Conversion of glucose to hydrogen gas by supercritical water in a microchannel reactor

Creator:: Goodwin, Aaron K.
Abstract:: Glucose was gasified in supercritical water within a microchannel reactor at 650°C 750°C, and 250 bar to yield H2 rich gas with a low concentration of CO. The feed glucose concentration was 0.1 M. Two microchannel reactor configurations were tested at fluid residence times ranging from 0.5 sec to...

Uptake and metabolism of polycyclic aromatic hydrocarbons by the marine alga Acrosiphonia coalita

Creator:: Christensen, Kristi
Abstract:: The purpose of this research was to examine the ability of the cold water, green, marine, macroalga Acrosiphonia coalita to take up and metabolize polycyclic aromatic hydrocarbons (PAH) from seawater. Axenic suspension tissue cultures of the alga were contacted with seawater containing PAH in sealed experimental vessels. Uptake time courses...

Conversion of biomass constituents to hydrogen-rich gas by supercritical water in a microchannel reactor

Creator:: Goodwin, Aaron K.
Abstract:: Microreactors offer high rates of heat transfer able to intensify highly endothermic biomass reforming reactions in supercritical water. In this study, two continuous flow microreactor configurations were used to gasify biomass constituents in supercritical water. The first reactor configuration was a micro diameter stainless steel or Hastelloy tube (508 µm...

Two-stage photobioreactor cultivation for enhancing lipid production from diatom cells by controlled silicon limitation

Creator:: Rosenberger, Jennifer L.
Abstract:: There is significant interest in utilizing microalgae as a source for biofuels. Diatoms are a class of single-celled microalgae which make silica cell walls and require dissolved silicon as a substrate for cell division. Manipulation of soluble silicon delivery to the culture offers a route to control cell cycle and...

Initial velocity analyses of milling effects on rates of enzyme-catalyzed saccharification of native wheat straw

Creator:: Nguyen, Quynh M.
Abstract:: There is considerable interest in developing environmentally friendly processes for the economical conversion of biomass plant material to biofuels, bioproducts and biomaterials. One approach to such a conversion process is to make use of enzymes for the conversion of plant polysaccharides to simple sugars; the simple sugars could then be...

Evaluation of feedstocks for cellulosic ethanol and bioproducts production in the Northwest

Creator:: Miller, Wesley C. (Wesley Clair)
Abstract:: Cellulosic ethanol production for transportation fuel is one source to help satisfy the increasing worldwide demand for energy and depletion of the fossil fuel supply. Evaluating potential production from plants and waste in Oregon, Washington and Idaho is the purpose of this study. Reed Canary grass, Annual Ryegrass, wheat straw,...

Evaluating the rates of nitrate removal for a nitrate containing, low organic carbon wastewater interacting with carbon-containing solid substrates

Creator:: Hart, Jeffrey L.
Abstract:: The primary objective of this study was to evaluate the rates of nitrate removal for a nitrate containing, low organic carbon wastewater interacting with four different carbon-containing solid substrates (alder woodchips, corn silage, manure and woodchip biochar). Batch systems were tested for nitrate removal, and systems with a combination of...

Science and efficacy of mild sodium hydroxide treatments in enzyme-based wheat straw-to-glucose processing

Creator:: Sophonputtanaphoca, Supaporn
Abstract:: The work described in this dissertation focused on chemistry related to the use of aqueous sodium hydroxide as a treatment in the processing of wheat straw. A major emphasis was the comprehensive evaluation of straw component partitioning due to sodium hydroxide (NaOH) processing. This was evaluated over a range of...

Wheat lignin as a functional dietary fiber component

Creator:: Junyusen, Tiraporn
Abstract:: This dissertation has focused on lignin byproducts that result from the alkali processing of wheat straw. The first study evaluated the application of “standard” lignin quantification methods for summative analyses of alkali-based processes. Mass closure during NaOH processing at 25, 50, and 75°C of wheat straw was evaluated using the...

Life Cycle Assessment of Biomass for Generation of energy : Case Studies of Poplar Management in the Pacific Northwest of the U.S.A.

Creator:: Vasquez Sandoval, Marcia A.
Abstract:: A Life Cycle Assessment (LCA) of the production of poplar biomass grown under four management conditions in the Pacific Northwest (PNW) of the U.S.A. was conducted. While the extraction of fossil fuels and the subsequent generation of energy have environmental impacts, the alternative of extracting poplar biomass also has impacts...
