Research output: Contribution to journalConference articlepeer-review


Thermal stressing of gasoline, jet, and diesel fuels were performed in the presence of stainless steel, superalloys, and quartz surfaces at 350° and 475°C in a flow reactor. Fuel type, sulfur content, and metal surface composition played significant roles in determining the amount of carbon deposit accumulation and chemical nature of the deposits. In addition, morphological characterization of carbon deposits formed on automobile fuel injectors and aircraft nozzles were carried out by SEM/EDS and XPS to understand the solid formation mechanisms. Research efforts on understanding the effects of metal surfaces on deposit formation will help eliminate the operational problems associated with carbon deposit accumulation on various components of fuel delivery and combustion systems. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA, 8/22-26/2004).
