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...

Hydrogen Production From Deliquescence of Ammonia Borane

Oct 18, 2011
Bing-Hung Chen
Chemical hydride is one of the most potential hydrogen storage materials which can effectively increase hydrogen storage capacity. To meet the new goal of U.S. department of energy (DoE), 4.5wt% and 5.5 wt% of gravimetric hydrogen density capacity by 2010 and 2015, respectively, ammonia borane (AB...

Structural Characterization of AHP-Pretreated Biomass

Oct 18, 2011
Muyang Li
Alkaline hydrogen peroxide (AHP) pretreatment is exceptionally well-suited to grasses, yielding high digestibilities at low enzyme loadings, while generating relatively few fermentation innhibitors. For AHP pretreatment, the question of how structural and chemical compositional changes within the...

Accelerated Thermal Decomposition of Ammonia Borane by Carbon Dioxide

Oct 18, 2011
Junshe Zhang
This talk presents the enhanced dehydrogenation of ammonia borane (AB) at 85 o C under CO2, an abundant and naturally occurring material. The presence of CO 2 significantly accelerates the thermal decomposition and it kinetics becomes faster as the CO 2 pressure increases from 1.70 to 3.67 bar...

Comparison of Chemical and Biological Delignification of Cardboard

Oct 18, 2011
Estefania Isaza
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...
