Kinetics Study of Calcium Carbonate Decomposition At High CO2 Environment

Oct 17, 2011
Jian Zhang, Yong Min
With the concerns of “global warming”, CO2 sequestration from cement industry are becoming significant important for the “green processing” for the environments. This is because the cement processing released about 36% of CO2 comparing to the 12% from regular coal-power plant. CaO/CaCO3, a major...

Highly Active Oxide Photocathode for Photoelectrochemical Water Reduction

Oct 17, 2011
Elijah Thimsen
A clean and efficient way to overcome the limited supply of fossil fuels and the greenhouse effect is the production of hydrogen fuel from sunlight and water through the semiconductor/water junction of a photoelectrochemical (PEC) cell, where energy collection and water electrolysis are combined...

Effect of Pressure and Heating Rate On Biomass Devolatilization and Gasification

Oct 17, 2011
Pradeep K. Agrawal
The goal of present study is to characterize the effect of pressure and heating rate on the devolatilization behavior of different biomass species. Three biomass species (southern Pine, corn stover, and switchgrass) were studied. A combination of two complementary gasification devices are utilized...

Investigation of CuO-Based Oxygen Carriers As CLOU Materials for Solid Fuels

Oct 17, 2011
Mehdi Arjmand
Chemical-looping combustion (CLC) is a promising combustion technique with efficient CO 2 -capture at low cost due to inherent gas separation. In a CLC process, a metal oxide is circulated between two reactors, wherein they undergo changes from an oxidized form in the air reactor to a reduced one...

High Energy Density Lithium Flow Battery Design

Oct 17, 2011
Galen Suppes
Traditional sandwich cell battery chemistries are used in a flow cell where a pump circulates fluid between electrodes through a permeable membrane. The energy densities of these batteries are many fold higher than flow batteries where one or more reagent is stored in the electrolyte. Side-by-side...
