英文摘要In order to identify the effects of different chemical pretreatment methods on structure changes of corncobs and their subsequent pyrolysis characteristics, the chemical pretreatment of corncobs was performed using different concentrations of sodium hydroxide (NaOH), sulfuric acid (H2SO4), and hydrogen peroxide (H2O2) solutions. The structure changes of corncobs were characterized by elemental analysis, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD). The pyrolysis characteristics of raw and pretreated corncobs were conducted on thermogravimetric analyzer (TGA) and pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS). TG/DTG analysis of raw and pretreated corncobs demonstrated that the rank order for the ease of pyrolysis was untreated < 1% NaOH < 1% H2O2 < 2% NaOH < 2% H2SO4 < 1% H2SO4. Py-GC/MS analysis showed that chemical pretreatment can effectively promote the production of furans and levoglucosan (LG) and inhibit the formation of acetic acid, ketones and phenols. The rank order of LG yields from untreated and pretreated corncobs was untreated < 1% NaOH < 2% NaOH < 1% H2O2 < 1% H2SO4 < 2% H2SO4. The maximum yield of LG (15.01%) was obtained by fast pyrolysis of corncobs pretreated using 2% H2SO4. It was 18.53 times the yield of LG from untreated corncobs. The results could be mainly attributed to the passivation of alkali metal and alkali earth metal and the removal of hemicellulose and lignin fractions during pretreatment. (C) 2017 Energy Institute.
