Autoxidation kinetics is an important oxidation-stability index of endothermic hydrocarbon fuels. In this work, the autoxidation kinetics of lab-made No. 1 endothermic hydrocarbon fuel (EHF-1, with 25 ppm butylated hydroxytoluene (BHT)) was studied from two aspects of temperature and dissolved oxygen by accelerated oxidation. When the autoxidation kinetic equations are combined with the Arrhenius equation at different temperatures, it is estimated that the storage period of EHF-1 with air isolation at 20 degrees C is 12.5 years. BHT did not work for the autoxidation chain reaction at low concentration (<5 ppm), but the inhibition is not affected when the oxygen content was low (<50% saturation). In addition, the reaction rate of BHT with oxygen is faster than that of hydrocarbon with oxygen as temperature or oxygen content increases. The difference of reaction rate changed from 0.02 to 17.63 ppm.11-1 when the temperature rose from 70 to 150 degrees C and changed from 3.28 to 17.63 ppm.h(-1) when the oxygen content rose from 25% saturation to 100% saturation. Moreover, the inhibitory effect of BHT on fuel oxidation was still weaker than the promotion of oxygen. On the whole, the oxidation stability of fuels can significantly improve when the oxygen content is below 50% saturation.
