Ozone oxidation of solid deposits produced by the thermal stressing of jet fuel

Temperature Programmed Oxidation (TPO) were used to characterize the carbon deposits produced by the thermal stressing of jet fuel over various catalytic and non-catalytic substrates. Such characterization was based on the oxidation reactivity of the deposits, which was closely related to their structural morphology. The high temperature and catalytic activity of the substrate might however produce some highly ordered deposits that were artifacts of the TPO analysis. To eliminate the possible complications with analyzing the carbon deposits at high temperatures, deposited substrates could be oxidized with ozone at low temperatures. The characterization of carbon deposits produced from the thermal stressing of jet fuel by TPO of O ₃ oxidized samples was compared to the characterization by TPO alone. This is an abstract of a paper presented at the 227th ACS National Meeting (Anaheim, CA 3/28/2004-4/1/2004).
