Desulfurization of thiophene and dibenzothiophene with hydrogen peroxide in a photochemical microreactor

Creator:: Al-Raie, Ali H.
Abstract:: Sulfur content of fuels and desulfurization of fuels is becoming an important environmental restriction and regulatory issue. In this study new technology for the desulfurization of fuels is considered. Micro scale reactors are introduced for desulfurization of thiophene and dibenzothiophene. Thiophene and dibenzothiophene are mixed with hexane at concentration, C₀...

Synthesis and evaluation of PEO-coated materials for microchannel-based hemodialysis

Creator:: Heintz, Keely
Abstract:: The marked increase in surface-to-volume ratio associated with microscale devices for hemodialysis leads to problems with hemocompatibility and blood flow distribution that are more challenging to manage than those encountered at the conventional scale. In this work, stable surface modifications with pendant polyethylene oxide (PEO) chains were produced on polycarbonate...

Experimental investigation of supercritical heat transfer of carbon dioxide in parallel square microchannels with a single-wall constant heat flux boundary condition

Creator:: Zada, Kyle R.
Abstract:: In the vicinity of the pseudocritical point, supercritical carbon dioxide (sCO₂) undergoes a steep change in properties from “liquid-like” to “gas-like” as it is heated at a constant pressure. At the same time, there is a large spike in specific heat which can yield high heat transfer coefficients and heat...

Oxidative desulfurization of dibenzothiophene with tert-butyl peroxide in a carbon nanotube supported corona discharge microreactor

Creator:: Caple, Kevin R.
Abstract:: Sulfur content in fuel is an increasingly important environmental concern. A commonly used method for the removal of sulfur bearing species from fuel is through hydrodesulphurization. However, due to the implementation of Ultra-Low Diesel Sulfur (ULDS), deeper desulphurization techniques must be explored. In this study, a single phase oxidative desulphurization...

CdS nanocrystalline thin films deposited by the continuous microreactor-assisted solution deposition (MASD) process : growth mechanisms and film characterizations

Creator:: Su, Yu-Wei
Abstract:: The continuous microreactor-assisted solution deposition (MASD) process was used for the deposition of CdS thin films on fluorine-doped tin oxide (FTO) glass. The MASD system, including a T-junction micromixer and a microchannel heat exchanger is capable of isolating the homogeneous particle precipitation from the heterogeneous surface reaction. The results show...

Synthesis of titanium dioxide nanorods using a continuous flow microreactor

Creator:: Yen, Wei-Liang
Abstract:: The primary goal of this thesis is to synthesize titanium dioxide nanorods using a continuous flow microreactor. Titania powder, one of the most important particulate materials is used for many purposes owing to its excellent optical properties of a high refractive index leading to high hiding power and whiteness of...

Half Array Architecture for Advancing Microchannel Heat Recuperation to Market

Creator:: Brannon, Samuel T.
Abstract:: High temperature microchannel heat recuperators (HTμRs) offer an efficient means of improving reactor process thermal efficiency by offering smaller form factors due to increased heat transfer surface area density and volumetric heat transfer rate over traditional heat exchanger designs. To date, HTμRs face cost and reliability challenges. In this work,...

CO₂ Reduction in Microscale-Based Corona Reactor : Experiments and Modeling

Creator:: Miao, Yu
Abstract:: Global warming is becoming an increasingly important environmental concern and CO₂ is considered as the major cause of global warming. Creating useful applications for CO₂ would generate alternatives to merely venting CO₂ to the atmosphere, and decreasing the carbon intensity of human activities. Among various methods of CO₂ utilization, conversion...

Force Prediction in the Compression Sealing of an Ultra-thin Elastoviscoplastic Membrane

Creator:: McNeff, Patrick Scot
Abstract:: The objective of this paper is to demonstrate a method for mechanically characterizing a 25 μm thick elastoviscoplastic hemodialysis membrane and for quantifying the force required to use that membrane in compression sealing. First, methods are developed for mechanically characterizing the thin elastoviscoplastic membrane. Then, a finite element model is...

Density Functional Theory Investigation of CH Coupling and CH Hydrogenation Reactions on Different Cobalt Surface Facets and Fischer-Tropsch Temperature Swing Reactor Optimization

Creator:: Petersen, Dennis F.
Abstract:: Fischer-Tropsh Synthesis is a chemical process that converts CO and H₂ (syngas) into long stable hydrocarbon chains to use as fuel. This process suffers from large product distribution that requires expensive post processing. In this study, the reaction mechanism of hydrocarbon chain growth on Co is investigated on different surface...
