The effect of reactive sulfur removal from a Jet A-1 fuel with marginal thermal 3 stability on surface deposition propensity is reported. The sulfur removal was achieved 4 through adsorptive treatment the fuel with activated carbon.The treated fuel was as- 5 sessed for surface deposition propensity using a High Reynolds Thermal Stability(HiReTS)test 6 device. It was found that activated carbon has a strong adsorption capacity for removal 7 of reactive sulfur and Fe components from the fuel. This resulted in a substantial re- 8 duction of surface deposition propensity of the Jet A-1 fuel. 9 Density Functional Theory(DFT) was used to investigate the role of reactive sulfur and 10 Fe on thermal oxidative stability.Mechanistic pathways for intervention of these class 11 of species with hydroperoxides are proposed.
