In this study, the mineralogy, surface properties, and morphology of fine solids in bitumen froth before and after hydrothermal reactions were investigated. It was observed that clay minerals such as kaolinite and illite did not go through significant mineralogical changes after the reaction....
Better definition of asphaltene structure is needed to develop new technology for upgrading, and to understand various bitumen properties. Analysis of asphaltene structure is hampered by aggregation of molecules at a length scale of 5 to 10 nm. At 300°C, the addition of aromatic solvents can...
