In this study we explore the use of silylation agents as jet fuel additives for reducing oxidative deposition. Silylation agents have the ability to react with the heteroatomic species, such as phenols, which have been implicated in deposit-producing mechanisms. Thus, they have the potential to chemically transform these species into relatively innocuous silylated products. In this work we study the effect that silylation agents have on jet fuel oxidation and deposition. We show that these additives result in an increased oxidation rate and substantially reduced deposition. The increased oxidation rate is due to the removal of these heteroatomic species which can act as antioxidants by intercepting peroxy radicals. The results show that silylation agents may be useful as jet fuel additives for preventing oxidative deposition in advanced aircraft fuel systems, including endothermic fuel systems. Silylation agents have also been proven to be useful in identifying fuel components, particularly those detrimental to fuel thermal stability.
