Abstract:

The object of this work is to determine the mechanism by which gum and deposits are formed in diesel fuels, and thus how to predict and prevent their formation. We have been following the development of deposit precursors during oxidations of pure hydrocarbons at 130 C by field ionization mass spectrometry FIMS, and also testing high performance liquid chromatography HPLC for the same purposes. HPLC might be a convenient and economical substitute for FIMS. The previous report, Interim Report No. 1 March 22, 1982, included all useful data on this project since the joint Final Report of October 1, 1981 to NASA-Lewis and ARO. The present report includes data on deposit formation and rates of oxidation of several diesel fuels supplied by the U.S. Army Fuels and Lubricants Research Laboratory at San Antonio, done during the previous year, which have not yet appeared in any written report.
