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. This glycerin can be used...
The design & construction of a proton microprobe using a GE PETtrace cyclotron
(University of Missouri--Columbia, 2012)
internals. Unfortunately, there are very few facilities where extreme fast neutron fluences, approximately 300 displacements per atom, can be reasonably achieved. Research at the University of Missouri Research Reactor (MURR) Cyclotron has focused...
The continuous supercritical water gasification of spirulina and the use of a positive displacement feeding system
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] A factorial experiment was designed and conducted to explore the effect of three variables, concentration, temperature, and residence time, on two responses, gasification...
Biodegradable packaging for corrosion inhibition via supercriticial fluid
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The focus of this study is to develop a packaging material that is both biodegradable (BD) and provides corrosion protection for a packaged metal substrate. In this study...
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...
The kinetics of non-catalyzed supercritical water reforming of ethanol
(University of Missouri--Columbia, 2008)
point, 374[degrees]C and 22.1 MPa, and exhibits both liquid and gas-like properties and acts a non-polar solvent. Since supercritical water is denser than steam, supercritical water reactors have the potential of being smaller than their catalytic...
Technology for restarting molten salt nuclear fuel chemistry at MU
(University of Missouri--Columbia, 2011)
-aqueous electrochemical means of separating constituents is gaining attention. In the 1990's, the University of Missouri (MU) performed molten chemical experiments on mixed lanthanide and actinide systems appropriate for the separation of species known to be encountered...
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 ...
Air permit for the construction and operation of a calcium carbide manufacturing plant
(University of Missouri--Columbia, 2010)
