Abstract:
The reliability of a small-scale 5-ml Bomb, static thermal stability test procedure, based on optical measurements of fuel compositional changes induced by thermal stressing was established. Five aviation turbine fuels, covering a range in inherent thermal stabilities from 300F to 700F, were studied to determine the effect of storage duration in sealed drums at 40F ambient, 130F and 180F on their thermal stability quality. Four of the fuels, representing straight-run production fuels were not susceptible to deterioration at these storage temperatures through the storage periods investigated. A fifth fuel, synthetic HF alkylate, showed a maximum loss of about 100F at all storage temperatures except 40F. Susceptibility is attributed to its relatively high olefinic content about 2 volume per cent and the presence of possible reactive tertiary hydrogen components. Removal of dissolved oxygen to less than one part per million prior to storage prevented deterioration of the HF alkylate fuel and improved the thermal stability of the poorer quality fuels. Information was also obtained on the effects of various contaminants that might be picked up during handling and storage on thermal stability of one fuel.
