Hydrogenated jet fuel is saturated with olefins, so isn’t its stability improved? Why is it necessary to add antioxidants compulsorily, and why must they be added before entering the tank? 91-091 and AFQRJOS both have this requirement. Please clarify

S and N are antioxidants in themselves; theoretically, the oxidation stability of the oil after hydrogenation decreases

Increase the stability of aviation fuel to prevent oxidation

This is because the sulfur content required for aviation fuel in domestic markets is very low, yet sulfur possesses certain antioxidant properties. Therefore, antioxidants must be added to maintain the stability of aviation fuel.
