The impact of various ozone pretreatment doses on the performance of endogenous microbial communities for the remediation of oils sands process-affected water
DownloadFall 2015
In this study, the effects of different ozone pretreatment doses on the performance of endogenous microbial populations in degrading naphthenic acids (Nash and Traver) for the treatment of oil sands process-affected water (OSPW) were evaluated. The results showed that ozonation enhanced the...

Solvent extraction of coal: Influence of solvent chemical structure on extraction yield and product composition
DownloadSpring 2012
In recent years the need for new carbon sources to supplement crude oil for the production of fuels and chemicals, again focused on coal as suitable candidate. Old and new technologies are being developed to convert coal in valuable products. An old technology such as solvent extraction of coal...

Rheology of Bitumen at the Onset of Asphaltene Aggregation and its Effects on the Stability of Water-in-Oil Emulsion
DownloadFall 2015
Asphaltenes are the heaviest fraction of bitumen. Asphaltenes not only play an important role in the high viscosity of bitumen but also in the water-in-oil (W/O) emulsion stability. Nevertheless, their exact function in the stability mechanism of W/O emulsion still remains unresolved. It is...

Albertan coal has been used to produce extracts as precursor for production of anode coke. Coal extractability was studied using digestion with Tetralin in a 500 ml reactor. Different operating conditions were tried and optimum conditions were chosen for runs with coal-derived solvents. Extracts...

Spring 2011
To ensure oil sands process water (OSPW) is suitable for discharge into the environment, advanced water treatment technologies are required. In this study, integrated ozonation-biodegradation was investigated as a potential treatment option for OSPW. The treatment efficiency was evaluated in...

Spring 2012
Modelling of solvent extraction was studied using 1,2,3,4–tetrahydronaphtalene (tetralin) and Poplar coal (lignite). A kinetic model was developed taking into account temperature, mass transfer limitations and dominating events (physical or chemical) during coal liquefaction. It was found there...

Microalgae grow heterotrophically and produce high value pigments, nutraceuticals, pharmaceuticals, feeds, and biofuels. The growth rate, nutrient medium, growth density, and oil content strongly affect the economics of heterotrophic microalgae fermentation systems. This thesis explores the...

Drop transfer from one solid surface to another through stretching liquid bridges between them is important for many industrial applications. Due to the different dominate forces, three possible regimes exist: Quasi-static Regime, where the transfer process is only dominated by surface forces;...

Fall 2013
Solvent extraction of coal is a method to produce low molecular weight products from coal. It also can be used as a pretreatment for Direct Coal Liquefaction to enhance its efficiency. Yield, rate and nature of coal dissolution at low temperatures (25-150°C) and short contact time have been...

Fabrication and Characterization of Photolithographically Patterned Rough Surfaces Demonstrating Extreme Contact Angle Behavior
DownloadFall 2014
This thesis features experimental work done to fabricate and characterize silicon surfaces patterned using photolithographic techniques, both standard and novel, to produce a variety of surfaces with roughness of controlled geometric properties. In specific, one set of the surfaces fabricated...
