Improving the Sustainability of Biofuels Through Modification of the Biomass Production Subsystem: Application to Corn and Lignocellulosic Ethanol

Oct 17, 2011

Robert A. Urban

Concerns about dwindling fossil fuel reserves and climate change, energy independence, and depletion of ecosystem goods and services have driven the development of alternative technologies such as biomass-based fuels (biofuels). Although biofuels may be a step towards alleviating the aforementioned...

Pennycress-Derived Jet Fuel and Diesel LCA: Sustainable Advanced Biofuels

Oct 17, 2011

Jiqing Fan

Pennycress-derived jet fuel and diesel show promise as emerging biofuels that can help reduce dependence on petroleum imports, lower the trade deficit, and most importantly, lower greenhouse gas (GHG) emissions. Pennycress is a prolific seed producer with yields of more than 2000 pounds of per acre...

The Destruction of Dioxins In Fly Ash by Using Gliding Arc In Tornado

Mar 14, 2011

Liang Yu

The characteristic of gliding arc in tornado was investigated under different experimental conditions and the destruction of PCDD/Fs (polychlorinated dibenzo-p-dioxins/polychlorinated dibenzofurans) in medical waste incinerator fly ash by using a dc gliding arc in tornado reactor was studied in the...

Sustainability Evaluation of LNG Processing Technologies

Oct 17, 2011

Preeti Gangadharan

Growing demand for clean fuels has led to a renewed urgency in the search for alternative fuels. With the recent shale gas development initiatives, natural gas is poised to capture a much larger share of the energy market. Being clean-burning, natural gas provides many environmental advantages over...

Accounting for Ecosystem Services in Ecologically Based Life Cycle Assessment (Eco-LCA) by Combining Qualitative and Quantitative Information

Nov 12, 2009

Shweta Singh

The need of accounting for ecosystem services has been unanimously accepted to be crucial for meeting the goal of sustainability as purported by MEA report [1] .The Ecologically Based Life Cycle Assessment (Eco-LCA) has been recently developed to meet the requirement of accounting for the role of...

Stabilization of Hanford K-Basin Sludge by Dissolution of Uranium Metal with Carbonate / Peroxide Solution

Oct 18, 2011

Stuart T. Arm

The Hanford K Basins were used until the mid 1960s to store, under water, spent nuclear fuel from the site’s reactors before reprocessing to recover uranium and plutonium. A sludge consisting of cladding corrosion products, uranium, fission products and other debris accumulated on the floor of the...

The Energy Challenge: Providing Sustainable Supplies to Meet Growing Demand

Mar 13, 2011

F. Emil Jacobs

As economies grow and living standards improve, the world faces a dual energy challenge: meeting the growing demand for energy while mitigating emissions and their impact on the environment. ExxonMobil believes that addressing this dual challenge requires an integrated set of solutions which...

A Compact Integrated Warm Syngas Overall Cleanup System

Nov 8, 2010

Liyu Li

Gasification of coal or biomass to syngas followed by catalytic synthesis of ammonia, hydrocarbons or oxygenates provides a feasible strategy to meet the increasing demand for fertilizers and transportation fuels. This syngas has many impurities, including As, Be, Cd, Cl, Cr, Hg, K, N, Na, P, Pb, S...

Theoretical Screening Good Sorbents for CO2 Separation

Mar 23, 2010

Yuhua Duan

Carbon dioxide is the major product from coal combustion and is released into the air and causes global climate warming which we are facing today. Current technologies for capturing CO2 including solvent-based (amines) and CaO-based materials are still too energy intensive. Hence, there is critical...

Recent Advances in the High Temperature Capture of Elemental Mercury by Inorganic Sorbents: Packed Bed and Flow Reactor Studies

Mar 21, 2010

Jost O.L. Wendt

This paper reports on recent results relating to high temperature sorption of metallic mercury on MinPlus sorbent, an inorganic substrate derived from paper recycling residues. Results from a packed bed reactor as well as in-flow dispersed phase reactor are reported. A new type of packed bed was...

Beyond Water: Expanding the Spectrum of Efficient Large Scale Separations

Oct 18, 2011

William J. Koros

Innovations in membrane materials, structures, modules and system design have fundamentally changed the water purification industry over the past four decades. Revolutionary reductions by a full order of magnitude in energy consumption per unit of delivered product were achieved by substituting...

Transitioning to Low Carbon Power Generation by Integrating Renewables with Fossil Energy

Nov 7, 2010

Michael Matuszewski

It is expected that environmental regulations will be enacted to restrict the amount of carbon emissions from today's power plants. As such, it is likely that carbon capture and sequestration (CCS) technologies will be added to both new and existing coal-fired power plants to achieve compliance...

Lifecycle Assessment and Policy: Implications of the Renewable Fuel Standard for Upper-Midwest Energy Supply

Oct 17, 2011

Michael J. Brodeur-Campbell

Lifecycle Assessment and Policy: Implications of the Renewable Fuel Standard for Upper-Midwest Energy Supply Michael Brodeur-Campbell 1 , Jordan Klinger 1 , Kathleen Halvorsen 2,3 , and David Shonnard 1,4 [1] Department of Chemical Engineering, Michigan Technological University [2] Department of...

On-Line Studies of Pd Based Sorbents for the Removal of Gaseous Metal Contaminants: Capture and Regeneration

Mar 21, 2010

Erik C. Rupp

The Integrated Gasification Combined Cycle (IGCC) is a promising technology for the future use of coal to provide clean energy in a more efficient manner. During this process, many of the trace elements present in coal are volatilized, and remain in the gas phase through the gas turbine, only to be...

Creating Chemistry for a Sustainable Supply Chain

Nov 7, 2010

Charlene A. Wall-Warren

BASF, the world's leading chemical company, has a strong history of programs to foster sustainable development, including our eco-efficiency life cycle analysis program which we developed in partnership with outside experts in 1996. To date we have conducted over 400 eco-efficiency analyses for...

Water Sustainability Plenary

Apr 29, 2009

Mary Ellen Ternes

This special plenary session will feature invited speakers to provide a summary of water law and policy that will provide attendees with a better understanding of water law, which is based upon water as a resource, rather than as a commodity as it is sometimes perceived, as well as water resource...
