Endothermic Reaction of High Heat Sink Hydrocarbon Jet Fuel

Hypersonic vehicle is not only the significant development direction in the field of air and space, but also the important symbol of the overall scientific and technological strength of a country. In order to combine cooling and propulsion functions, endothermic hydrocarbon fuel need to possess the basic characteristics of high heat sink, high density, high calorific value, high thermal stability, low freezing point, low coking and low cost. In this paper, the research progress of endothermic reactions of endothermic hydrocarbon fuels was summarized. This paper focusing on the effects of thermal cracking, catalytic cracking and catalytic steam reforming on heat sink. Firstly, the effects of pyrolysis conditions such as temperature, pressure and residence time on heat sink were analyzed. And then, the correlation between fuel composition, molecular structure and thermal cracking, and the effects of molecular sieves, nanoparticles and initiators on the catalytic cracking behavior and heat sink of endothermic hydrocarbon fuels were summarized. Furthermore, the influence of molecular sieve, nanoparticles and initiator on the catalytic cracking behavior and heat sink of endothermic hydrocarbon fuels, and the coking and inhibition technology in the process of endothermic reaction is summarized. Finally, the future research directions of endothermic hydrocarbon fuels are proposed in the light of the current development
