논문 초록 (Abstract)
Lignin is the major source of polyphenolic compounds available from natural biomass. Although most commercial lignin productshave been supplied from wood biomass, the residues from bioethanol production processes could be an additional potential source. About 75% of lig nin inherent in corn stover and rice straw was recoverable from the residues of bioethanol producing processes. Chemical structures and thermolysis features of the lignin residues from corn stover an d rice straw obtained through acid-alkali pretreatments were character ized. Due to inherent structural differences, the corn stover- and ri cestraw lignin were more reactive and had less thermal stability than t he wood-based Kraft lignin. The corn stover lignin showed the lowe st maximum degradation temperature with the highest mass loss rate in the primary pyrolysis reaction and it was mainly pyrolyzed into mon omers of lignin building blocks with a higher phenol content (10%), unli ke the other lignin samples (<6%).
