Asphaltenes Conversion through One-step Emulsion Upgrading Process Using Molybdenum Sulfide Nano Catalysts

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.
