Abstract
Shale oil recovered from Fischer assays of fresh and artificially weathered oil shales have been compared using 1H and 13C nuclear magnetic resonance spectroscopy and elemental analyses. Rundle, Julia Creek and Green River shales were exposed to air at 100 °C for 60 weeks to simulate either geological weathering, or oxidation during drying or stockpiling prior to retorting. As a result of oxidation, the oils became more aromatic, with higher oxygen contents and shorter average aliphatic chain lengths. Variations in the distribution of phenols, acids and ketones, as well as heterocyclic compounds containing nitrogen and sulphur, have been detected.
