Book Description
The investigation was concerned with the contribution of selected components and additives of high-temperature aircraft fuels to thermally induced deposits before and after 52 weeks storage at 130F. Of particular concern is the influence of these fuel constituents on thermal stability quality of these jet fuels during storage. The study utilizes a microfuel coker test apparatus to measure the thermal stability of test fuels and blends. The contribution of selected fuel components, labeled with carbon-14, to deposit-forming mechanisms is determined by radioactive counting techniques. Twenty-eight blends of the five test fuels with carbon-14-labeled fuel additives or components reached the final stage of storage at 130F and received final analyses for deposit forming tendency. These additives included an amine-type antioxidant, a metal deactivator, and a corrosion inhibitor. Also included in this study group were oleic acid and 1,5-hexadiene. All three additives showed a great tendency to degrade and react during storage and thermal stress. It was found that oleic acid interacts with cadmium present in aircraft fuel systems to produce deleterious effects upon the thermal stability quality of the fuel. Results showed changes in thermal stability quality of many of these blends containing sulfur compounds. Four additional special studies were conducted as preliminary investigations to continued research of jet fuel stability characteristics.
