TL;DRAbstract

This dissertation considers the development of new analytical techniques to characterize shale oil, with emphasis on the heteroorganic compounds. A class separation precedure using preparative liquid chromatography on an amino-bonded silica support was developed to allow separation of shale oil into four chemical classes, namely: (1) hydrocarbons (alkanes/alkenes), (2) polynuclear aromatics, (3) acids and neutral polars, and (4) bases. This procedure was applied to the analysis of two different types of shale oil, Tosco II and In-Situ. All four classes of compounds were then characterized by capillary gas chromatography with flame ionization detection and some were also examined with the thermionic nitrogen specific detector. The acids and bases were further characterized by capillary gas chromatography with interfaced mass spectroscopy. Comparison of the two oils showed that although the level of heteroorganic compounds is different, the distribution of compounds within the same class
