Abstract

Abstract

Pyrolysis characteristic of enzymatic/mild acidolysis lignin (EMAL) from moso bamboo was investigated using fast pyrolysis technology coupled with gas chromatography/mass spectrometry (Py-GC/MS). Pyrolysis mechanism and formation and distribution of pyrolysis products were studied. Pyrolysis temperature, as a vital factor, affects on lignin pyrolysis including its products and reaction pathway. The results show that pyrolysis products derived from EMAL pyrolysis are mainly heterocyclic (2, 3-dihydrobenzofuran), phenols, esters, and a few amount of acetic acid. Pyrolysis temperature has a distinct impact on the amount of pyrolysis products. At low temperature range (250~400 ℃), pyrolysis products are almost 2, 3-dihydrobenzofuran and its highest content is 66.26% at 320 ℃. At high temperature range (400~800 ℃), a most of pyrolysis products are phenols reaching the highest level of 62.58% at 600 ℃, and a few amount of acetic acid only occurs at 800 ℃.
