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 this glycerol technology...
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 ...
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 in this dissertation...
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 glycerol to propylene glycol...
Chemical modifications to produce soy-based polyols
(University of Missouri--Columbia, 2009)
for further reaction to form polyols in a batch reactor. Two different heat polymerization approaches were studied: non-catalyzed and catalyzed soybean oil using as catalyst. A continuous flow reactor was designed to evaluate and compare with the batch reactor...
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, ...
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 ...
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 ...
