英文摘要	two-staged biomass pyrolysis process consisting of torrefaction and subsequent fast pyrolysis is proposed to obtain high quality bio-oil. the purpose of this study is to evaluate the effect of torrefaction temperature on yield, composition, and physical properties of the liquid of torrefaction and bio-oil. torrefaction of pine was conducted on an auger reactor at 240-320 degrees c with a residence time of 40 min to produce liquid of torrefaction and torrefied pine. then, the torrefied pine was fast pyrolyzed in a bubbling fluidized bed reactor at 520 degrees c to produce bio-oil. torrefied pine was characterized by chemical composition analysis and fourier transform infrared (ftir) spectroscopy. the liquid of torrefaction was determined by gas chromatography (gc); bio-oil was characterized by gas chromatography mass spectroscopy (gc-ms) and c-13 nuclear magnetic resonance spectrometry (nmr). the experimental results show that water content in liquid of torrefaction and water and acetic acid content in bio-oil decreased with elevated torrefaction temperature, while the yield of liquid of torrefaction, aromaticity, higher heating value, and density of bio-oil increased. however, the yield of total liquid (sum of liquid of torrefaction and bio-oil) decreased significantly with elevated torrefaction temperature because of the cross-linking and carbonization of torrefied pine.
