Life cycle assessment of algal biofuels

Creator:: Kirby, Bryan L.
Abstract:: This thesis consists of three studies to better understand the environmental sustainability potential for algal-based biofuels. Initially, a comparison of recent life cycle assessments (LCA) of theoretical full-scale algal biofuel facilities was developed. These studies include varying boundaries and scope, functional units, and technology maturity assumptions. The comparison converted results...

An Investigation into the Production of Longer Hydrocarbons, Synthesis Gas, and Ammonia via a Nonthermal Plasma Microreactor

Creator:: Reddick, Ian T.
Abstract:: Nonthermal electrical plasmas can allow energy intensive reactions to occur without the use of high operating temperatures or pressures. This is because the collisions of electrons accelerated through an electric field with molecules is the cause of reactions as opposed to thermal collisions between molecules. In this study, the production...

Investigation of the Effect of Pulsed Direct Current on Methane Conversion and Reforming in a Point-to-Point Plasma Discharge Microreactor

Creator:: Shareghi, Adam E. L.
Abstract:: Stranded natural gas and biogas comprise a vast energy resource that is mostly wasted via flaring. This represents an opportunity to investigate novel ways to harness this resource. Nonthermal plasmas consist of excited electrons, ions and neutral atoms/molecules that have the ability to disrupt chemical bonds at ambient temperatures and...

Estimation of momentum, heat and mass transfer in laminar boundary layers

Creator:: Myers, Gary Allen
Abstract:: Sisson's formally exact series solution for momentum, heat and mass transfer in steady two-dimensional or axi-symmetrical constant-property, laminar boundary layer flow was examined. A new series was proposed for the boundary condition accounting for the mass transfer at the surface of the body on which the boundary layer is formed....

A mathematical model for differential thermal analysis

Creator:: Kaakinen, J. W.
Abstract:: A mathematical model of a differential thermal analysis (DTA) system was formulated so that influence of the various physical parameters on the DTA peak could be determined. The specific DTA apparatus simulated had cylindrical sample holes drilled into a nickel block considered to have a negligible thermal resistance, and the...

Modeling large temperature swings in heat regenerators using orthogonal collocation

Creator:: Kokron, Carlos J.
Abstract:: This thesis examines the transient performance of packed bed heat regenerators when very large temperature differences are involved. The effects of gas temperature on the key gas physical properties of velocity, density and heat capacity were studied via simulation. Three models were developed and compared. The first model (HRKDV) considers...

Removal of E. coli with alternative media Biosand filters

Creator:: Fulton, Nathan J.
Abstract:: When Biosand filters cannot be constructed with crushed quarry rock due to resource limitations, a suitable alternative filter media is needed. In this research, two crushed quarry rock alternatives were examined. Three bench-scale Biosand filters with crushed rock, beach sand, and heat-treated beach sand media were simultaneously dosed with Willamette...
