Characterization of DOE reference oil shales: Mahogany Zone, Parachute Creek Member, Green River Formation Oil Shale, and Clegg Creek Member, New Albany Shale
Measurements have been made on the chemical and physical properties of two oil shales designated as reference oil shales by the Department of Energy. One oil shale is a Green River Formation, Parachute Creek Member, Mahogany Zone Colorado oil shale from the Exxon Colony mine and the other is a Clegg Creek Member, New Albany shale from Kentucky. Material balance Fischer assays, carbon aromaticities, thermal properties, and bulk mineralogic properties have been determined for the oil shales. Kerogen concentrates were prepared from both shales. The measured properties of the reference shales are comparable to results obtained from previous studies on similar shales. The western reference shale has a low carbon aromaticity, high Fischer assay conversion to oil, and a dominant carbonate mineralogy. The eastern reference shale has a high carbon aromaticity, low Fischer assay conversion to oil, and a dominant silicate mineralogy. Chemical and physical properties, including ASTM distillations, have been determined for shale oils produced from the reference shales. The distillation data were used in conjunction with API correlations to calculate a large number of shale oil properties that are required for computer models such as ASPEN. There was poor agreement between measured and calculated molecular weights for the total shale oil produced from each shale. However, measured and calculated molecular weights agreed reasonably well for true boiling point distillate fractions in the temperature range of 204 to 399/sup 0/C (400 to 750/sup 0/F). Similarly, measured and calculated viscosities of the total shale oils were in disagreement, whereas good agreement was obtained on distillate fractions for a boiling range up to 315/sup 0/C (600/sup 0/F). Thermal and dielectric properties were determined for the shales and shale oils. The dielectric properties of the reference shales and shale oils decreased with increasing frequency of the applied frequency. 42 refs., 34 figs., 24 tabs.
