The aim of this work is to develop a deeper understanding of the nuances involved in designing and optimizing the performance
of gas/liquid plasma reactors for chemical synthesis. The design of such reactors requires integrating knowledge from a number of
scientific disciplines including mechanical engineering (reactor construction), electrical engineering (power network design and
electrical diagnostics), physics (plasma formation and diagnostics), chemical engineering, (reactor design, transport phenomena /
modeling), and chemistry (chemical analysis). Due to the complicated nature of such a multidisciplinary study, complete analysis of a
single reactor system is difficult and rarely performed with accuracy, especially for a variety of operating conditions. In this work, a
novel continuously flowing liquid film plasma reactor was developed and fully characterized under the above criteria for a range of
operating conditions in order to better understand which variables most significantly impact the generation of hydrogen peroxide from pure
water and argon gas. This work shows that increases in the energy yield for hydrogen peroxide with pulsed plasma discharge is possible by
variation of the plasma properties to reduce the amount of "wasted" energy which does not contribute to desired chemical reactions. In
addition, increases in the production rate of hydrogen peroxide without a loss in energy yield is shown to be possible by increasing the
pulse frequency while simultaneously decreasing the gas phase residence time. The high concentration of hydroxyl radicals produced by this
system was also used to partially oxidize simple organic compounds into higher value products. / A Dissertation submitted to the Department of Chemical and Biomedical Engineering in partial
