Hydrothermal Treatment of Bitumen Froth at 250 °C: Impact on Bitumen Properties and Role of Clay Minerals
DownloadFall 2023
Bitumen froth produced in the hot water extraction process of mined oil sands consists of about 60 wt % bitumen, 30 wt% water and 10 wt% mineral solids. To convert the bitumen in bitumen froth into a marketable product, the water and solids need to be separated. Solvent-based froth treatment...

Hydrothermal Treatment of Low Rank Coal for Making High Solid Loading and Stable Coal Water Slurries
DownloadFall 2014
The objective of this research is to understand the effect of hydrothermal dewatering (HTD) on surface properties, stability and rheological behavior of lignite water slurry (LWS). The surface forces between coal particles are found to be attractive after HTD, which is proven by contact angle and...

Organically-Modified Clay Minerals in Oil Sands: Characterization and Effect of Hydrothermal Treatment
DownloadFall 2017
The intimate association between bitumen components and clay minerals is an important feature of oil sands fine solids. These organically-modified clay minerals cause serious problems in Canadian oil sands production: hindering bitumen extraction, stabilizing water-in-bitumen emulsions, fouling...
