Abstract:

The technical effort described herein was directed at determining the feasibility of using the Redox Chemiluminescence Detector RCD for the selective detection of cycloalkanes and antioxidants in jet fuels. Three catalysts gold, palladium, and platinum were prepared and evaluated at several reaction temperatures. The gold catalyst at 300 deg C produced the best selectivity for cycloalkanes 401 for hexane and 31 for nonane. As temperature was increased, however, the selectivity for cycloalkanes decreased. The palladium and platinum catalysts did not demonstrate adequate selectivity under the examined test conditions. Overall, the metal catalysts examined in this study did not exhibit sufficient selectivity to permit detection of cycloalkanes versus acyclic alkanes. The selectivity of the RCD for easily oxidized compounds eg. phenols versus hexane was typically 104 to 106. JS
