Evaluation of Jet Fuel Deposit Kinetics. Lot IV.

Abstract

Four selected JP-5 type Navy jet fuels were investigated with regard to their rate of thermally induced deposition using two analytical techniques. A modified research Jet Fuel Thermal Oxidation Tester (JFTOT), using a quartz-enclosed heater section in combination with a photosensitive detector, was to monitor the buildup of thermally induced fuel deposits. Concurrent with the JFTOT, tests were conducted using the Experimental Coking Apparatus (ECA) in order to establish comparable deposition rate data. The resultant Arrhenius analyses have contributed to understanding the impact of an invariant oxygen concentration on the specific fuel deposition rate. An attempt to measure the hydrocarbon peroxide associated with each fuel and the buildup of organo-peroxide with fuel temperature was inconclusive due to the variation in peroxide potential analysis (ASTM D-3703). Originator-supplied key words include: Coking.
