Abstract: The effect of antioxidant, metal passivator, DSI ashless dispersant and their combination on the high-temperature thermal stability of aviation fuel was studied by the static and dynamic thermal oxidation stability tests, and their antioxidation mechanism was discussed. The results showed that the high-temperature thermal stability of aviation fuel could be significantly improved by the combination of DSI ashless dispersant (disuccinimide) with antioxidant and metal passivator. Furthermore, with the increase of disuccinimide content in the combination the thermal stability of aviation fuel was increased.
