Embodiment 1

[0030] Take by weighing a certain amount of triethylamine and borane according to the ratio of equimolar nitrogen and boron, put triethylamine into the container, then add borane, and fully stir to form 10% triethylamine ( A) Borane, configure 30% hexamethylenediamine borane complex, 40% tripropylamine triethylborane complex, 10% tributylamine (a) borane, tri-n-octyl Amine (a) borane 10%;

[0031] Then the solutions of the five configurations were poured into the reactor one by one and fully stirred and mixed to form the final liquid fuel.

[0032] This kind of liquid fuel is mainly used for heat flux density greater than 3.5MW / m 2 , Endothermic fuel for engines under the supercritical condition of the heat exchange environment temperature of 500℃~1100℃.

Embodiment 2

[0034] According to the requirement of equimolar nitrogen and boron ratio, take a certain amount of tri-n-octylamine and put it into a container, add borane, fully stir to form tri-n-octylamine-borane complex, and set aside;

[0035] Put 99.89% hydrotreated light distillate oil into the reaction kettle, and pass it into dry nitrogen protection;

[0036] Then take 0.01% of the previously configured tri-n-octylamine borane complex and pour it into the reaction kettle to fully stir and mix;

[0037] Finally, 0.1% triethylaluminum is gradually added dropwise and fully stirred to form the final liquid fuel.

[0038] This kind of liquid fuel is mainly used for heat flux density less than 3.6MW / m 2 , Endothermic fuel for engines under the supercritical condition of the heat exchange environment temperature of 500℃~750℃.

Embodiment 3

[0040] According to the requirements of equimolar nitrogen and boron ratio, weigh a certain amount of tri-n-octylamine and put it into a container, add borane, stir fully to form a tri-n-octylamine-borane complex, and configure adipic diethylamine in the same way Amine borane complex, tripropylamine triethylborane complex, tributylamine (a) borane complex, standby;

[0041] Put 0.05% hydrotreated light distillate oil into the reaction kettle, and pass through dry nitrogen protection;

[0042] Take 20% tri-n-octylamine borane complex, 29.94% hexamethylenediamine diborane complex, 20% tripropylamine triethylborane complex, 30% tributylamine (methyl) boron Alkane complexes are poured into the reaction kettle in portions and fully stirred and mixed;

[0043] Finally, 0.01% triethylaluminum is gradually added dropwise and fully stirred to form the final liquid fuel.

[0044] This kind of liquid fuel is mainly used for heat flux density less than 3.6MW / m 2 , Endothermic fuel for ...

Abstract

The invention relates to a liquid fuel and a preparation method thereof. The liquid fuel is prepared by completely stirring the complex of alkylamine and alkyl borane, which serves as a main raw material, and hydrogenated light distillate and aluminum ethyl, which serve as auxiliary materials, under the normal temperature and the normal pressure. The liquid fuel has the characteristics of high heat sink, more pyrolysis products, high eneyne hydrocarbon product selectivity, low coking rate, particular suitability for heat transfer under the supercritical condition of 500 to 1,100 DEG C, simple preparation method and the like. The combustion product of the preparation method does not contain any toxic and harmful substance and meets the environmental requirement.

Description

technical field [0001] The invention relates to a fuel and a preparation method thereof, in particular to a liquid endothermic fuel and a preparation method thereof. Background technique [0002] In terms of liquid fuels, petroleum distillates are mostly used at home and abroad, which are modified by hydrotreating to form endothermic hydrocarbon fuels, such as RP-3. However, due to the complex composition of these liquid fuels, which contain relatively high aromatics and naphthenes, the amount of fuel cracking and coking during use is large, the available heat sink is low, and the selectivity of cracking products is low. The cooling and heat exchange requirements of the heat flow environment make it difficult for existing liquid fuels to meet the heat exchange requirements under supercritical conditions of 500°C to 1100°C. Contents of the invention [0003] The object of the present invention is to provide a liquid fuel and a preparation method thereof in order to overcom...
