Abstract
Bamboo was carbonized at different temperatures ranging from 200°C to 600°C. The dependence of the change of hemicellulose, cellulose, and lignin on the temperature was investigated by means of elemental analysis and Fourier Transform Infrared (FTIR) spectra of the residual solid products. The results showed (1) Below 200°C, hemicellulose in bamboo was decomposed and a large amount of hydroxyl groups are dislocated from hemicellulose and cellulose, accompanied by the evolution of water to escape (2) 200°C–250°C, cellulose in bamboo was drastically decomposed whereas the net structure of lignin keep stable, with the except of the dislocation of methoxyl groups from lignin. (3) 250°C–400°C, the net structure of lignin collapse, up to 400°C, followed by that the more position in aryl groups are substituted. (4) For bamboo carbonization, the aromatization of residual carbon has approximately completed at the temperature as high as 600°C. But the fusion of aromatic rings possibly does not occur.
