Prediction of Post-Relaxation Radial Tensile Strength of Pharmaceutical Tablets Using At-Line Collected near Infrared Data

Oct 31, 2012

Sameer Talwar

The prediction of relaxed radial tensile strength (RTS) of pharmaceutical tablets in real-time using near infrared (NIR) spectroscopic data collected at-line was investigated. Radial tensile strength is a critical quality attribute (CQA) of tablets which may correlate to drug product performance in...

CFD Modeling of Commercial-Scale Entrained-Flow Coal Gasifiers

Oct 31, 2012

Jinliang Ma

Optimization of an advanced coal-fired integrated gasification combined cycle system requires an accurate numerical prediction of gasifier performance. Computational fluid dynamics (CFD) has been used to model the turbulent multiphase reacting flow inside commercial-scale entrained-flow coal...

Fractionation and Characterization of Lignin From Wood Biomass Using Ionic Liquid and Alkaline Ethanol Solvent

Oct 31, 2012

Yong-Chang Sun

Lignocellulosic biomass is a new source of renewable and carbon neutral materials for biofuel and bioenergy production. However, we note the recalcitrance of lignocellulosic for bioconversion. The presence of lignin is a barrier to enzymatic hydrolysis of cellulose by cellulases, as well as...

Electrochemistry and Transport Limitations of Non-Aqueous Li-Air Batteries From First-Principles

Oct 31, 2012

Venkatasubramanian Viswanathan

Li-air batteries have much higher gravimetric energy storage density compared to all other battery chemistries, and this has led to a strong interest in seeing if such batteries could be developed for powering EVs, enabling driving ranges comparable to gasoline powered automobiles. However, many...

Aspen Simulation of Mobile Biomass to Liquid Facility – the Beauti-Fuel Concept

Oct 31, 2012

Xinying Liu

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...
