Spring 2023
The increasing abundance of per- and polyfluoroalkyl substances (PFAS) has attracted growing interest due to concern about the potential hazards to public health and ecosystems. Due to PFAS toxicity, mobility, environmental persistence, and strong bioaccumulation, they are being further...

Adsorbents for the Removal of Naphthenic Acids from Oil Sands Process Water: Investigation of Reclamation Materials from Surface Mining of Oil Sands and Development of Biochars from Biological Sludge and Peat
DownloadSpring 2023
Crominski da Silva Medeiros, Deborah C.
Oil sands process water (OSPW) is generated in high quantities during the extraction of the bitumen from the oil sands. Naphthenic acids (NAs) are recalcitrant compounds, corresponding more than 50% of all organics in OSPW. The efficient management of OSPW is of importance to guarantee efficient...

Fixed beds are widely used in the chemical and process industry due to their simple yet effective performance. They find applications in heterogeneous catalysis (e.g., dry reforming of methane, methanol synthesis, etc.) and in adsorption (hydrogen from steam methane reforming, post-combustion CO2...

Atomistic Approach towards Sodium Citrate Role on Surface Properties of Silica and Clay Minerals
DownloadFall 2022
The use of sodium citrate as a secondary processing aid in combination with caustic significantly improved bitumen recovery, specifically in poor oil sands ores. The role of sodium citrate on wettability alteration of solid surfaces, benefiting bitumen liberation as well as improving bitumen...

Development of dynamic column breakthrough for multicomponent adsorption equilibrium and diffusion
DownloadFall 2022
Pressure and temperature swing adsorption processes are increasingly being designed and optimized computationally. The reliability of these predictions are highly dependent on the quality of the experimental equilibrium and kinetic data used in these simulations. Consistent experimental...

Effect of adsorbate’s polarity, steric hindrance, aromaticity, and boiling point on competitive adsorption in a multi-staged countercurrent fluidized bed reactor using activated carbon and zeolite
DownloadFall 2022
Understanding the multi-component adsorption of volatile organic compounds (VOCs) is of essential importance for real-world engineering applications. Various properties of VOCs can affect their competitive adsorption when there is a mixture of these compounds in the process stream. This thesis...

Structural properties of deprotonated naphthenic acids immersed in water in pristine and hydroxylated carbon nanopores from molecular perspectives
Download2021-08-05
Zhang, Mingshan, Li, Wenhui, Jin, Zhehui
We use molecular dynamic simulations to study the structural properties of deprotonated cyclohexanoic acid (DCHA) and heptanoic acid (DHA) immersed in water in pristine and hydroxylated carbon nanopores (PACNs and HACNs) in relation to NA removal by activated carbons (ACs). In PACNs, both NAs can...
