In this report, the yield of solid component undergoing the fast and slow pyrolysis in the packed bed of biomass particles has been compared with the analyzed one by the different three kinetic models (model-1: Thurner et.al, model-2: Mohan et.al, model-3: Miller et.al). From the results, the yield of solid component could be reproduced by the analysis using the model-3 even if the heating rate and the lignin content changed. Furthermore, the relationship between the volume reduction process in the packed bed and the chemical reaction undergoing pyrolysis was elucidated by the formularization. From the result, the volume in the packed bed of the biomass undergoing the pyrolysis can be estimated by using the model-3 and the dependence of gas volume in the bed on the temperature.
