The work presented in this dissertation provides a novel technique of manipulation of colloidal entities during membrane filtration based on an AC electrokinetic phenomenon called dielectrophoresis. First, the influence of dielectrophoretic (DEP) forces created on a membrane surface to levitate...

Two separations are necessary to enable the post-combustion capture of CO2. The fraction of CO2 in a flue gas stream must first be separated from the diluents present and then the concentrated stream of CO2 must be thoroughly dried in order for it to be compressed for sequestration. This work...

The objective of this research was to develop new molecular sieve materials and to examine their applications in adsorptive gas separation processes. Several techniques to modify zeolite molecular sieve materials were developed, including a new pore size control mechanism and novel surface...

Selective ring opening of naphthenic molecules is a preferred reaction to increase cetane number of fuels, and it should result in products with no loss in molecular weight and longer alkyl side chains. Benzocyclopentane (indan) ring opening was studied under hydrogen atmospheric pressure at 609...

Membrane-based processes have the potential to overcome the limitations of conventional hydrogen separation techniques such as high energy consumption and environmental concerns. Natural zeolite membranes have recently been shown to demonstrate apparent molecular sieving of H2 from H2/CO2...

Coupling supercritical CO2 extraction with membrane separation leads to energy savings by recycling CO2 at supercritical state while separating extract components. Commercially available polyamide-based membranes are commonly used with coupled systems due to their availability and robust...

The fluids produced from a thermal enhanced recovery process such as steam assisted gravity drainage (SAGD) and cyclic steam stimulation (CSS) are pumped to the surface where bitumen and water are separated. This initial fluid is known as SAGD-PW (produced water). A potential way to effectively...

Bimetallicity is known to provide synergistic effects and improve catalytic performance of monometallic counterparts in a variety of applications. Conventional impregnation methods for supported catalyst preparation do not allow for the control of bimetallic nanoparticle structure or size, which...

Recently, considerable research has been conducted into solid-acid catalyzed carbonylation of dimethyl ether (DME) to methyl acetate (MeOAc), which can be further used for the iodine-free production of ethanol or acetic acid. The zeolite mordenite (H-MOR) is known as a potential catalyst but is...
