Comparison of Amine-Based Absorbents for Post-Combustion Carbon Capture

Oct 18, 2011

Sumedh S. Warudkar

As a part of this work, we have performed a comparison of 4 amine-based absorbents using the process simulation software ProMax ® with TSWEET ® . Absorbents were compared at pulverized coal fired power plant flue gas conditions. The criteria for comparison of absorbents are the energy requirement...

Kinetics of CO2 Absorption Into Aqueous Potassium Carbonate Solution Promoted by Carbonic Anhydrase Enzyme

Oct 18, 2011

Xinhuai Ye

A novel Integrated Vacuum Carbonate Absorption Process (IVCAP) for post-combustion CO 2 capture is being developed at the University of Illinois at Urbana-Champaign. A key technical aspect of this process is to employ a biocatalyst, carbonic anhydrase (CA) enzyme, to enhance the rates of CO 2...

Mechanistic Investigation of Drug Release From Asymmetric Membrane Tablets

Oct 18, 2011

Mary T. am Ende

An asymmetric membrane (AM) tablet was developed for a soluble model compound to study the in vitro drug release mechanisms in challenge conditions, including osmotic gradients, concentration gradients, and under potential coating failure modes. Porous, semipermable membrane integrity may be...

A New Metal-Decorated Carbon Catalyst for Dehydrogenation of Complex Hydride Hydrogen Storage Materials

Oct 18, 2011

Sean S.-Y. Lin

In recent years, many new solid-state hydrides with a high hydrogen capacity that meet DOE requirement (> 7.5 wt.% H 2 ) have been synthesized as promising on-board hydrogen storage materials. In these hydrides, however, only a small fraction of hydrogen can be released at a desired on-board...

Catalytic Isomerization/Dehydration of Sugars On Functionalized CNT-Metal Oxide Hybrids At the Liquid-Liquid Interface of Water/Oil Emulsions

Oct 18, 2011

Jimmy A. Faria

The conversion of C5-C6 sugars into 2-furfural (FA) and 5-hydroxymethylfurfural (HMF) have been considered as key intermediate step in the production of transportation fuels and chemicals from ligno-cellulosic biomass. Typically, the process involves the dehydration reaction of the sugars catalyze...

CMC Reviewer Expectations for ANDAs Using QbD Approaches

Oct 18, 2011

Robert L. Iser

There has been an increase in science and risk-based approaches under the Quality by Design paradigm in new drug submissions to the FDA. There are particular challenges for generic drug manufacturers with respect to using QbD approaches, especially with more complex dosage forms, such as modified...

Structure and Thermochemistry of Phase-Changing Aminosilicone-Based CO2-Capture Absorbents

Oct 18, 2011

Benjamin R. Wood

Liquid aminosilicone-based CO 2 absorbents that solidify upon reaction with CO 2 have been developed. These phase-changing absorbents have the potential for superior performance for capturing CO 2 from the flue gas of pulverized-coal power plants. A process has been conceived in which the liquid...

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...

Activated Carbon Process for Simultaneous SOx/NOx Removal From Concentrated CO2 At Elevated Pressures

Oct 18, 2011

Monica Zanfir

Background Oxy-combustion is considered as one of the CO 2 capture options for the coal-fired power plants. The CO 2 -rich flue gas from such a plant will have to be compressed and purified for sequestrtion. Praxair is developing a near zero emissions technology that will produce CO 2 virtually...
