AbstractEucalyptus wood powder was first subjected to hydrothermal pretreatment in a high-pressure reactor at 160-190 degrees C, and subsequently fast pyrolyzed in a fluidized bed reactor at 500 degrees C to obtain high quality bio-oil. This study focused on investigating effect of hydrothermal pretreatment on bio-oil properties. Hemicellulose and some metals were effectively removed from eucalyptus wood, while cellulose content was enhanced. No significant charring and carbonization of constituents was observed during hydrothermal pretreatment. Thus pretreated eucalyptus wood gave higher bio-oil yield than original eucalyptus wood. Chemical composition of bio-oil was examined by GC/MS and C-13 NMR analyses. Bio-oil produced from pretreated eucalyptus wood exhibited lower contents of ketones and acids, while much higher levoglucosan content than bio-oil produced from original eucalyptus wood, which would help to improve thermal stability of bio-oil and extract levoglucosan from bio-oil. Hydrothermal pretreatment also improved bin-oil fuel quality through lowering water content and enhancing heating value. (C) 2013 Elsevier Ltd. All rights reserved.
