The Modified Invasion Percolation (MIP) model was used to simulate the invasion of CO2 into a medium initially saturated with water and the style of capillary heterogeneity in combination with buoyancy and viscous forces were varied to yield 105 different simulation scenarios. Thereafter, the invasion of the CO2 gas is simulated using a finite difference model and the effective mass transfer coefficient is determined and linked to various styles of capillary heterogeneity. Results show that an increase in saturation does not result in an increase in mass transfer coefficient rather, the surface area, which in turn is controlled by the …
Pretreatment Of Cellulosic Biomass By Iron-Containing Magnetic Ionic Liquid Dissolution, Christopher Roth Riley
Pretreatment Of Cellulosic Biomass By Iron-Containing Magnetic Ionic Liquid Dissolution, Christopher Roth Riley
Electronic Theses and Dissertations
The focus of this project is to determine the effectiveness in the preprocessing of biomass when magnetic ionic liquids (MIL) (1-butyl-3-methylimidazolium tetrachloroferrate (Bmim[FeCl4]) and 1-ethyl-3-methylimidazolium tetrachloroferrate (Emim[FeCl4])) are used as a green solvent. Lignocellulose is a promising starting material for a plethora of products, ranging from biofuels to custom chemicals; however, lignocellulose is resistant to enzymatic degradation. Various biomass-preprocessing techniques such as microbial, mechanical, and chemical pretreatment are used for enhancing the digestibility of biomass to sugars for ethanol production. Varieties of ionic liquids have demonstrated the ability to fragment lignocellulose. However, after fragmentation, separation of biomass and ionic liquids …
Utilizing Reversible Addition Fragmentation Chain Transer For The Synthesis Of Polymeric Gene Delivery Vehicles, Jared Spoons
Utilizing Reversible Addition Fragmentation Chain Transer For The Synthesis Of Polymeric Gene Delivery Vehicles, Jared Spoons
Honors Theses
There are many techniques used today to make a variety of polymers but this thesis investigates the reversible addition-fragmentation chain transfer (RAFT) polymerization technique and illustrates the advantages and importance of using RAFT polymerization technique to make the desired polymer. The research focused on two monomer units that were to form the diblock copolymer; the hydrophilic part, oligo(ethylene glycol) methacrylate, and the cationic hydrophobic part 2-diethylaminoethyl methacrylate. The goal was to produce a target diblock copolymer with a Mn value of 44K and a PDI under 1.5 with the block sizes being a 35K Mn OEGMA chain and a 9K …
The Cooling Effect Of Cryotherapy On Power And Accuracy In The Pitching Arms Of Baseball Players, David Kimble Wilbanks
The Cooling Effect Of Cryotherapy On Power And Accuracy In The Pitching Arms Of Baseball Players, David Kimble Wilbanks
Honors Theses
As the human body does work, energy is released in the form of heat. The ability to perform the same action repeatedly and at the same intensity requires energy to be maintained. By preserving energy in sports, a reduction of injuries and an increase in performance duration would most likely be observed. More specifically in sports, for 200 years of baseball history, the pitcher has attempted to keep their arm warm during resting intervals of a game, in belief this would help sustain their level of performance. This study attempted to overturn this view. I hypothesized that by cooling their …
Performance And Stability For Room Temperature Ionic Liquid Membranes For The Dehumidification Of Methane, Dora Frances Sullivan-González
Performance And Stability For Room Temperature Ionic Liquid Membranes For The Dehumidification Of Methane, Dora Frances Sullivan-González
Honors Theses
The biogas production from organic waste—animal, sewage, landfill material— could be a valuable renewable fuel. Before this biogas—predominately bio-methane— can be converted to fuel, it must be dehumidified. Typically membrane-based gas dehumidification uses hydrophilic polymer membrane materials, such as polydimethylsiloxane (PDMS) and cellulose acetate (CA). The main problems with polymer dehumidification membranes are methane loss and the susceptibility of polymer materials to plasticization by H2O. Room temperature ionic liquid membranes (RTIL- membranes), according to recent literature, are not plasticized by water and have large water/CH4 selectivities. We built on the initial literature RTIL-dehumidification data by looking at a series of …
