Diesel Lubricity Additive Effect on Jet Fuel Thermal Oxidative Stability with Supplementary Information on Fatty Acid Methyl Ester and Jet Engine Nozzle Performance

摘要

This report summarizes a preliminary study of the effect of Diesel Lubricity Additives (DLA) on thermal oxidative stability of distillate jet fuels as evaluated by Breakpoint in accordance with ASTM D3241 (commonly referred to as the JFTOT). The scope of this study is to test readily available jet fuel samples and perform a simple evaluation on the effect of the three primary classes of DLAs: Amides (AM), Esters (ES) and Mono Acids (MA) that might be encountered in the distillate fuel distribution infrastructure in cases such as intermittent transportation of diesel fuels and jet fuels. The objective of the main project is to determine if it is possible to observe DLA in jet fuel at levels up to 200 mg/kg with no apparent harm to thermal stability. Also included in this report are results from related studies on fatty acid methyl ester (FAME) contamination and on bench testing of jet engine nozzle performance tests with DLA contaminated jet fuel samples.
