The rheological properties of heavy oil and bitumen depend on factors such as temperature, pressure, diluent type and diluent composition, as well as sample shear and thermal histories and shear conditions during measurements. Each of these factors can affect the value of apparent viscosity...

Asphaltenes are the heaviest components in crude oil. It is generally believed that asphaltenes adsorbed at oil/water interface can form a protective layer to stabilize the water-in-oil emulsions. Therefore, it is of both fundamental and practical importance to understand the adsorption kinetics...

In industrial visbreaking processes, the conversion typically takes place at ~450 °C and the extent of conversion is limited by the coking propensity of the feed. Some of the older literature on bitumen upgrading reported that it was possible to substantially upgrade the straight run product at...

The demand for accurate bitumen-pentane mass transfer data was the main motivation behind this research. Difficulties such as complex phase behavior, high viscosity and opacity of the hydrocarbon invariably lead to failure of conventional techniques to measure mass transfer coefficients...

Crude oils contain a distribution of molecules with diverse chemical structures and molecular weights. Asphaltenes are considered the most problematic of these structures. We have investigated the adsorption and aggregation of asphaltenes on surfaces using scanning probe microscopy. Modifying the...

Microwave Heating Of Non-Aqueous Oil Sands Extraction Gangue: Study Of Optimal Cyclohexane-Water Mass Ratio And Solvent Recovery Rate
DownloadFall 2023
Non-aqueous bitumen extraction processes (NAE) of mined oil sands ore have been investigated to circumvent the environmental and operating limitations of the current hot water-based technology. However, one primary challenge of NAE is a solvent recovery that meets environmental and economic...

The oil sands of Western Canada are among the most abundant and economically important unconventional petroleum resources. Hydrocarbon extraction from oil sands is conducted using warm water or in situ technologies that face considerable environmental challenges. Oil sands can also be valorized...

Asphaltenes are the heaviest component in crude oil and bitumen. The molecular interactions and interfacial behaviours of asphaltenes are closely related to many challenging issues in oil production, which are believed to play an important role in stabilizing water-in-oil (W/O) and oil-in-water...

Natural Zeolite Catalysts for the Integrated Cracking, Waterless Extraction and Upgrading of Oilsands Bitumen
DownloadSpring 2012
Canadian oilsands bitumen represents one of the largest petroleum reserves in the world, but extraction of that resource raises significant environmental, operational and quality-related challenges. Current extraction processes are water intensive, generating high volume tailings ponds that are...
