Asphaltene rejection from bitumens via supercritical fluid extraction | 1993 | asphaltene rejection; bitumen; supercritical fluid extraction; SFE; asphaltene content | Supercritical fluid extraction (SFE) of bitumen was carried out in a continuous extractor using propane as the solvent at several temperatures and pressures. The asphaltene contents of the residual fractions in the extractor were compared to the asphaltene content of the original bitumen. Asphaltene... |

Shale oil value enhancement research - Quarterly report: October 1 - December 31, 1993 | 1993 | shale oil; value enhancement; raw shale oil; market shale oil project | A major push was made to identify the hydrocarbon and heteroatom types present in raw shale oil. A comprehensive, qualitative picture of the <400°C material has been obtained. In addition to the expected types, e.g., pyridines, pyrroles, indoles and phenols, the presence of aliphatic carboxylic aci... |
