摘要：

Based on the investigation of the polysaccharide structure of cellulose by using Fourier transform spectrum analysis,the pyrolysis behavior of cellulose was studied at a heating rate of 20 K/min by thermogravimetric(TG) analysis coupled with Fourier transform infrared spectroscopy(FTIR).Experimental results showed that the decomposition of cellulose mainly occured at the temperature range of 550~670 K.The weight loss became quite slow when temperature increased further up to and above 680 K and the(amount) of residue finally reached to a mass percent of 14.7%.FTIR analysis showed that free water released out first during cellulose pyrolysis,followed by the depolymerization and dehydration.Glucosidic bond and carbon-carbon bond broke into a series of hydrocarbons,alcohols,aldehydes,acids,etc.Subsequently these large-molecule compounds decomposed further into gases,such as methane and carbon monoxide.
