Dry Reforming of Methane Using Rh Substituted Pyrochlores

Oct 31, 2012

Devendra Pakhare

Dry (CO 2 ) reforming of methane (DRM) to syngas (H 2 and CO) has been well-studied over a number of catalysts. The high temperatures needed to produce syngas inevitably result in carbon formation. Although pyrochlores are known to be thermally stable at conditions required for dry reforming, we...

Recovery of Hydrocarbons From Froth Treatment Tailings of Oil Sand Bitumen Processing

Oct 31, 2012

Yuming Xu

Bitumen is separated from surface-mined oil sand ore in a warm water extraction process that produces bitumen froth typically containing 60 wt% bitumen, 30 wt% water, and 10 wt% mineral solids. The water and solids are then removed from the froth by solvent dilution followed by gravitational...

Novel Ternary and Doped Transition Metal Oxide Oxygen Evolution Electro-Catalysts for Hydrogen Production Via PEM Based Water Electrolysis

Oct 31, 2012

Karan Kadakia

Hallmark of a sustainable world is one wherein energy demands are consistently met with renewable energy sources. In this regards, hydrogen is often touted as the “magic” fuel of the future if it can be derived from renewable systems such as solar energy as the source of electrical potential...

Development of Metal-Oxide-Semiconductor Photoelectrodes for Photoelectrochemical Water Splitting

Oct 31, 2012

Daniel V. Esposito

Photoelectrochemical (PEC) water splitting is a promising pathway for renewable H 2 production, but there remains a great need for improving the efficiency and stability of semiconducting photoelectrodes. One promising approach to achieving high efficiency and good electrochemical stability is the...

Experimental Investigation On the Effects of Trace Contaminants in Coal Derived Syngas On Performance of SOFC Ni-YSZ Anode

Oct 31, 2012

Koji Kuramoto

As an extension of the current RD&D on the integrated gasification combined cycle (IGCC), we could consider the incorporation of high-temperature fuel cell into the coal gasification-based power generation process (IGFC) for further increase of the plant efficiency. To explore the probability...

Dynamic Model of a Solar Thermochemical Water-Splitting Reactor with Integrated Energy Collection and Storage

Oct 31, 2012

Rong Xu

Global climate change is the preeminent challenge of the 21 st century. Carbon dioxide from fossil fuel combustion is altering the world's environments, potentially in undesirable ways. It is critical to develop carbon-free and environmental friendly energy sources. Molecular hydrogen is currently...

Highly Efficient Integrated Chemical Looping Gasification Fuel Cell System

Oct 31, 2012

Liang Zeng

Chemical looping process is designed for indirect reactions between fuel and oxidants via exchanging a stream of oxygen carrier particles among separate reactors. It is a promising process that can effectively increase the exergy efficiency for carbonaceous fuel conversion. The chemical looping...

Using Non-Cl? Containing Ionic Liquids for Rice Hull Pretreatment

Oct 31, 2012

Joan G. Lynam

Rice is the fundamental food for about half the world's population and provides over 20% of calories consumed by humans. Since the rice hull or husk is 20% of the grain, vast quantities of rice hulls are produced worldwide, which are then disposed by either burning, generating pollution and CO 2 ,...

Molten Salt Gasification (MSG) of Refinery Wastes to Produce Hydrogen

Oct 31, 2012

Lyman Frost

Western Hydrogen Limited is developing a process called Molten Salt Catalyzed Gasification (MSG) that allows the production of high-pressure synthesis gas at ~138 bar (~2000 psig) or higher without the need for compression. This makes the process very efficient since the compression of synthesis...

Potential for CO2 Ehanced Oil Recovery in the Appalachian Basin

Oct 31, 2012

Timothy Carr

The Appalachian basin oil and gas producing region has a large amount of oil which will be left in the ground, or “stranded”, following the use of today’s oil recovery practices. A major portion of this “stranded oil” is in mature reservoirs that based on this study appear to be technically...

Inorganic Analysis of HTC Biochar

Oct 31, 2012

M. Toufiq Reza

The increase in greenhouse gas concentration, primarily due to emissions of CO 2 produced in use of fossil fuel, motivates many efforts to identify renewable energy alternatives. Using fuel from food sources is not optimal, since malnourishment is still prevalent in the developing world. Despite...

Hydrogen and Methane Rich Syngas From a Catalytic Coal Gasifier with in Situ Capture of H2S/CO2 and Ex Situ Regeneration of Catalysts

Oct 31, 2012

Nicholas Siefert

We present experimental results from a lab-scale, fixed-bed, catalytic, steam-coal gasifier with in situ capture of H 2 S/CO 2 . While the low-carbon and low-sulfur syngas leaving the gasifier could be sent directly to a gas turbine to generate electricity, the driving force for this research is...

Effect of Storage Time On the Catalytic Activity of Gold for Selective CO Oxidation

Oct 31, 2012

Fabio B. Passos

Gold supported alumina catalysts were studied for selective CO oxidation, in order to provide appropriate H 2 for PEM fuel cell. The catalysts were prepared by deposition-precipitation method using HAuCl 4 as precursor of gold. The catalysts showed high activity at lower temperatures. The fresh...
