Canadian oilsands bitumen contains one of the highest amounts of asphaltenes (16-20 wt %) among all crude oils. Asphaltenes are the lowest value fraction of bitumen. It differs from the other fractions of bitumen because of its insolubility in paraffinic solvents. Asphaltenes are insoluble in...

Characterization of residue from direct coal liquefaction and determination of its potential applicability as a source of fuel
DownloadSpring 2015
Direct coal liquefaction is a technology for producing liquid products from coal. One of the by-products from this process is coal liquefaction residue, which is remaining coal that was not converted to liquid products during the liquefaction process. The residue is enriched in mineral matter and...

Canadian oil sands derived bitumen is a form of petroleum that has a high density and viscosity. One of the potential causes of the high viscosity of the oil sands bitumen is acid-base interactions. The main purpose of this project was to determine the influence of acid treatment and base...

In this work, low temperature ozonation of Canadian Athabasca bitumen with ozone-enriched air in the temperature range of 140 to 160°C was investigated. Due to the resonance hybrid structure of ozone, it reacts directly and indirectly with the hydrocarbon molecules. Indirect ozone reaction...
