Speaker: Dr. Badal C. Saha, “Fuels and Chemicals from Biomass: Challenges and Opportunities”
|
Talk Abstract:
In the U.S., the production of corn grain based ethanol reached 4.5 billion gallons in 2005, a fraction of the 140 billion gallons of transportation fuel used annually. The goal is to displace 30% of the nation_s current gasoline use with ethanol by 2030 and this will require production levels equal to roughly 60 billion gallons a year. If all corn grain now grown in the US is converted to ethanol, it can satisfy approximately 15% of current transportation fuel needs. Thus, developing ethanol as fuel, beyond its current role as fuel oxygenate, will require developing lignocellulosic biomass as feedstock because of its abundance. This includes various agricultural residues such as corn fiber, corn stover, rice straw, wheat straw and sugarcane bagasse, and energy crops such as switchgrass. In this presentation, the current state of research and development for cost-effective conversion of lignocellulosic feedstock to fuel ethanol, and efforts to bring the technology into the market place will be reviewed. Recent research progress dealing with the production of some other value-added chemicals from biomass will also be described.
