Characterization of Athabasca asphaltenes separated physically and chemically using small-angle X-ray scattering
DownloadFall 2010
Athabasca asphaltenes were characterized using small-angle X-ray scattering (SAXS) with synchrotron radiation. Two methods were used to separate asphaltenes from Athabasca bitumen. Conventional chemical separation by precipitation with n-pentane, and physical separation realized by passing...

Developing High Precision Heat Capacity Correlations for Organic Solids and Liquids - Extending to Biofuels and Sugars
DownloadSpring 2018
There is a great need for easily accessible and accurate physical property data in the heavy oil industry, the pharmaceutical industry, and other heavy molecule guided productions. In recent years, high precision predictive correlations for isobaric heat capacities of heavy and ill-defined...

Fall 2015
Hydrocarbon-based liquid crystal domains have been identified in unreacted heavy fractions of petroleum from Athabasca bitumen and other hydrocarbon resources worldwide. These liquid crystal domains have also been shown to transfer from the hydrocarbon-rich phase to the water-rich phase during...

Phase Diagrams for Asphaltene and Asphaltene-Rich Hydrocarbons + Polystyrene + Toluene mixtures
DownloadFall 2018
Heavy oils are nano-colloids comprising a continuous maltene-rich liquid phase and a nano-dispersed asphaltene-rich phase separable by filtration that are macroscopically homogeneous. The asphaltene-rich phase can aggregate and deposit, causing technological risk and process operation challenges...
