Embodiment 1

[0042] Weigh HPG-C 16 (Number-average relative molecular mass: 1,000), stirred and dissolved in n-dodecane at 40°C to form a 0.01% solution. Measure the heat sink values ​​of n-dodecane and the above solutions at temperatures of 600, 630, 660, 690 and 720°C at 3.5MPa and 1g / s flow rate respectively. The results showed that the heat sink value of n-dodecane at these temperatures increased from 2140, 2210, 2520, 2910 and 3338 kJ / kg to 2160, 2240, 2650, 3022 and 3340 kJ / kg, respectively. The above solutions are suitable for immediate use.

Embodiment 2

[0044] Weigh HPG-C 16 (Number-average relative molecular mass: 3,200), dissolved in n-dodecane with stirring at 40°C to form a 0.1% solution. Measure the heat sink values ​​of n-dodecane and the above solutions at temperatures of 600, 630, 660, 690 and 720°C at 3.5MPa and 1g / s flow rate respectively. The results showed that the heat sink value of n-dodecane at these temperatures increased from 2140, 2210, 2520, 2910 and 3338 kJ / kg to 2225, 2372, 2792, 3206 and 3592 kJ / kg, respectively. The above solutions are suitable for immediate use.

Embodiment 3

[0046] Weigh HPG-C 16(Number-average molecular mass: 3,800), stirred and dissolved in n-tridecane at 40°C to form a 0.03% solution. Measure the heat sink values ​​of n-tridecane and the above solutions at temperatures of 600, 630, 660, 690 and 720°C at 3.5MPa and 1g / s flow rate respectively. The results showed that the heat sink value of n-tridecane increased from 2160, 2448, 2941, 3242 and 3600kJ / kg to 2210, 2536, 2970, 3296 and 3643kJ / kg at these temperatures, respectively. The above solutions are suitable for immediate use.

Abstract

The invention discloses a hydrocarbon fuel composition with high heat sink. The hydrocarbon fuel is composed of the following raw materials in weight percentage: 100% of a hydrocarbon fuel and 0.01%-5% of HPG-C16. The invention discloses a novel hydrocarbon fuel composition, HPG-C16 (cetyl grafted hyperbranched polyglycerol) is used as an initiator to promote the cracking degree of hydrocarbon fuel, enhance heat sink of the hydrocarbon fuel, improve the heat absorption capacity of the hydrocarbon fuel, and proposes a novel development direction for the application of HPG-C16.

Description

technical field [0001] The invention relates to the technical field of hydrocarbon fuels, in particular to a hydrocarbon fuel composition with high heat sink. Background technique [0002] The increase of the flight speed of the aircraft will inevitably cause the surface temperature of the skin and the engine to be too high, making the thermal management and cooling of the aircraft one of the key issues to be solved in the development of high-speed aircraft. The development of "combustible coolant" endothermic hydrocarbon fuel is an important way to solve this problem. The heat sink of this type of fuel comes from two aspects. On the one hand, it is a physical heat sink that uses the hydrocarbon fuel itself to heat up and absorb heat through phase change. A series of chemical heat sinks for polymerization reactions can absorb a large amount of heat generated by the flight system and crack it to produce small molecular products with excellent combustion performance. Combusti...
