Pyrolysis characteristics of various biomass species were investigated with a thermogravimetric analyzer. Kinetic parameters that are activation energies and pre-exponential factors obtained by the Miura method changed dramatically during pyrolysis process. There was the case that kinetic parameters decrease with an increase in conversion for biomass pyrolysis, while activation energy for coal increases with increasing conversion. The decrease in kinetic parameters was caused by structural changes derived from softening, depolymerization, solidification and so on. Kinetic parameter distributions were available to the characterization of biomass pyrolysis.
