Modeling the Performance and Hydrodynamic Behavior of a Countercurrent Multistage Fluidized Bed Adsorber
DownloadSpring 2021
Fluidized bed (FB) adsorbers provide excellent gas-solid contact at low pressure drops which allows for effective handling of large flow rates. However, the design, operation, and modeling of FB adsorbers could be challenging due to the complex processes involved. The goal of this research is to...

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...

Novel feed enzyme delivery method: Binding exogenous feed enzymes to Bacillus spores to improve enzyme stability and total tract digestibility
DownloadFall 2018
The effects of binding feed enzymes to Bacillus subtilis (strain RK28) spores on enzyme stability and digestion in cattle were studied in comparison to unbound enzymes. Optimal conditions for adsorbing six different enzymes (α-amylase, β-glucanase, feruloyl esterase, phytase, purified xylanase,...

Phase Behavior, Adsorption Behavior and Interfacial Properties of Fluids in Shale Reservoirs
DownloadFall 2018
Shale oil/gas resources are becoming an increasingly important energy resource. Compared to conventional reservoirs, shale generally consists of a large proportion of organic matters. Organic matter is mainly comprised of kerogen, within which a significant amount of nanopores may reside. Due to...

Fall 2009
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...

Production and Application of Different Waste-derived Sustainable Materials for the Removal of Naphthenic Acids Related to Oil Sands Process Water
DownloadSpring 2024
Oil sands process water (OSPW) is generated in a large volume during the bitumen extraction process from the oil sands. Naphthenic acids (NAs) are recalcitrant compounds that contribute to the toxicity of OSPW, which need effective treatment before being released into the environment. In the...

Reclamation of Unconventional Oil Processed Water through the Adsorption of Naphthenic Acids by Carbon Xerogel
DownloadFall 2017
This study examines the use of carbon xerogel (CX) material for the adsorption of naphthenic acids (NAs). The adsorption of NAs is crucial for the reclamation of unconventional oil processed water, more specifically Alberta’s oil sands process-affected water (OSPW). CX material is synthesized at...

Regenerable Composites for Removal of Organic Dye in Aqueous Media and Water in Heavy Oil and the Associated Interaction Mechanism
DownloadSpring 2018
Water plays an indispensable role in all aspects of life, including farming, domestic and industrial uses. In industries, water has been extensively applied in mining, production and surface treatment, producing a large quantity of contaminated water that threatens human health, endangers...

Removal of Heavy Metal Ions and Diethylenetriamine Species from Solutions by Magnetic Activated Carbon
DownloadSpring 2013
Even though activated carbon is widely used in the removal of contaminants from effluents, it is difficult to be completely recovered by screening or classification. In this project, we prepared a magnetic form of activated carbon (M-AC) by co-precipitation of iron oxides onto activated...

Removal of Organic and Inorganic Contaminants from Oil Sands Tailings using Carbon Based Adsorbents and Native Sediment
DownloadFall 2013
The extraction and refinement of oil sands bitumen produces substantial quantities of liquid tailings and solid coke. Tailings contain metals and naphthenic acids, which require remediation before mine closure. Adsorption is a potential remediation technique which may reuse stockpiled petroleum...
