Oxidative desulfurization of oil sands bitumen as pre-refining methodology to improve bitumen quality in the absence of catalysts was studied. It has potential advantages such as employing a cheap reagent (air) and moderate processing conditions (<180 °C, autogenous pressure). The specific aims...

At the heart of heavy oil and bitumen upgrading, thermal conversion technologies are found. One such process is visbreaking where bitumen is thermally converted into lighter materials. However, the conversion by visbreaking is limited by the onset of the formation of solid carbonaceous materials...

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...
