| 英文摘要 | pretreatment of corncobs using torrefaction was conducted in an auger reactor at 250-300 degrees c and residence times of 10-60 min. the torrefied corncobs were fast pyrolyzed in a bubbling fluidized bed reactor at 470 degrees c to obtain high-quality bio-oil. the heating value and ph of the bio-oil improved when the torrefaction as pretreatment was applied; however, increasing bio-oil yield penalties were observed with increasing torrefaction severity. fourier transform infrared spectroscopy (ftir) and quantitative solid c-13 nuclear magnetic resonance spectrometry (nmr) analysis of torrefied corncobs showed that the devolatilization, crosslinking and charring of corncobs during torrefaction could be responsible for the bio-oil yield penalties. gas chromatography-mass spectrometry (gc-ms) analysis showed that the acetic acid and furfural contents of the bio-oil decreased with torrefaction temperature or residence time. the results showed that torrefaction is an effective method of pretreatment for improving bio-oil quality if the crosslinking and charring of biomass can be restricted.
