviation gasoline for ignition piston engines and jet fuel (commonly known as aviation kerosene) for gas turbine engines. Mainly obtained by petroleum processing. A common requirement for all aviation fuel compositions is that they should be pure hydrocarbon mixtures containing only proprietary additives. However, due to the different properties of different hydrocarbons, there are certain restrictions on the content of certain hydrocarbons such as aromatic hydrocarbons and olefins. The non-hydrocarbons remaining in the fuel, such as: oxygen-containing, sulfur-containing, nitrogen-containing and other heteroorganic compounds and their combustion products, not only cause corro...
