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 ...
Gas phase conversion of sugars to C3 chemicals
(University of Missouri--Columbia, 2008)
The limited fossil oil reserve, fast-rising crude oil price and increasing environmental concerns make scientists and researchers give a serious look at biomass as feed stocks to produce chemicals and fuels. Five chapters ...
Catalytic conversion of glycerol and sugar alcohols to value-added products
(University of Missouri--Columbia, 2006)
The current research is based on developing an improved and fundamental understanding of technology that will allow the conversion of this crude glycerin to a propylene glycol based antifreeze product. Hydrogenolysis of ...
Use of enzymes to produce soy-based polyol for polyurethane
(University of Missouri--Columbia, 2006)
Soy-based polyol used in polyurethane applications are sustainable and renewable materials which have been reported to require less energy to produce and to have lower market price. They also have less environmental impact, ...
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 ...
Catalytic conversion of glycerol to propylene glycol : synthesis and technology assessment
(University of Missouri--Columbia, 2006)
This research is focused on developing a method that is applicable to the industrial-scale production of propylene glycol from glycerol with considerably high conversions and yields. The fundamental understanding behind ...
Polyols made from vegetable oil and their applications
(University of Missouri--Columbia, 2006)
In the course of research, soybean oil was polymerized to form bodied soybean oil (BSBO) also termed heat polymerized soybean oil which was used to derive the epoxy bodied soybean oil-hydroxyl value # 193, BSBO/aceto-hydroxyl ...
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. ...
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 ...
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 ...
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 production, applications and economic study of activated carbon for large scale production including an educational study on undergraduate laboratory modules
(University of Missouri--Columbia, 2010)
The production of activated carbon was evaluated using a biomass feed stock, corn cobs, as a precursor. The importance of the carbonization process and activation process are discussed and how nanopores and its unique ...
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 ...
