A Study on the Effect of Temperature and Pressure on the Removal of Cyclohexane from Non-Aqueous Extraction Gangue
DownloadSpring 2015
Solvent based extraction has the potential to supplant the current hot water based extraction process as the industry standard method for recovering bitumen from mined oil sand. It has the potential for higher bitumen recovery that is less sensitive to the grade of oil sand ore being processed....

Agglomerate formation is a common phenomenon that can cause operating problems in the fluid coking reactor. When agglomerates form they provide longer diffusion paths of the reaction products through the liquid layers and liquid bridges within the agglomerate, which leads to higher mass transfer...

Fall 2012
Coke formation is a major problem in the petroleum industry because of its effect on liquid yield, catalyst deactivation, and fouling of reactor internals and downstream vessels. Carbonaceous mesophase is a liquid crystalline phase which forms during cracking of heavy oil, as a subset of coke. A...

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...

Fall 2011
Large polycyclic aromatic nitrogen containing asphaltene model compounds, with molecular weights from 535 to 702 g/mol, were catalytically hydrogenated and hydrodenitrogenated in the presence of a commercial NiMo/γAl2O3 catalyst in a stainless steel batch reactor at 370 °C and 17.9 MPa total...

Spring 2015
The fluid coking process is an example of upgrading processes that use hot solids to heat and crack bitumen into more valuable products. When liquid is sprayed into a fluid bed of hot solids, the solids tend to agglomerate. The reactions in these agglomerates are subject to complex heating,...

Fall 2014
The aim of this study was to examine the effect of steam and fine solids on coke formation during thermal cracking of bitumen. Experiments in a batch reactor at hydrothermal conditions determined the effects of fine solids and water on the onset of coke formation, total coke yield, and defined...

Fall 2012
The use of solvents for extraction of bitumen is attractive because no wet tailings are produced. Studies have already shown that hydrocarbon solvents can achieve the same level of bitumen recovery as the current aqueous extraction method. However, solvent recovery must be very efficient to avoid...
