Abstract

Abstract: In lignocellulosic ethanol production process, utilization of separated lignins can improve the economy of cellulosic ethanol technology. In this article using poplar power as feedstock, lignin extracted from three methods were analyzed and compared from the perspective of lignin yield and molecule modification degree. Phosphoric acid-acetone lignin is characterized by its high yield of 15%~25%. Alkaline cooking and organic solvent method can only reach 9.58% and 13.47%. By FT-IR characterization, it is confirmed that phosphoric acid-acetone lignin has the biggest absorption signal at 1608 cm-1, 1507 cm-1 and 1463 cm-1, and its conjugated carbonyl absorption peak also exists at 1650 cm-1. This result indicate that it has the lowest modification. 1H NMR analysis also supports this conclusion. Phosphoric acid-acetone pretreatment can raise the economy of cellulosic ethanol process under lower temperature and normal pressure.

Key words: cellulosic ethanol, lignin, phosphoric acid-acetone pretreatment, FT-IR, 1H NMR
