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...

Sources of flow maldistribution in microreactor-assisted synthesis of ceria nanoparticles

Creator:: Tseng, Chih-Heng
Abstract:: Recent efforts show that microchannel technologies have much to offer the field of nanomanufacturing: the structuring of matter on the order of one billionth of a meter. During the synthesis of nanomaterials, microchannel reactors take advantage of large surface-to-volume ratios to accelerate heat and mass transport. This accelerated transport allows...

Deep desulfurization of diesel fuel using a single phase photochemical microreactor

Creator:: Jones, Jacob Aaron
Abstract:: There is an urgent need to lower the concentration of sulfur in diesel fuels. Growing concern over environmental effects caused by burning sulfur-containing diesel has led the world to higher standards in fuel refinement. Because of these lower standards, many techniques have been researched to remove sulfur containing compounds or...

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...

Synthesis of colloidal metal oxide nanocrystals and nanostructured surfaces using a continuous flow microreactor system and their applications in two-phase boiling heat transfer

Creator:: Choi, Chang-Ho
Abstract:: Metal oxide nanocrystals have attracted significant interests due to their unique chemical, physical, and electrical properties which depend on their size and structure. In this study, a continuous flow microreactor system was employed to synthesize metal oxide nanocrystals in aqueous solution. Assembly of nanocrystals is considered one of the most...

Oxidative desulfurization of dibenzothiophene with tert-butyl hydro peroxide in a photochemical micro-reactor

Creator:: Hebert, Eilleen M.
Abstract:: Sulfur content in fuels is an increasingly critical environmental issue. Hydrodesulfurization removes sulfur from hydrocarbons; however, further desulfurization is necessary in fuels. New methods are required. In this study, micro-scaled single phase oxidative desulfurization is explored. An ultraviolet light-assisted micro-reactor is introduced for desulfurization of dibenzothiophene. Dibenzothiophene is mixed with...

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...

Nonthermal Plasma Microreaction Engineering for Gas and Liquid Processing

Creator:: Pommerenck, Justin
Abstract:: Atmospheric pressure plasma is non-thermal at millimeter to micrometer separations. It represents an alternative low exergy initiator of many chemical reactions. In many instances heat, light or sound are not efficient providers of the necessary energy to overcome chemical activation barriers. The focus of this research is applying dc nonthermal...
