Spring 2016
Canada has the world’s largest oilsands reserves. Part of the reserves is being considered as marginal and is not profitable to recover using current technology. Autoxidation (oxidation with air) is a potential upgrading strategy to produce more valuable products from the oilsands derived bitumen...

Fall 2021
Oilsands bitumen produced from Alberta, Canada contains 14–20 wt.% n-pentane insoluble asphaltenes. Separation of asphaltenes from the bitumen by solvent deasphalting has the benefit of improving the properties of the deasphalted oil compared to the bitumen, for example, by decreasing its...

Use of a solvent in the oxidative desulfurization of bitumen via autoxidation; effects on viscosity and oxidation
DownloadSpring 2014
This work describes the effect that including a solvent in the reaction media of the autoxidation of Cold Lake bitumen has on the viscosity and also on the oxidation degree reached. The comparison of viscosity was performed both in the basis of equal residence time and equal oxygen conversion...
