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...

A microchannel-based thermal management system for hydrogen storage adsorbent beds

Creator:: Steigleder, Leif J.
Abstract:: Hydrogen has been shown to be a promising replacement for fossil fuels for use in light duty vehicles because it is a clean, renewable and plentiful resource with a high gravimetric energy density. However, in order to obtain an acceptable volumetric energy density, densification of the hydrogen is required. Adsorptive...

Fabrication of precipitation-hardened aluminum microchannel cooling plates for adsorption-based hydrogen storage systems

Creator:: Pawar, Supriya V.
Abstract:: The need for clean and renewable fuel such as hydrogen is driven by a growing worldwide population and increasing air pollution from fossil fuels. One of the major barriers for the use of hydrogen in automotive industry is the storage of hydrogen. Physisorption is the most promising storage technique due...

Experimental Characterization of a Supercritical Carbon Dioxide Microchannel Solar Thermal Receiver

Creator:: L'Estrange, Thomas
Abstract:: Characterization of a microchannel solar thermal receiver for supercritical carbon dioxide (sCO₂) is presented. The receiver design is based on conjugate computational fluid dynamics and heat transfer simulations as well as thermo-mechanical stress analysis. Two lab scale receivers with a 2x2 cm² absorber area are fabricated and experimentally characterized -...

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...

Finite volume method modeling of corona discharge microreactor oxidization of dibenzothiophene

Creator:: Fan, Xiangru
Abstract:: The growing need for cleaner fuels requires the development of better deep fuel desulfurization methods. The current study presents a reaction model for the mechanism of dibenzothiophene oxidization by dissolved oxygen occurring in a corona discharge microreactor. In the present work, a Finite Volume Method model of the reactor is...

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...

Applications of Nonthermal Microplasmas in Chemical Reaction Engineering

Creator:: Kreider, Peter B.
Abstract:: Nonthermal plasmas generate high concentrations of excited species that can simultaneously exist at high energy and far from thermodynamic equilibrium, making them useful tools in chemistry and engineering. Microplasmas, roughly defined as plasmas that are generated within sub-millimeter dimensions, provide enhanced stability, improved excited species density, increased nonequilibrium properties, higher...

Micro-bubble dynamics in two-phase flow through a micro-channel

Creator:: Shepard, Thomas G.
Abstract:: An experimental investigation into the behavior of micro-bubbles flowing through a micro-channel has been conducted. Experiments were performed within a rectangular micro-channel with dimensions of 5 cm x 13.2 mm x l30 jim. Bubbles were generated in an electrolyte solution by electrolysis at the lower channel wall near the inlet....

Micromixer assisted continuous flow synthesis of nanoparticles of binary compounds and their application

Creator:: Palanisamy, Barath
Abstract:: In this work, continuous synthesis routes for binary nanoparticles using advantages of microchannel mixing (low diffusion distances and higher mass transfer) and fast heating rates provided by ultrasound induced heating are investigated. In addition, the application of silica nanoparticles in anti-reflective coatings on glass and understanding the structure property-performance correlation...
