Alternative Fuels and Their Effects on Portland Cement

Folta, Aaron (2010-07-19)

The production of portland cement is a complex process involving several materials, complex systems, and temperatures on the order of 1500 °C. Non-renewable fossil fuels such as coal, petroleum coke, and natural gas have ...

Application of Near Infrared Spectroscopy to Pulp Yield and Kappa Number Estimation

Lightle, Roy (2006-08-15)

This thesis presents an investigation into near infrared (NIR) spectroscopy as a technique for determining pulp yield and kappa number for kraft pulp and black liquor samples. It is believed that proper spectra collection ...

Bioconversion of lignocellulose into acetone-butanol-ethanol (ABE): pretreatment, enzymatic hydrolysis and fermentation

Guan, Wenjian (2016-12-09)

Abstract The objective of the present dissertation is to investigate the bioprocess for the production of acetone-butanol-ethanol (ABE) from lignocellulosic feedstocks via ABE fermentation with solvent-producing ...

Development of a Drop Tube Furnace for Visualization of Combustion of Fuel Particles

Huang, Fengming (2010-03-26)

This thesis describes the development of a laboratory-scale burn simulator designed to maximize visualization capability in a combustion furnace with a high degree of control of temperature and particle presence. A ...

Investigation of Mass Transfer Phenomena in Supercritical Antisolvent Precipitation Processes

Chinnawar, Rajeshwar (2015-08-04)

This dissertation involves a detailed discussion of the production of organic and polymeric microparticles of controllable size and size distribution for several applications including certain pharmaceutical formulations. ...

Reaction Analysis of Templated Polymer Systems

Vaughan, Asa (2008-08-15)

Templated polymer systems have unique 'trained' binding characteristics that make them of high interest within chromatography, sensors, diagnostic devices, and drug delivery carriers. In this work, a typical highly ...

Solidification of Hydrocarbon Liquids using Polymer Blends

Solomon Mohanraj, Jola Jayselene (2010-08-03)

Solidifiers are composed of dry, high molecular weight polymers that have a porous matrix and a large oleophilic surface area. They bond with the hydrocarbon liquids by molecular interaction (hydrogen bonding, London forces, ...

Visualization of Chlorella Algal Cells at Bubble Surfaces

Tuin, Stephen (2008-05-15)

This thesis examines flotation as a method for harvesting the green algae chlorella for its use as a feedstock for biofuel. Lipids extracted from algae can be converted to biodiesel for use as an alternative renewable ...

Visualization Studies of Evaporation and Combustion of Alternative Liquid Fuels and Aviation Liquid Droplets in Controllable Environments

Venkatasubramanian, Vignesh (2018-04-24)

This dissertation describes visualization studies of alternative fuel and aviation liquid droplet behavior in controlled environments. Three experimental setups using free-falling and suspended droplet techniques were ...

Wall Heat Transfer Properties of Metal Microfiber Catalyst Support Structures

Gonzalez, Carlos (2015-05-11)

A renewed interest in highly exothermic and endothermic reactions for scalable energy technology have demanded a need for a catalyst support structure that is capable of managing the thermal requirements of the reaction ...
