Improved thermal stability of paraffinic jet fuels using oxygen substituted hydrogen donors in the autoxidative and pyrolytic regimes

The use of oxygenated hydrogen donors, e.g., α-tetralone, considerably increased the thermal stability of n-tetradecane that was used as a model compound for jet fuel. The model compound for paraffinic jet fuels studies was n-tetradecane and the jet fuel studied was JP-8. The mixture of the hydrogen donors α-tetralone and tetralin suppressed the formation of formation of aromatic compounds during stressing of JP-8, particularly 3 and 4 ring aromatics. The use of α-tetralone and tetralin reduced both the autoxidative and pyrolytic deposition from the JP-8 jet fuel.
