Waste Lubricating Oil Research: Characterization of Basestocks from Used Lubricating Oils. Part 3

摘要

Physical and chemical data derived from the analysis of 10 used oils are presented in this report, the third of a four-part investigation. The 10 used lubricating oils of this report were obtained from widely divergent areas of the continental United States, and represent typical re-refinery feedstock. Collection areas ranged from the State of Washington to Florida and from southern California to Pennsylvania. A better understanding of the compound types and distribution of major structural groups in waste crankcase oils is required to make a judgment regarding the possibility and probability of producing consistent product from a given re-refinery. Identification of contaminants inherent to waste crankcase oils is pertinent to selecting proper re-refining technology even though contaminants have little or no bearing upon the final quality of product if properly and effectively removed during processing. The significant measure of product consistency lies in the composition of the petroleum base of these used oils; therefore, this investigation was directed toward the qualitative and semiquantitative measurement of compound types found in waste oils.
