Deep eutectic solvents extraction of dibenzothiophene in model diesel
(University of Missouri--Columbia, 2017)
Organic sulfur compounds in diesel fuel produce SOx during combustion in vehicles, leading to severe environmental pollution and causing health issues. The U.S. Environmental Protection Agency has established increasingly ...
Preparation and characterization of bioadsorbent beads for removing selected heavy metal ions from wastewater
(University of Missouri--Columbia, 2018)
Rapid industrialization is one of the major threats to water pollution worldwide, as discharge effluents contain large amounts of toxic metal ions. Heavy metals are highly toxic to the ecosystem and human even at very low ...
Supercritical extraction of binder from multilayer ceramic capacitors
(University of Missouri--Columbia, 2008)
Supercritical extraction using carbon dioxide was carried out in a semi-continuous mode on the binder and its components of an acrylate-based system, the results of which were compared with a poly (vinyl butyral)-based ...
Developing, implementing, and assessing coupled-tank experiments in an undergraduate chemical engineering curriculum
(University of Missouri--Columbia, 2009)
Five experimental modules that fit into the Undergraduate Chemical Engineering Curriculum were developed using the existing Coupled-Tank Apparatus. Students of different educational levels get an opportunity to develop ...
Failure analysis of green ceramic bodies during thermal debinding
(University of Missouri--Columbia, 2009)
In industry, thermal debinding is the traditional mode of binder removal from multilayer ceramic capacitors (MLCs). Binder removal from ceramics takes as long as 50-150 h, thereby contributing significantly to the manufacturing ...
Production, characterization, and applications of activated carbon
(University of Missouri--Columbia, 2010)
This thesis investigates the production of activated carbon, an environmentally friendly adsorbent which is used in many industries. Activated carbon can be derived from many different sources and produced in varying ...
Chemical modifications to produce soy-based polyols
(University of Missouri--Columbia, 2009)
This project comprises several chemical routes to produce soy-based polyols for future use in polyurethane foam applications. Soybean oil was polymerized by heat and catalyst to increase molecular weight, and viscosity for ...
Validation and insight into a novel packed-bed electrode flow battery architecture
(University of Missouri--Columbia, 2010)
In order to improve upon current flow battery technology and to obtain higher specific energies, a novel packed-bed electrode flow battery (PBEFB) is proposed. The validation of the use of packed-bed electrodes in a flow ...
The kinetics of non-catalyzed supercritical water reforming of ethanol
(University of Missouri--Columbia, 2008)
Agriculturally produced ethanol, a renewable resource, may be reformed noncatalytically into hydrogen by a novel process utilizing supercritical water, which acts synergistically both as a solvent and as a reactant. By ...
Synthesis and testing of soy-based polyols : phosphate and glycerolysis oligomers
(University of Missouri--Columbia, 2009)
Soy-based polyols are important industrial prepolymeric materials that use renewable resource. They react with isocyanates to produce polyurethanes (PU) and can be produced at costs less than polyols derived from petrochemicals. ...
Flammability characterization of fat and oil derived phase change materials
(University of Missouri--Columbia, 2005)
Phase change materials are a quickly growing commodity in a world which now places a premium on energy conservation, and renewable energy sources. The implementation of PCMs into several world markets can lead to reduced ...
Equilibrium limitations and selectivity on conversion of glycerol to propylene glycol
(University of Missouri--Columbia, 2006)
Hydrogenolysis of glycerol to propylene glycol was performed at lower temperatures and pressures using concentrated glycerol. Reactions were carried out at 180, 200, 220, and 240⁰C and at a system pressure of 1, 2, and 4 ...
Nanoporous carbon from corn cobs and its application
(University of Missouri--Columbia, 2007)
Chemical activation of corn cobs using phosphoric acid or potassium hydroxide can lead to nanoporous carbon having surface area in excess of 3800 m²/g and pore volume of 2.5cc/g. Dried, crushed, corn cobs were carbonized ...
Synthesis, characterization and applications of fats and oil derived phase change materials
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Phase Change Materials (PCM) are materials that absorb or release relatively large amounts of latent heat and are termed as "latent" thermal storage ...
Permeability analysis for thermal binder removal from green ceramic bodies
(University of Missouri--Columbia, 2007)
The permeability of unlaminated and laminated green tapes was determined as a function of binder content for binder removed by air oxidation. The tapes are comprised of barium titanate as the dielectric, and polyvinyl ...
Production of propylene oxide from propylene glycol
(University of Missouri--Columbia, 2007)
The primary goal of this research was to find a renewable synthesis method for the production of propylene oxide. Significant quantities of glycerin are formed as a co-product when soybean oil is used to produce bio-diesel. ...
Biodegradable packaging for corrosion inhibition via supercriticial fluid
