Spring 2015
Previous studies on the extraction of liquid products from coals have focused mainly on increasing the yield, with very little emphasis on the quality of the liquid products. The main goal of this study is to achieve a balance between the yield and quality of the coal derived liquids. The first...

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...

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...

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...

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...

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...

Non-aqueous extraction technologies are currently being investigated as an alternative to the conventional water based process for extracting bitumen from oil sands. The reduced dependence on fresh water and land for creation of tailing ponds makes non-aqueous technologies a greener alternative....

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...

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...
