Phase equilibria for the sucrose-potassium chloride-water system on Dowex 50 W X 4 resin (K⁺) at 90⁰C

Creator:: Kalwani, Shantukumar Laxmidas
Abstract:: Equilibrium data for the sucrose-potassium chloride-water system were taken for Dowex 50 W X 4 resin at 90° C. The sugar concentration was varied from 0% to 60% by weight, and the salt content, from 0% to 6% by weight. Because shrinkage of the resin due to salt absorption was...

Solids movement in a tube-filled fluidized bed

Creator:: Deaton, William W.
Abstract:: Mixing of ferrite tracer with silica sand was studied in a 0.91 m x 0.91 m cold fluidized bed. Inductance probes located Inside dummy heat transfer tubes [in a 4 x 4 x 4 array] were used to monitor a ferrite tracer with physical properties similar to coal as it...

Density Functional Theory Investigation of CH Coupling and CH Hydrogenation Reactions on Different Cobalt Surface Facets and Fischer-Tropsch Temperature Swing Reactor Optimization

Creator:: Petersen, Dennis F.
Abstract:: Fischer-Tropsh Synthesis is a chemical process that converts CO and H₂ (syngas) into long stable hydrocarbon chains to use as fuel. This process suffers from large product distribution that requires expensive post processing. In this study, the reaction mechanism of hydrocarbon chain growth on Co is investigated on different surface...

Design Principles of Transition Metal X-ide Catalysts for Electrochemical Oxygen Reduction and Evolution Reactions: In-Situ X-ray Spectroscopy Studies

Creator:: Wang, Maoyu
Abstract:: Hydrogen is the green fuel that can be produced from water through electrolysis and used via hydrogen fuel cells to generate electricity with zero carbon dioxide emission. The commercialization of electrolyzers and fuel cells is the critical step to achieving global carbon neutrality. However, it is severely hampered by the...

Kinetic and equilibrium analysis of metal ion adsorption onto bleached and unbleached kraft pulps

Creator:: Yantasee, Wassana
Abstract:: Most metal ions have negative impacts on pulp mill operations. The concentrations of metal ions on pulp fibers and in washwaters rise significantly with increased wastewater recycling. The development of technology to remove these metal ions requires an understanding of how metal ions are bound to pulp components. It is...

The effect of copolymer and iron on the fouling characteristics of cooling tower water containing corrosion inhibitors

Creator:: Abu-Al-Saud, Abdullah A.
Abstract:: Various antifoulant treatment programs and the considerations necessary for the effective use of such programs were examined. Two different groups of tests, with and without iron contamination, have been carried out on the effectiveness of several of the state-of-the-art copolymers (PA, HEDP, AA/HPA, AA/MA, SS/MA and AA/SA) in the inhibition...

Uptake and metabolism of the explosive RDX by the marine seaweeds Portieria hornemannii and Acrosiphonia coalita, and uptake of the explosive TNT by algal extracts of Portieria hornemannii

Creator:: Weber, Ryan A.
Abstract:: This study examines the interactions between explosive environmental contaminants and marine seaweeds. The scope of this thesis includes studies done on the explosive RDX with tissue cultures of marine seaweeds, as well as studies on the explosive TNT with seaweed extracts. The ability of two different marine species of macroalgae...

Remediation of heavy-metal contaminated soils using succinic acid

Creator:: Kaul, Arvind
Abstract:: Succinic acid, a low molecular weight dicarboxylic acid was used to leach out heavy metals from Willamette Valley soil (contaminated separately with lead, copper, and zinc) in form of water-soluble organo-metal complexes. The research tasks included developing synthetic contaminated soils representative of those found at Superfund sites and making heavy...
