Future Fuels and Chemicals: Grand Challenges and Opportunities

Apr 2, 2012
To insure a Sustainable Future, CO 2 emissions must be reduced despite strong future growth in demand. “Easy oil” from conventional production will be less abundant, though coal and natural gas, as well as unconventional hydrocarbon reserves will remain in strong supply for decades to come. Carbon...

Cellobiose Hydrolysis Using Acid-Functionalized Nanoparticles

Oct 18, 2011
Leidy Peña
Mineral acids have been used effectively for the pretreatment of cellulosic biomass to improve sugar recovery and promote its conversion to ethanol; however, substantial capital investment is required to enable separation of the acid, and corrosion-resistant materials are necessary. Disposal and...

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...

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...
