Description

Technical Field

[0001] The invention relates to the field of fuel technology, in particular to a high-energy liquid fuel containing a transition metal organic complex and a preparation method thereof. Background Art

[0002] High-energy liquid fuel is a liquid fuel with development prospects. Its detonation energy is much higher than the energy released by the same mass of explosives. It is mainly achieved by scattering the fuel into the air, atomizing the fuel droplets and fully mixing with the air to form a cloud, and then using a secondary fuse to implement strong initiation, detonating the cloud containing the fuel droplets, and using high temperature, high pressure and strong shock waves to destroy the target; and the shock waves are reflected and superimposed between the walls, and the overpressure value is much higher than that in open spaces.

[0003] At present, the common high-energy liquid fuel formula is mainly ethylene oxide, propylene oxide, alkanes, alkenes or bridged ring compounds, and the sensitizer is mostly nitrate nitro compounds such as isopropyl nitrate and isobutyl nitrate or nitromethane. In order to increase the temperature during detonation and enhance its killing ability against soft targets, the existing technology generally adds aluminum powder to the fuel to increase the detonation temperature, but the metal aluminum powder will settle during storage, which greatly affects the stability of the high-energy liquid fuel during storage and use. Summary of the invention

[0004] In view of this, the object of the present invention is to provide a high-energy liquid fuel containing a transition metal organic complex. The high-energy liquid fuel provided by the present invention has excellent stability and combustion performance.

[0005] The present invention provides a high-energy liquid fuel containing a transition metal organic complex, comprising the following components in percentage:

[0006] 20-40wt% main fuel;

[0007] 10-15wt% chain ether;

[0008] 20-30wt% cyclic ether;

[0009] 15-50 wt% of a transition metal organic complex, wherein the transition metal organic complex comprises one or more of a transition metal carbonyl compound and a transition metal carbonyl hydride.

[0010] Preferably, the metal in the transition metal organic complex includes one or more of Group VB, Group VIB, Group VIIB and Group VIIIB metal elements.

[0011] Preferably, the transition metal organic complex is one or more of vanadium hexacarbonyl, chromium hexacarbonyl, molybdenum hexacarbonyl, tungsten hexacarbonyl, manganese decacarbonyl, iron pentacarbonyl, iron nonacarbonyl, iron triazone, cobalt octacarbonyl, tetracobalt dodecacarbonyl, nickel tetracarbonyl, manganese pentacarbonyl hydride, cobalt tetracarbonyl hydride and iron tetracarbonyl dihydride.

[0012] Preferably, the main fuel includes one or more of normal alkanes with a carbon number not exceeding 12, isoalkanes with a carbon number not exceeding 12, non-terminal olefins with a carbon number not exceeding 12, saturated hydrocarbons with a carbon number not exceeding 14 and containing a benzene ring, dispirocyclic hydrocarbons with a carbon number not exceeding 18, trispirocyclic hydrocarbons with a carbon number not exceeding 18, di-bridged cyclic hydrocarbons with a carbon number not exceeding 18, tri-bridged cyclic hydrocarbons with a carbon number not exceeding 18, tetra-bridged cyclic hydrocarbons with a carbon number not exceeding 18, and bridged and parallel cyclic hydrocarbons with a carbon number not exceeding 18.

[0013] Preferably, the main fuel is petroleum ether with a boiling range of 30-120°C.

[0014] Preferably, the chain ether includes one or more of saturated alkyl ether, aryl or arylalkyl ether and polymethoxydialkyl ether; the cyclic ether includes one or more of alkylene oxide, furan or substituted furan, pyran and substituted pyran.

[0015] Preferably, the chain ether includes one or more of methyl ethyl ether, ethyl ether, isopropyl ether, isobutyl ether, methyl tert-butyl ether, anisole and polymethoxydialkyl ether.

[0016] Preferably, the methoxyl polymerization degree of the polymethoxy dialkyl ether is 1-20.

[0017] Preferably, the alkyl group in the polymethoxydialkyl ether is one or two of a saturated normal alkane having 1 to 16 carbon atoms, an isoalkane having 3 to 16 carbon atoms, and an aromatic substituted alkyl group.

[0018] Preferably, the alkylene oxide includes one or more of ethylene oxide, methylethylene oxide, dimethylpropylene oxide, propylene oxide, 2-methylpropylene oxide, 3-methylpropylene oxide, 2,3-dimethylpropylene oxide and butylene oxide.

[0019] There are two main technologies for detonating high-energy liquid fuels: secondary detonation technology or primary detonation technology. For the secondary detonation technology, the first detonation is used to blow up the container and scatter the fuel, and the second detonation is used to ignite the fuel cloud to form a detonation. For the primary detonation technology, compared with the secondary detonation, the primary detonation is simpler and has lower costs. The characteristics of the primary detonation are that the shock wave generated by the external energy is used to synchronously induce the detonation of the fuel (such as electric sparks or detonators), or the fuel components themselves release heat to gradually induce the detonation of the fuel (such as chemical catalysis, photocatalysis or thermal turbulent jet initiation method, etc.). The present invention is a high-energy liquid fuel for the single detonation technology, and its detonation model is a combustion-to-detonation transition (DDT) model. After the fuel of the present invention generates a cloud, the transition metal organic complex component (represented by tetracarbonyl nickel and pentacarbonyl iron) in the fuel can quickly self-ignite in the air without catalysis, playing the role of self-induced detonation fuel. The present invention provides a scheme for inducing detonation by simply relying on the spontaneous reaction of fuel components without catalysis and physical induction.

[0020] The high-energy liquid fuel provided by the present invention provides detonation temperature with a transition metal organic complex, and the transition metal organic complex can be well dissolved in chain ethers and cyclic ethers, and has a long storage time in the liquid system formed by chain ethers and cyclic ethers, and can be stored for a long time without sedimentation, aggregation or deterioration under air-tight conditions, and has good storage stability; and the transition metal organic complex has lower detonation energy and higher combustion energy, which ensures the detonation temperature of the high-energy liquid fuel. Therefore, the high-energy liquid fuel provided by the present invention has a good balance between stability and combustion performance. BRIEF DESCRIPTION OF THE DRAWINGS
