Activation of Delayed and Fluid Petroleum Coke for the Adsorption and Removal of Naphthenic Acids from Oil Sands Tailings Pond Water
DownloadSpring 2011
Oil sands companies produce substantial quantities of tailings known to contain high concentrations of dissolved organic by-products. The use of petroleum coke was proposed as a potential adsorbent for organic contaminant removal from tailings pond water. Physical activation was used to create a...

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...

Fall 2013
In this research two-dimensional mathematical models were developed to study adsorption of single component volatile organic compounds (VOCs) and competitive adsorption of n-component mixtures of VOCs from dilute gas streams in a fixed-bed adsorber. The models consist of the macroscopic mass,...

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...

Adsorption and Microwave Regeneration for Controlling Volatile Organic Compounds Emissions from Automotive Paint Booths
DownloadFall 2016
Adsorption is a widely used method for control of organic compounds produced during painting operations. After adsorption, the loaded adsorbent should be regenerated to recover the adsorbates and reuse the adsorbent for subsequent adsorption/regeneration cycles. Accumulation of non-desorbed...

Spring 2016
Vehicle painting booths are among the major sources of volatile organic compounds (VOCs) emissions in the auto manufacturing sector. A challenge with controlling VOCs by adsorption onto activated carbon (AC) is the occurrence of strongly, or even permanently, adsorbed species. Irreversible...

Effect of Desorption Purge Gas Oxygen Impurity on Heel Formation During Regeneration of Beaded Activated Carbon Saturated with Organic Vapors
DownloadFall 2017
Irreversible adsorption or heel formation during cyclic adsorption/regeneration of high molecular weight volatile organic compounds (VOCs) onto activated carbon decreases its adsorption capacity and lifetime. The effect of regeneration purge gas oxygen impurity on activated carbon performance,...

Effects of Adsorbate Properties on Heel Buildup on Activated Carbon Fiber Cloth during Electrothermal Regeneration
DownloadSpring 2017
Automotive painting booths are a major source of volatile organic compounds’ (VOCs) in the automotive manufacturing sector. Adsorption on activated carbon (AC) has been widely used as a low cost and energy efficient VOC control method. A major challenge associated with the cyclic...

Fall 2017
Water contamination by ammonium ions presents huge risks to the ecosystems. This work evaluated the potential application of digested sludge pyrolyzed biochar on ammonium removal. Anaerobic digester sludge was collected from a municipal wastewater treatment plant in Alberta, Canada and pyrolyzed...

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...
