Abstract : A study was made of the use of additives to prevent or retard the deterioration of JP-6 fuel thermal stability during storage. Fuel-additive blends were stored at 130 F in sealed 15-gallon steel drums for periods up to 16 weeks. Thermal stability was measured by means of a modified fuel coker developed during this program, using helium pressurization instead of a fuel pump. The standard ASTM-CRC fuel coker and the EppiCRC modified fuel coker were found to be unsuitable for this purpose, owing to contamination of the test sections with pump wear debris. A total of 52 additives were submitted by industry for evaluation, from which 19 were selected by screening tests for inclusion in the hot-room storage program. Three JP-6 fuels were used as the base stocks for additive evaluation. Under storage conditions giving a 100 F decrease in base fuel thermal stability, four additives or combinations of additives were found to be effective in maintaining thermal stability. These results indicate that the use of additives is a feasible approach to solving current problems in this area. (Author)
