This paper presents research that supports a proposed fuel oxidation/deposition mechanism involving acid:base reactions between “oxidizable” sulfur compounds, “basic” nitrogen compounds, and oxygen-containing polymers. The reported research presents experiments that study the effects of different sulfur compounds on the high-temperature (160–220°C) oxidation products and deposition tendencies of jet fuel. Surface analyses incorporating elemental analyses and depth profiles of deposits formed on steel surfaces were performed to identify the species involved in the initial stages of deposition by jet fuels. Experiments to study the effects of acid neutralizing compounds on the deposition tendencies of jet fuels are also presented.
