Some processes aimed to biofuels production, use lignocellulosic wastes as feedstocks for fermentative conversion. If this is the case, pretreatment is required to make these resources fully digestible. Among a wide range of pretreatment options, this study focuses and compares oxidative-alkaline...

Hydrogen-Bromine Flow Battery for Large-Scale Electrical Energy Storage

Oct 17, 2011
Trung V. Nguyen
Abstract Renewable energy, including wind and solar, could supply a significant amount of electrical energy in the United States and around the world. However, despite the benefits of wind and solar, integration of these intermittent sources into the electrical grid system poses major challenges to...

Fischer Tropsch Synthesis Via Biomass Derived Synthesis Gas

Syed Ali Gardezi
Due to the recent surge in energy costs and uncertainties in fuel prices, there is significant interest in seeking alternative sources of energy particularly from renewable such as biomass. Indirect liquefaction of biomass (via the thermo-chemical conversion to syngas followed by liquefaction via...

High Energy Density Lithium Flow Battery Design

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...

Anisole and Guaiacol Deoxygenation Over Pt/Sn On Monolith Catalyst Supports

Oct 17, 2011
Miguel Angel Gonzalez Borja
Upgrading of pyrolysis oil vapors requires a catalytic reactor able to treat high reactant flow rates without generating a large pressure drop. Therefore, monolithic catalysts appear as good candidates for this purpose. In this contribution, low-surface-area Inconel monoliths were coated with in-...

Wood Pellets Self-Heating During Storage

Oct 17, 2011
Wendi Guo
Accidental fires in wood pellets silos happen frequently in the last five years. Experiments were carried out in this work at temperature range of 100 o C to 200 o C to study wood pellets chemical oxidation process. A self-heating model was developed to simulate the self-heating process using the...
