Abstract

Abstract: To investigate the pyrolysis mechanism and the release law of pyrolysis products, the sulfate black liquor (BLS) from bamboo & eucalyptus was pyrolyzed and the process was investigated by thermogravimetric analyzer coupled with Fourier transform infrared spectrometry (TG-FT-IR). The results revealed that the release of BLS pyrolysis products, such as CO₂, CH₄, H₂O, CO and alcohols & phenols, aldehydes & ketones, were mainly concentrated in 500-2 000 s. The BLS pyrolysis process could be divided into three stages. The weight loss in the first stage should be attributed to the release of bound water in the raw material and the maximum weight loss rate was observed at 105℃. During the second weight loss stage from 173℃ to 518℃, the weight loss rate was about 25.19%, and the release products were CO₂, CH₄, H₂O, alcohols & phenols, aldehydes & ketones and a small amount of CO, and CO₂ was the dominant product. The third weight loss stage was from 722℃ to 1 000℃, and the weight loss rate was nearly 39.05%. In this stage, CO was the dominant product and very few amounts of other small molecule products were observed.

Key words: sulfate, black liquor, pyrolysis, TG-FT-IR
