Industrial Advisory Board Meeting Raleigh, North Carolina

1
Project Title

• Participating UniversitiesNames of Researchers

2
Objective To develop a more efficient
solvent-based pretreatment

• Potential Benefits
• Reduced cost
• Separate fractions of cellulose, hemicellulose,
  and lignin
• Efficient solvent recovery
• Less water use
• Higher downstream conversion efficiency

3
Approach

• Task 1 Compare three solvents
• Solvents x, y, and z
• Utilize corn stover as model feedstock
• Treatment conditions Temp, pressure, pH, time
• Analysis HPLC following enzymatic hydrolysis,
  mass balance

4
Approach

• Task 2 Compare treatment conditions
• Using best solvent
• Optimize various treatment conditions Temp,
  pressure, pH, time
• Analysis HPLC following enzymatic hydrolysis,
  mass balance

5
Approach

• Task 3 Determine effectiveness on alternative
  feedstocks
• Use optimal solvent and treatment conditions
  identified previously
• Compare corn stover to woody biomass and native
  grasses
• Analysis HPLC following enzymatic hydrolysis,
  mass balance

6
Approach

• Task 4 Economic and energy analysis
• Based on optimal conditions, conduct analysis for
  alternative feedstocks
• Perform sensitivity analysis on key variables.
