摘要：
The thermogravimetric of sugarcane bagasse pretreated by hot-water has been studied in this paper. Results indicated that residual solid pretreatment by hot water could decrease the activation energy of phase 2 (270-350 degrees C) obviously, which makes the pyrolysis more energy-saving. By hot water pretreatment, the hemicellulose, especially xylose (9.78%/o.d. dry mass at 170 degrees C and 1 h) was greatly extracted into hydrolyzates liquor. Greatly minimized hemicellulose waste at low temperature during pyrolysis also agreed with biorefinery concept. Therefore, bagasse with hot-water pretreatment should be a good pyrolysis material for value-added material. Crown Copyright (C) 2012 Published by Elsevier Ltd. All rights reserved.
