Abstract
The pyrolysis behaviors of cotton stalk, corn stalk and corn cob have been investigated with the thermogaravimetric ananlysis(TGA) coupled with Fourier transform infrared spectrometer(FTIR). The results from TGA show that there are two reaction stages in the pyrolysis process, corn cob is easier to decomposition than others at the same temperature, and their pyrolysis process is different from each other. Different chemical component ratio maybe link with the variable biomass pyrolysis behaviors. The corn cob yield the most organic compound for its highest content of cellulose and the cotton stalk yield the most non-condensable gas in addition to H2 for its highest content of hemicellulose from the integrated data of peak area. Thus, the content of cellulose and hemicellulose have an important role in the biomass pyrolisis.
