S. Zabarnick et Rr. Grinstead, STUDIES OF JET FUEL ADDITIVES USING THE QUARTZ-CRYSTAL MICROBALANCE AND PRESSURE MONITORING AT 140-DEGREES-C, Industrial & engineering chemistry research, 33(11), 1994, pp. 2771-2777
The quartz crystal microbalance (QCM) and pressure monitoring are used
for the evaluation of jet fuel additives for the improvement of jet f
uel thermal stability. The mechanisms of additive behavior are determi
ne by measuring the time-dependent deposition with the QCM and oxidati
on by pressure measurements. Studies at various additive concentration
s permits the determination of optimum additive concentrations. Additi
ve packages made of mixtures of antioxidants, detergent/dispersants, a
nd metal deactivators are shown to yield good improvements in thermal
stability over a wide range of jet fuel types.
