Leadership Is Everyone’s Responsibility

Feb 20, 2013
Greg Shaffer

This webinar discusses the “hidden leadership” opportunities that are woven into everyday roles, how to recognize these opportunities and take advantage of them.

Emissions of Mercury and Other Air Toxics: Compliance Strategies for Coal Combustion

AIChE and A&WMA Web Forum
Jan 23, 2013
Bob Fraser, Constance Senior, Nick Hutson

What do you need to know about mercury, HCI, metals and other toxics control? This webinar will address technical and permitting issues from two perspectives: what is required (by Nick Hutson of USEPA) and what strategies could you adopt (by Bob Fraser of ERM).

High Efficiency Direct Electrochemical Conversion of CO2 to Liquid Fuel

Oct 30, 2012
Jingjie Wu
In this paper, we will discuss a design of an electrochemical cell for CO 2 reduction implementing a proton exchange membrane (PEM) by adding a liquid buffer layer between the membrane and the cathode electrode. This configuration enables production of liquid fuels from CO 2 on Sn gas diffusion...

Harnessing Applied Potential for Sunlight Driven CO2 Utilization

Oct 30, 2012
Benjamin R. Buckley
Escalating CO 2 emissions due to increasing fossil fuel consumption is generally acknowledged as one of the major contributors to global warming. Therefore, the development of methods for reducing the amount of CO 2 released is a major challenge with significant societal consequences. Pressures on...

Kinetics of Hydrolysis of Sodium Borohydride with Water Vapor

Oct 30, 2012
Lin Yu
Hydrolysis of sodium borohydride is one route for solid state hydrogen storage and release. Compared with the aqueous phase reaction, the hydrolysis of sodium borohydride with water vapor gives a faster reaction for hydrogen production. Prior studies on the water vapor hydrolysis from our group...

Multi-Physics Modeling of Auto-Thermal Diesel Surrogate Reforming

Oct 30, 2012
Rajesh D. Parmar
Abundant supply and existing infrastructure makes diesel a favorable candidate for portable energy supply. Diesel generators are widely used in locations where there is no reliable electric grid, but they are noisy, have emission issues, and often have poor fuel efficiency in practical operations...

Adsorption Based Hydrogen Storage System; Multiscale Approach and Mathematical Model

Assessing the Potential for Large-Scale Utilization of Fossil-Fuel Derived CO2

Oct 30, 2012
John J. Marano
Barring the imposition of a carbon tax (or equivalent cap-and-trade program) and corresponding international agreements, it is highly unlikely that carbon capture and storage/sequestration (CCS) will be implemented in any meaningful way in the near future. This is due to inherent inefficiency and...

Fuel Processing: Renaissance of the Second Decade (Keynote)

Oct 30, 2012
Brant. A. Peppley
The early development of fuel processing technologies for fuel cell systems was, to a great extent, driven by fuel cell automobile programs. At the time an on-board reformer was believed to be the best option for fuel cell automobile commercialisation. Regrettably, the belief that we simply needed...

Engineering Pellets of Biomass Blends

Oct 30, 2012
M. Toufiq Reza
Transportation and handling of lignocellulosic biomass are often challenging and expensive due to low bulk density, in the range of 60-80 kg/m 3 for agricultural straws and grasses and 200-600 kg/m 3 for woody biomass. Pelletization results in reduced transportation costs and provides for better...

Post-Combustion Gas Permeation Carbon Capture System Models

Oct 30, 2012
Juan E. Morinelly
Post-Combustion Gas Permeation Carbon Capture System Models Juan E. Morinelly, David C. Miller National Energy Technology Laboratory (NETL) Gas permeation membranes have been proposed as an alternative to amine absorption for post-combustion carbon capture [1,2]. Industrial-scale membrane systems...
