High heat sink jet fuels. 2. Stabilization of a JP-8 with model refined chemical oil/light cycle oil (RCO/LCO)-derived stabilizers

JP-900 is the generic name given to a future jet fuel that will be required to handle an anticipated thermal stress of similar to 900 degrees F (482 degrees C) for several hours. We report flowing rig scouting results, under approximate JP-900 conditions, examining the effect on both oxidative and pyrolytic stability of the addition of a few volume percent of model refined chemical oil/light cycle oil (RCO/LCO)-derived compounds to a petroleum-derived JP-8. Tetralin, tetralone, and tetralol were used as model hydroaromatic compounds, which, in principle, can be obtained via the hydrotreatment of RCO/LCO blends. Our scouting results suggest that a jet fuel with improved heat sink capabilities could likely be formulated by adding 1% v/v of hydroaromatic compounds to JP-8.
