Characterization of Shale Oil Produced under Various Reduced Pressures
The crude shale oil obtained under reduced pressures by a nonisothermal technique was analyzed for physical and chemical properties. A lower pressure, higher heating rate, and higher flow rate of sweep gas resulted in a higher nitrogen content and higher values of viscosity, density, Conradson carbon, and pour point as well as a higher percentage of higher boiling distillates and a lower H/C ratio. The sulfur content remained relatively constant in the pressure range studied. As for chemical properties, a greater amount of paraffinic and aromatic compounds and increased aromaticity were observed at a lower pressure, while saturated isoprenoids decreased with decreased pressure. The olefinic fraction remained relatively constant under various pressures.
