Fig. 1From: Comparison of ethanol production from corn cobs and switchgrass following a pyrolysis-based biorefinery approachProcess schematic for the production of sugars via fast pyrolysis followed by upgrading and yeast fermentation. The feed streams are abbreviated as AACC and AASG for acidic acid-pretreated corn cobs and switchgrass, and NACC/NASG for nitric acid-pretreated corn cobs and switchgrass. The detoxification routes are abbreviated as a) W-H: cold water extraction followed by hydrolysis; b) W-H-EAc: cold water extraction followed by hydrolysis and ethyl acetate extraction; and c) W-EAc-H, cold water extraction followed by ethyl acetate extraction and hydrolysisBack to article page
