The Role of Oxygen In the Stability of Biomass Pyrolysis Oils

Oct 18, 2011
Foster Agblevor
One of the major challenges in the conversion of biomass pyrolysis to high value products and fuels is the poor stability of the oils. Biomass pyrolysis oils have shown increases in viscosity during storage at ambient conditions and when heated above ambient temperature. The poor stability of the...

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...

The Capture of Carbon Dioxide by Ionic Liquid

Oct 18, 2011
Hongyan He
Ionic liquid is one kind of organic salts with negligible volatile pressure which might lead to promising substitute candidates for alkanolamines in separation of carbon dioxide. To satisfy this requirement effectively, task specific ionic liquids with alkaline groups, such as imidazolium cation...

An Integrated Lipid-Based Platform for “Drop-In” Fuel Biorefinery

Oct 18, 2011
Shulin Chen
A major challenge in developing biorefinery is that the availability of biomass often limits the scale of the plant thus the feasibility of an operation. We proposed an integrated lipid-based platform as one technical option. According to this concept, different biomass resources will be first...

Reducing Process Complexity for Cellulosic Ethanol

Oct 18, 2011
L.O. Ingram
Much of the process complexity and high capital costs associate with cellulosic ethanol (dilute acid hydrolysis as a pretreatment and enzymatic saccharification of cellulose) results from side products such as furfural, acetate, and soluble lignin compounds that inhibit the biocatalysts. Inhibitor...

Study on the Pyrolysis Characteristics of Biomass Compositions in Medical Wastes DENG Na * , Wang Weiwei, ZHANG Yu-feng, MA Hong-ting (School of Environmental Science & Engineering, Tianjin Uninversity, Tianjin 300072, China) Abstract: To obtain pyrolysis characteristics of biomass compositions...

Phase-Changing Absorbents for CO2 Capture

Oct 18, 2011
Sarah Genovese
A process to capture CO 2 from flue gas using a liquid material that reacts rapidly with CO 2 to form a solid offers many advantages over conventional liquid-only CO 2 capture methods. The net CO 2 capacity of the system will be increased, the overall system size will be decreased, and the energy...

Biomimicry of the Fungal Consolidation of Biomass Pretreatment with Saccharification

Oct 18, 2011
Justin T. Kaffenberger
Efficient breakdown of ligno-cellulosic material prior to fermentation for bio-fuel production is a key step in optimizing bio-fuel production. Current industrial practice involves chemical pretreatment and acid or enzymatic saccharification to prepare ligno-cellulosic biomass for fermentation. The...
