Spring 2021
Carbon capture utilization and storage (CCUS) play a crucial contribution in reducing CO2 emissions and obtaining net-zero emission by 2050. Adsorbent-based technology offers an opportunity to separate CO2 under mild regeneration conditions. However, low CO2 concentration and water vapour in the...

Investigation of the Adsorption of Model and Oil Sands Process-Affected Water Naphthenic Acids on Graphite
DownloadSpring 2015
Naphthenic acids (NAs) are constituents of bitumen in the oil sands deposits in northern Alberta, Canada. The extraction process of bitumen creates an enormous amount of wastewater called oil sands process affected waters (OSPW). This OSPW contains elevated concentrations of NAs, and other...

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...

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...

Spring 2013
Coagulation/Flocculation/Sedimentation (CFS), petroleum coke (PC) adsorption, and zero valent iron (ZVI) oxidation-enhanced by PC were applied for the remediation of oil sands process-affected water (OPSW), generated from oil sands operations in northern Alberta, Canada. OSPW is a complex mixture...

Probing Surface Heterogeneity, Electrochemical Properties and Bubble-Solid Interaction Mechanisms of Sulfide Minerals in Flotation
DownloadSpring 2017
The colloidal stability governed by various surface interactions including van der Waals (VDW) interaction, electrical double layer (EDL) interaction, hydrophobic interaction, and some other interactions, plays an important role in a wide range of natural phenomena and engineering applications....

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...
