Comparison of Chemical and Biological Delignification of Cardboard

Oct 18, 2011
Estefania Isaza
Some processes aimed to biofuels production, use lignocellulosic wastes as feedstocks for fermentative conversion. If this is the case, pretreatment is required to make these resources fully digestible. Among a wide range of pretreatment options, this study focuses and compares oxidative-alkaline...

Hybrid Membrane Absorption Process for Post Combustion CO2 Capture

Mar 23, 2010
S. James Zhou
Gas Technology Institute (GTI) and PoroGen Corporation are jointly developing a novel hybrid membrane – absorption process for pre- and post-combustion CO2 capture (Carbo-Lock™ process). The novel Carbo-Lock™ process combines advantageous features of both absorption and membrane processes to...

Nationwide Energy Supply Chain Analysis for Transportation Fuels

Oct 16, 2011
Josephine A. Elia
Hybrid energy processes are an attractive avenue towards a more sustainable energy future due to their flexibility in converting multiple types of inputs into a consistent range of products. For the transportation sector, Fischer-Tropsch synfuels can be generated from a diverse of feedstock inputs...

Reducing Process Complexity for Cellulosic Ethanol

Oct 18, 2011
L.O. Ingram
Much of the process complexity and high capital costs associate with cellulosic ethanol (dilute acid hydrolysis as a pretreatment and enzymatic saccharification of cellulose) results from side products such as furfural, acetate, and soluble lignin compounds that inhibit the biocatalysts. Inhibitor...

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...

Thermochemical Hydrogen Production by Alkali Metal Oxides

Oct 16, 2011
Hiroki Miyaoka
In this work, we have focused a thermo chemical hydrogen production from water by using alkali metal oxides. This system consists of three step reactions. First one is H 2 generation by the reaction of hydroxide and metal 2MOH+2M→2M 2 O+H 2 (endothermic). From the oxide as the product of first...

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...

Real Time Detection of Gaseous Metal Contaminants in Coal Flue and Fuel Gas

Mar 21, 2010
Erik C. Rupp
The Integrated Gasification Combined Cycle (IGCC) is a promising technology for the future use of coal to provide energy. 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 released in the flue gas. Trace...
