  • Modeling the conversion of glucose to hydroxymethylfurfural

    Creator:
    Liu, Daming
    Abstract:
    Cellulosic biomass materials have three principal components: cellulose, hemicellulose, and lignin. Under mild acid conditions and high temperature, the first two components yield a variety of sugars: hexoses and pentoses, which are subject to decomposition on continued exposure to hot dilute acid. In the process hexoses yield hydroxymethylfurfural (HMF) which,...

  • Iron oxidation by Thiobacillus ferrooxidans

    Creator:
    Kang, Sun Ki
    Abstract:
    The bacterium most frequently used in microbial leaching processes and studies is Thiobacillus ferrooxidans. Applications of this bacterium include the treatment of coal, low-grade ores and industrial solid wastes for the solubilization of pyrite and other trace metals associated with sulfides. The goal of this study was the development of...

  • Modeling the conversion of arabinose to furfural

    Creator:
    Yasuda, Dean D.
    Abstract:
    Hemicellulose hydrolyzate contains many carbohydrate fractions, the most abundant being xylose, arabinose, and glucuronic acid. Under mild acid conditions (0.025 - 0.10 M sulfuric acid) and high temperatures (140°C to 200°C) the first two components form furfural through a series of dehydration reactions. Unlike xylose and arabinose, glucuronic acid must...

  • Periodate oxidation of cellulose - a complete kinetic study

    Creator:
    Chandan, Bhaskar Arjundev
    Abstract:
    The effect of over-oxidation on periodate oxidation of cellulose was studied. It was found that the over-oxidation process has a significant effect on the overall reaction. An integrated rate equation was formulated. The oxidation of internal glucose units is second-order overall, first order with respect to both periodate and cellulose;...

  • Temperature effects on surface energetic parameters evaluated at solid/liquid interfaces

    Creator:
    Lee, Euisang
    Abstract:
    Measurable surface parameters which may be related to the response evoked upon contact with biofluids have been suggested to provide direction for characterization, prediction, and ultimate control of biofluid behavior at interfaces. With respect to fouling of heat exchange equipment by biofluids, such properties may be useful for the development...

  • Bioleaching of coal in a fluidized bed

    Creator:
    Knott, John A.
    Abstract:
    Illinois coal ground to 80-200 mesh was leached with a low phosphate, high nitrogen medium containing a mixture of Thiobacillus ferrooxidans and thiooxidans in a fluidized bed. Coal slurries of 20-160 g/L were treated in a 5 cm ID, 9.5 m high continuous loop bioreactor with crossovers at top and...

  • Bedrock geology and structure of the Murderers Creek Area, Grant County, Oregon

    Creator:
    Stockman, Alan Owen
    Abstract:
    The Murderers Creek Area, within the Aldrich Mountain province of northeast Oregon, originated in an arc-trench gap during Permian-early Triassic time. The area represents a small portion of a forearc depositional basin and tectonic highland which borders the basin along its seaward margin. The trench associated with an east dipping...
