Investigation of Thermal Coking Rates of Air Force Jet Fuels

Abstract

This study evaluated the rates of deposit for selected jet fuels as a function of temperature and the effect of several current fuel additives on the rates of thermal deposition. Tests were run on the fuels with various concentrations of the additives and various levels of aromatic content. Deposits were collected on stainless steel coupons using an experimental coking apparatus that was developed for this program. It was found that the breakpoint temperature decreased and the concentration of peroxide increased as the aromatic content of the fuels increased. The rate of formation of deposits increased with decreases in the breakpoint temperature. The presence of different fuel additives had substantial effects on the rate of deposition.
