We have explored the use of hydroperoxide decomposing species for inhibiting oxidation in jet fuel. We find that hydroperoxide decomposing species, such as alkyl sulfides, do not slow or delay oxidation in hydrocarbon solvents at 140 degrees C. However, when phenolic species are also present, such as those naturally occurring in fuel or by addition of hindered phenols, substantial delays in oxidation are observed. We used a pseudo-detailed chemical kinetic mechanism to provide insight into the oxidation process. The combination of hydroperoxide decomposer and hindered phenol can substantially inhibit oxidation of fuel under the conditions studied here.
