“…Both antioxidants extend the induction time, but the final oxidation rate remains the same. Zabarnick and Whitacre observed similar behavior for BHT in a fast oxidizing fuel stressed in the QCM . They showed that BHT slowed the oxidation rate until it was consumed, then the autoxidation continued at a more rapid rate.…”

An isothermal oxidation apparatus (IOA) has been modified to include an oxygen sensor so that both oxidation and deposition data can be measured for jet fuels that are thermally stressed. This modification is useful for comparing the relative oxidation rates of jet fuels and fuels blended with additives. Antioxidants can be evaluated in this apparatus by comparing the delay in the onset of oxidation at a given temperature in a fast oxidizing fuel. Other additive types, such as dispersants, can be evaluated by their ability to reduce deposition.

“…The initial slow oxidation during the first 10 h is due to the interception of alkylperoxy radicals by BHT. Previous work in our laboratory has shown that the subsequent rapid oxidation, which occurs here at 10 h, is due to the consumption of BHT below some critical concentration . The most striking observation from Figure is the extremely slow oxidation which occurs when both BHT and hexyl sulfide are present.…”

“…Fuel oxidation and deposition characteristics were evaluated in the quartz crystal microbalance (QCM) Parr bomb system that has been described in detail previously. , Most fuel oxidation tests were run at 140 °C and 1 atm of air initial pressure. The reactor is heated with a clamp-on band heater, and its temperature is controlled by a PID controller via a thermocouple immersed in the fuel.…”

“…Previous work in our laboratory has shown that the subsequent rapid oxidation, which occurs here at 10 h, is due to the consumption of BHT below some critical concentration. 4 The most striking observation from Figure 3 is the extremely slow oxidation which occurs when both BHT and hexyl sulfide are present. This run was extended beyond the normal 15 h period.…”

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 °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.

“…Various hindered phenol and amine antioxidants were evaluated. 6 We studied various aspects of jet fuel oxidation behavior, including the correlation between oxidation and deposition, the temperature dependence of oxidation and deposition, and studies of peroxy radical intercepting antioxidants and metal deactivator additives (Zabarnick and Whitacre, 1998). These studies showed a strong correlation between oxygen consumption and deposition, demonstrating the direct relationship between these phenomena.…”
