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...

Fall 2023
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...

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...

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...

Dependence of the Interfacial Adhesion between Two Different Types of Material on their Electron Work Function and Electrical Conductivity
DownloadFall 2021
We observed and investigated a novel interfacial phenomenon related to the dependence of interfacial bonding or adhesive force (Fad) between two substances on the difference in their Electron Work Functions (EWF) or Δφ, and developed a model to quantify such a dependence. First, using...
