- A database of biomass-syngas constituents based on several feedstocks including switchgrass, wheat straw, and corn gluten as well as co-firing of switchgrass and wheat straw with coal.
- An assessment of biomass-syngas constituents on the effects of cell growth, substrate consumption, ethanol production, and enzyme activity.
- An assessment of the effects of gasification agents on generated biomass-syngas species and the fermentation process.
- The development of a scrubbing system to reduce nitric oxide levels.
- The development of gas clean-up systems to reduce or eliminate other biomass-syngas contaminants that are found to affect the fermentation process adversely. The information obtained in the above mentioned deliverables would enable us to design a more efficient and economically viable gasification-fermentation process.
