Utilization Of Commercial Phosphonium And Ammonium Ionic Liquids In Enhanced Oil Recovery Of Carbonate Reservoirs, Nada Berrandjia
Utilization Of Commercial Phosphonium And Ammonium Ionic Liquids In Enhanced Oil Recovery Of Carbonate Reservoirs, Nada Berrandjia
Thesis/ Dissertation Defenses
Despite advancements in renewable energy, oil and gas still dominate global energy supply, while a substantial portion of original oil in place (OOIP) remains unrecovered through conventional recovery methods. One of the most effective approaches used to mobilize residual oil is chemical enhanced oil recovery (CEOR) through mechanisms such as reduction of interfacial tension (IFT), alteration of wettability, emulsification, and improved displacement efficiency. Recently, ionic liquids (ILs) have gained interest as alternative CEOR agents due to their tunable structure and superior stability under harsh reservoir conditions. This thesis experimentally investigates the potential of low-cost and commercially available ILs for enhanced …

Thermo-Chemical Recycling Of Waste Plastics Containing Halogenated Polymers (Br−, Cl−, F−) Using Potential Additives, Mohamed Shafi
Thermo-Chemical Recycling Of Waste Plastics Containing Halogenated Polymers (Br−, Cl−, F−) Using Potential Additives, Mohamed Shafi
Thesis/ Dissertation Defenses
Plastic waste handling is a daunting task due to the presence of halogenated polymers, specifically those cluttered with bromine (Br), chlorine (Cl), and fluorine (F). Halogenated plastics can be mixed with other polymers in the general plastic waste, particularly in the recycling stream. Brominated flame retardants (BFRs) are mainly present in e-waste and from the use of flame retardants in household items, textiles, and furniture. Plastics from discarded electronics often contain significant levels of bromine and chlorine, predominantly from flame retardants and plasticizers. Being the most deployed thermoplastic worldwide, waste polyvinyl chloride (PVC) generation is expected to increase by about …
Data-Driven Machine Learning Applications For Predictive Modeling Of Petrochemical And Ecofrendly Systems, Noora Al Mansoori
Data-Driven Machine Learning Applications For Predictive Modeling Of Petrochemical And Ecofrendly Systems, Noora Al Mansoori
Thesis/ Dissertation Defenses
Traditional experimental approaches in industrial processes, such as Fourier Transform Infrared Spectroscopy (FTIR) spectroscopy, thermogravimetric analysis (TGA), and well-drilling operations, are often constrained by time, cost, and operational limitations. This research explores the application of data-driven Machine Learning (ML)-based predictive modeling to improve efficiency and reduce dependency on resource-intensive experimentation. The study develops ML models for three distinct processes: FTIR intensity prediction of bitumen thermal cracking products, thermal degradation of Medium-Density Fibreboard (MDF) using TGA data, and Rate of Penetration (ROP) prediction in petrochemical industry. Six algorithms: Linear Regression (LinReg), Partial Least Squares Regression (PLSR), Support Vector Regression (SVR), Gradient …
Engineering Bio-Based Poly (Ethylene Furanoate) Blends And Nanocomposites, Safa Fadl Eldin Mohamed
Engineering Bio-Based Poly (Ethylene Furanoate) Blends And Nanocomposites, Safa Fadl Eldin Mohamed
Thesis/ Dissertation Defenses
The growing demand for sustainable materials has directed attention toward bio-based polymers such as poly(ethylene furanoate) (PEF), a 100% bio-derived alternative to PET. While PEF offers excellent gas barrier and thermal properties, its limited mechanical strength restricts its use. This study explores polymer blending and nanocomposite strategies to enhance PEF’s mechanical and electrical performance.
Blending PEF with linear low-density polyethylene (PE) using reactive compatibilizers (SEBS-g-MA, PE-g-MA) significantly improved ductility and tensile toughness. Interfacial reactions between PEF and compatibilizers transformed the blend morphology, resulting in improved flexibility suitable for packaging applications.
Electrically conductive composites were developed by localizing graphene nanoplatelets (GNP) …

Developing A New Method For Brine Purification And Reducing Salinity Using Recycled Carbon Fiber, Fatemeh Bahaeddin
Thesis/ Dissertation Defenses
Brine water, defined as hot and high salt content water, can be produced in large amounts from water desalination. The potential environmental impacts of brine disposal were evaluated in several studies. Minor variations in water salinity and temperature can significantly influence marine ecosystems. Elevated salinity levels disrupt the osmotic equilibrium between aquatic organisms and their surroundings, which leads to cell dehydration. Various disposal techniques have been implemented recently, including surface water discharge, sewage discharge, deep-well injection, evaporation ponds, and land application. However, these brine disposal techniques are unviable due to their high capital costs and limited applicability. In recent years, …

Development Of Novel Nanobiocatalysts For Enhancing Carbon Dioxide Capture, Merna Tarek Farag
Thesis/ Dissertation Defenses
The emissions of greenhouse gases to the atmosphere cause a climate change that has devastating impacts. Therefore, reaching the net zero goal, which is the balance between the amount of greenhouse gas emitted to the atmosphere and that removed from it, is critical for the future of our planet unless the net-zero goal is achieved soon, the impacts of climate change will continue to worsen, with severe consequences for ecosystems, human health, and global security. Achieving this goal requires a fundamental shift in the way we produce and consume energy, including the rapid transition to renewable energy sources with improvements …

This thesis aims to explore the use of Zeolitic Imidazolate Framework-L (ZIF-L) as a support for immobilizing alcalase and its potency in producing protein hydrolysates. ZIF-L was synthesized at room temperature using an aqueous solution, and alcalase was immobilized through adsorption batch experiment. The successful immobilization of alcalase on ZIF-L was confirmed through Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and thermogravimetric analysis (TGA). The maximum adsorption capacity of alcalase on ZIF-L was determined to be 672.1 ± 5.5 mg g-1 at 40°C using an initial protein concentration of 5 mg mL-1. Adsorption equilibrium data suggested …

Thesis/ Dissertation Defenses
This research focuses on the development and application of Metal-Organic Frameworks (MOFs)-based nanocomposites for the photocatalytic removal of pharmaceutical contaminants, with a specific emphasis on ciprofloxacin (CIP). The photocatalytic degradation of CIP was investigated using as-synthesized photocatalysts of TiO2 nanowires (TiO2NWs), bare MOF of NH2-MIL-125, TiO2NW/NH2-MIL-125 composite, and Lanthanum (La)-doped composite. Intriguingly, the TiO2NW/NH2-MIL-125 composite exhibited the highest efficiency, achieving a photodegradation rate of 0.0111 min-1, surpassing the independent performances of bare MOF of NH2-MIL-125 and TiO2NW. The observed efficiency was attributed to the formation of a Z-scheme heterojunction …

Thesis/ Dissertation Defenses
Middle East petroleum industry is currently searching for the most suitable enhanced oil technique to improve the oil recovery from local oil reservoirs. The biggest challenge for the application of enhanced oil recovery (EOR) in the Middle East is the harsh environment (high salinity and temperature). Surfactant (synthetic or natural) is one of the enhanced oil recovery (EOR) major players considered for application in the Middle East. However, synthetic surfactants have several drawbacks, such as being economically unattractive and their high levels of toxicity. This study investigated the possible use of natural surfactant extracted from the leaves of three types …
