Abstract

The invention provides a high-density composite liquid hydrocarbon fuel and a preparation method thereof, and application of an organic small molecule dispersant in the high-density composite liquid hydrocarbon fuel. The high-density composite liquid hydrocarbon fuel comprises the following raw materials in parts by mass: 100 parts of hanging type tetrahydrodicyclopentadiene, 0.09 to 0.5 part of adiureido organic small molecule dispersing agent and 5-43 parts of a high-energy solid fuel. The preparation method comprises the following steps: adding the diureido organic small molecule dispersing agent into the hanging type tetrahydrodicyclopentadiene, and carrying out heating to 110-130 DEG C for dissolving; then performing cooling to 10-35 DEG C, and conducting standing for 1-3 hours; andadding the high-energy solid fuel in a stirring state to prepare the high-density composite liquid hydrocarbon fuel. According to the invention, the high-energy solid fuel is stably dispersed in the hanging type tetrahydrodicyclopentadiene of the high-density hydrocarbon fuel through a supramolecular self-assembly process of diureido organic small molecules, so the density and the energy level ofthe hanging type tetrahydrodicyclopentadiene high-density hydrocarbon fuel are improved.

Background technique [0002] Aircraft power source is the basic research field of aerospace technology, and its power is directly related to the range, speed and load of the aircraft. With the development of various aircraft, higher and higher requirements are placed on fuel. High-density fuel can provide more energy without increasing the size of the fuel tank, and is an important fuel for rapidly improving flight performance at low cost. However, the freezing point and viscosity of synthetic high-density fuel increase sharply with the increase of density. Using chemical The method of synthesizing new fuel molecular structures has been difficult to greatly increase the energy density of liquid fuels, and new app...
