The BeauTi-fueL facility is a mobile biomass to liquid facility, where the key equipment of the biomass to liquid process is placed into a commercial container and can be transported to a biomass site for liquid fuel production. This facility can be used to process the biomass such as agriculture...

Aeration Induced pH Elevation of Anaerobically Digested Wastewater for Enhanced Ammonia Stripping and Recovery

Oct 31, 2012

Craig Frear, Quanbao Zhao

During mesophilic or thermophilic anaerobic digestion, a considerable fraction of organic nitrogen is mineralized to ionic ammonia, producing an effluent with higher concentrations of ammonia nitrogen as well as elevated temperatures, both of which can be useful in dowstream processing of ammonia...

Application of Quality by Design in API Process Development

Oct 31, 2012

Nirav Shah

Design of Experiments (DOE) is the most effective method to achieve product and process efficiency and optimization. Design of Experiment (DOE) studies can help develop process development knowledge by revealing relationships, including multifactorial interactions, between the variable inputs (e.g...

In -Situ Precipitation of CaCO3 within Pulp Fibers Enhances Optical and Printing Properties of Paper

Oct 31, 2012

Surendra Pal Singh

Writing and printing papers are usually loaded with white pigment particles to improve many paper properties such as light scattering, smoothness, pore-size distribution, and ink-paper interactions. In the conventional method of loading, the filler particles are added directly into the papermaking...

Production of Hydrogen and Nanocarbon From Catalytic Decomposition of Methane Over a Ni-Fe/Al2O3 Catalyst

Oct 31, 2012

Yongdan Li

Methane catalytic decomposition reaction (MCD) has received much attention in recent years as a potential route for the direct production of COx (CO/CO 2 )-free hydrogen because of its environmentally benign, energy efficient and process simple characteristics, which produces an especially suitable...

Development and Performance Evaluation of a Cost-Effective Oxygen Carriers

Oct 31, 2012

Liangyong Chen

Chemical looping combustion (CLC) for power generation has the inherent potential of enriching CO 2 from flue gases in-situ with low energy penalty compared to other commercial available options. However, the feasibility of applying CLC to burning coal is heavily depended on the suitability of...

Effects of Farm Wastes Co-Digestion On Microbial Community, Methane Production, and Fiber Quality As Biorefining Feedstock

Oct 31, 2012

Rui Chen

The performance of anaerobic digestion is highly correlated to the compositions of its substrate and microbes. A lab-scale anaerobic digestion process of a mixture of dairy manure and corn stover in continuous stirred-tank reactor (CSTR) was performed to investigate the influence of additional...

Simulation of Methane Steam Reforming Enhanced by in Situ CO2 Sorption Utilizing K2CO3 Promoted Hydrotalcites for H2 Production

Oct 31, 2012

Naruewan Chanburanasiri

The motivation to switch the fossil fuels to an alternative fuel is an emerging area of research and development during the past decade. Hydrogen is a clean energy carrier for sustainable consumption that can be used in various goals such as raw materials in ammonia and methanol manufactures as...

5-HMF Production in Piperylene Sulfone: A Bifunctional Solvent for Reaction and Separation

Oct 31, 2012

Christopher J Butch

5-Hydroxylmethylfurfural has garnered wide interest as a potential bio-based commodity chemical due to its multiple reactive groups and relatively easy formation from fructose and other sugars. For example HMF can be produced from fructose in DMSO in high yields; however the separation is difficult...

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...
