Abstract : Through the generally accepted 43 C and 65 C bottle storage method of accelerated aging, the relative ratings of six selected fuels' oxidative tendencies were established. In the 43 C test, storage for about 12 weeks produces results that are comparable to a full year's storage under ambient conditions. To develop a practical test method for the prediction of peroxide potential of fuels, experimental conditions were sought so that the oxidative tendencies of fuels could be assessed within a reasonable time. Accordingly, a matrix of experiments was designed to allow selection of reaction conditionally, the results of experiments should allow the development of global reaction kinetics to aid the determination of fuel peroxidation potential and to shed light on the reaction mechanism. The oxidations were carried out in a stirred pressurized reactor at 60, 80, 100, and 120 C, under oxygen pressures of 240, 790, or 1140 kPa (abs) for periods of up to 70 hours. Keywords: Turbine fuels, Peroxides, Oxidation, Potential peroxide content, Fuel storage, Accelerated fuel aging.
