Insight into the Mechanisms of Middle Distillate Fuel Oxidative Degradation. Part 3: Hydrocarbon Stabilizers to Improve Jet Fuel Thermal Oxidative Stability

Data is presented from the PSU flowing reactor in the 350−550 °C range that shows that jet fuel derived tube surface thermal oxidative deposit and temperature are inversely related; as fuel temperature increases tube surface deposit decreases. It is proposed that this phenomenon is due to a change i...

Description
Summary:Data is presented from the PSU flowing reactor in the 350−550 °C range that shows that jet fuel derived tube surface thermal oxidative deposit and temperature are inversely related; as fuel temperature increases tube surface deposit decreases. It is proposed that this phenomenon is due to a change in the relative rates of the steps for the peroxyl-radical-chain mechanism of autoxidation under conditions of very high radical initiation rates. In addition, data is presented for two novel hydrocarbon stabilizers, in five different fuels, which documents a 57% decrease, on average, for fuel thermal oxidative surface deposition.
