A novel oil sands bitumen emulsion upgrading process was evaluated by analyzing the conversion of asphaltenes, hydrodemetalization  and hydrodesulfization and structural changes of the asphaltenes during the upgrading. In situ H2 was found to be effective for oil sands bitumen emulsion pretreatment by removing asphaltenes and reduce coke formation. Thermal treatment achieved higher asphaltene conversion and higher metal removal, but the coke yield was significantly higher.
