A Comprehensive Multi-Step Description of the Permeation of Hydrogen in a Dense Metal Membrane Over a Broad Temperature Range

Oct 30, 2012

Nicholas Deveau, Yi Hua Ma

Development of cheaper and more durable dense metal membranes are being sought for generation of pure hydrogen suitable for fuel cells from coal. Toward this end, we have developed a comprehensive multi-step model for describing permeation of hydrogen in such membranes. The various steps include: s...

Metallic Based Aqueous Amine Membranes for the Separation of Carbon Dioxide From Fossil Fuel Flue Gas

Oct 30, 2012

Brian L. Bischoff

According to the US Department of Energy, there is scientific evidence that CO 2 emissions from fossil fuels have caused climate change and that a reduction of these emissions is essential for reducing the risk of future devastating effects. At present, the leading technology for the post...

Process Synthesis and Global Optimization of Biomass to Liquid Transportation Fuels (BTL) Systems

Oct 30, 2012

Richard C. Baliban

The transportation sector relies heavily on petroleum as a primary energy source, and currently faces challenges over high crude oil prices, volatility of the global oil market, and high levels of greenhouse gas (GHG) emissions [1]. As a result, a substantial effort has been taken in the United...

Proposed Baselines and Standard Methods for Systems Analyses of Power Generation Technologies

Oct 30, 2012

Michael Matuszewski

The Department of Energy's National Energy Technology Laboratory (NETL) routinely conducts analyses of power generation systems in order to guide responsible expenditure of public funding used for the development and demonstration of advanced power generation technologies, especially in the field...

The Solar Thermochemical Reduction of CO2 to CO Via the Heterogeneous Oxidation of Zn(g)

Oct 30, 2012

Luke J. Venstrom

The heterogeneous oxidation of Zn(g) is a promising means of sustainably reducing CO 2 to CO in the two-step Zn/ZnO solar thermochemical cycle. Prior efforts on CO 2 reduction in the cycle have focused on the oxidation of solid or liquid Zn, and elucidate the need for faster kinetics. The rate of...

Inversion of Latent Variable Regression Models to Support Product and Process Development

Oct 30, 2012

Salvador García-Muñoz

When designing a new product and its manufacturing process, there is the need to understand how the raw material properties and the process parameters interact and affect the product performances, in order to control them and optimize the manufacture. For these reasons, usually large amounts of...

Assessing Excipient Variability within QbD Drug Product Development

Oct 30, 2012

Joseph Kushner

Understanding variability in excipient physico-chemical properties is becoming an important aspect of Quality-by-Design (QbD) drug product development. However, present experimental methods are only able to study a few physico-chemical properties on a few excipient lots due to time, cost, and...

Toward a Common Method of Cost Estimation for CO2 Capture and Storage At Fossil Fuel Power Plants

Oct 30, 2012

Edward S. Rubin

There are significant differences in the methods employed by various organizations to estimate the cost of carbon capture and storage (CCS) systems for fossil fuel power plants. Such differences often are not readily apparent in publicly reported CCS cost estimates. As a consequence, there is a...

Thermal Reduction of Magnetically Stabilized Ferrites Under Reduced Pressure

Oct 30, 2012

Nicholas AuYeung

Oxidation of a metal (or metal oxide) by H 2 O and CO 2 followed by a regenerative high temperature thermal reduction of the resulting metal oxide is a promising method for using concentrated solar energy to produce syngas, a precursor for liquid fuels. For such a process to become viable, the...

Oct 29, 2012

Mike Musil

Increasing global demand for green energy has boosted the development of various means of energy generation and storage. Both fuel cells and batteries show big potential for an increasing amount of applications, however they still suffer from various drawbacks. Among others, fuel cells possess a...

Modelling of a Filter Drying Process

Oct 29, 2012

Mark A. Pinto

Filter drying, also referred to as vacuum contact drying, is a process widely used in the pharmaceutical industry to remove water or organic solvents. The advantage of this process over other drying operations is that it can be used to dry solids that are sensitive to oxygen and temperature. The...
