Development of a Compact Fischer Tropsch Reactor

Oct 18, 2011
Lyman Frost
Fischer Tropsch (FT) synthesis is a polymerization process where a CH X species is added to a growing aliphatic chain. There are several models of the catalytic chain propagation rate and the termination of the chain growth (e.g. Anderson – Schulz – Flory model). The exact methodology for the...

Photoanode Area Dependent Efficiency and Recombination In Dye Sensitized Solar Cells

Oct 18, 2011
Venkat Kalyan Vendra
Current-voltage characterization was carried out on dye sensitized solar cells (DSSCs) with different photoanode areas ranging from 0.01 cm 2 to 1 cm 2 . Surprisingly, we found that the short-circuit current density and the efficiency of the solar cells increased exponentially as the photoaonode...

A-Priori Estimation of Reactive Amino Acid Based Ionic Liquids for CO2 Absorption

Oct 18, 2011
Johannes Voelkl
The separation of CO 2 is an important topic in thermal separation science. The scrubbing of carbon dioxide from exhaust gases has gained more interest in the last years to reduce the emissions of green for counteracting global warming but is also an important process step in biogas upgrade to...

Cellobiose Hydrolysis Using Acid-Functionalized Nanoparticles

Oct 18, 2011
Leidy Peña
Mineral acids have been used effectively for the pretreatment of cellulosic biomass to improve sugar recovery and promote its conversion to ethanol; however, substantial capital investment is required to enable separation of the acid, and corrosion-resistant materials are necessary. Disposal and...

Imidazole and Imidazole-Amine Hybrid Solvents for CO2 Capture

Oct 18, 2011
Jason E. Bara
Imidazoles and imidazole-amine hybrids are unique classes of organic solvents that feature properties similar to aqueous amine solvents and ionic liquids (ILs), both of which have received a great deal of attention for CO2 capture applications. However, to date, the utility of the imidazole...

Ab-Initio Study of Glycerol Dehydration Mechanisms with Explicit Solvent Treatment

Oct 18, 2011
Tim Courtney
Glycerol produced as a waste product in biodiesel production has interesting potential as a low-cost biomass-derived feedstock for chemical processing. A process of current academic and commercial interest is the acid-catalyzed dehydration of glycerol to acrolein, a valuable platform chemical. Such...

Cellulose Extraction From Rice Hulls Using Ionic Liquids

Oct 18, 2011
Charles J. Coronella
Over one fifth of calories consumed by humanity are from rice. Consequently, vast quantities of rice hulls are disposed of as waste, since the hull constitutes 20% of rice mass. Standard practice for disposal of rice hulls is burning, generating pollution and CO 2 , or thrown away in vast...

Production of Synthetic Paraffin Kerosene by Hydrocracking Fischer-Tropsch Wax

Oct 18, 2011
H. Nicholas Conkle
The US Air Force has committed to an alternative aviation-fuel initiative to implement a roadmap for testing and certifying alternative fuel components including biomass-derived alternatives produced from non-food plants, animal fats, and algae, as well as synthetic fuel components derived from...
