Heat and mass transfer during pyrolysis of major components bed have been investigated numerically. For Cellulose powder, the calculation temperature and velocity vector distributions had a quasi-steady state during pyrolysis because the gas volume increased near the side wall of the packed bed and then the effective thermal conductivity decreased. The calculation temperature with the effect of volume shrinking of the packed bed agreed qualitatively with the experimental ones for all kinds of powder when the temperature plateau appeared.
