Temperature and heat of reactions have been measured during fast pyrolysis of biomass powder packed bed. For cellulose powder, temperature at the center of the bed, T_C, increased monotonously with time due to thermal conduction for T_C < 500K. The temperature increased slowly with time due to endothermic decomposition of cellulose for 500 K < T_C < 600 K. On other hand, exothermic behaviors for xylan powder and lignin one were significantly observed at TC > 500 K and at T_C > 600 K, respectively. Furthermore, numerical simulation of fast pyrolysis of cellulose powder packed has been conducted.
