Four kinds of biomass (Chinese silvergrass, corn stalk, rice husk and pine) in China were selected as experimental samples for this study. Pyrolysis process of these biomass was researched by thermogravimetric Fourier transform infrared spectroscopy at 10 K/min. The results show that the pyrolysis process of all samples can be divided into three stages, and the comprehensive characteristics of volatile release degree of Chinese silvergrass is the highest, followed by corn stalk and rice husk, the lowest is pine. FTIR spectra results indicate that the pyrolysis gaseous products are mainly CO2, CO, CH4 and H2O. Kinetic parameters of the biomass were analyzed and determined by Coats-Redfern method, and the results show that corn stalk is the most susceptible to pyrolysis because the activation energy of Chinese silvergrass, corn stalk, rice husk and pine are 46.7, 29.3, 54.3 and 58.1 kJ/mol respectively.
