The combined gas chromatography/mass spectrometric (GC/MS) evaluation of selected high density fuel distillate fractions is completed and the results are provided in this memorandum. The objective of the combined GC/MS evaluation of these distillate fractions is to provide results for comparison among the distillate fractions and the parent hydrotreated products. The results provided in this memorandum concern two classes of distillate fraction; the 350-550°F distillate fractions from four hydrotreated products and nominal 20°F distillate fractions beginning at 350°F and terminating at 550°F generated from one of the hydrotreated products. The combined GC/MS analysis of the four 350-550°F distillate fractions were performed to determine if a distillation range, narrower than the parent hydrotreated product, would improve the high density fuel quality of the products. The analysis of the nominal 20°F distillate fractions were performed, to be used with other chemical and physical properties, to determine if a more optimum distillate range exists for high density fuels. The results of these analysis are presented below. The first discussion section presents the results from the evaluation of the 350-550°F distillate fractions and the second presents the results for the 20°F distillate fractions.
