A Novel Pulsed-Plasma Catalytic Reactor For Dry Reforming Of Methane, Benjamin F. Caithamer
A Novel Pulsed-Plasma Catalytic Reactor For Dry Reforming Of Methane, Benjamin F. Caithamer
Dissertations, Master's Theses and Master's Reports
Concerns over greenhouse gases have led to an increased interest in the Dry Reforming of Methane (DRM) which produces hydrogen and carbon monoxide from the reaction of two greenhouse gases (CO2 and CH4) over a catalyst. Currently, DRM is primarily a catalytic process which operates at temperatures between 700°C - 900°C, and 10 to 20 bar using a 1–1.5 ratio of CH4/CO2. Unfortunately, these conditions also promote the water-gas shift reaction, which produces additional CO2. Catalyst coking and sintering can also be significant problems at these harsh conditions. We have developed …

Numerical Investigations Of 2-D Magnetic Nozzles On Pulsed Plasma Plumes, Joshua Daniel Burch
Masters Theses
"This research presents studies of a novel type of magnetic nozzle that allows for three-dimensional (3-D) steering of a plasma plume. Numerical simulations were performed using Tech-X's USim® software to quantify the nozzle's capabilities. A2-D planar magnetic nozzle was applied to plumes of a nominal pulsed inductive plasma (PIP) source with discharge parameters similar to those of Missouri S&T's Missouri Plasmoid Experiment (MPX). Argon and xenon plumes were considered. Simulations were verified and validated through a mesh convergence study as well as comparison with available experimental data. Periodicity was achieved over the simulation run time and phase angle samples were …
