Heat and mass transfer during co-pyrolysis of packed bed of pulverized coal and polystyrene have been investigated. Mass fraction of the pulverized coal in the mixed powder and polystyrene was changed from 0.00 to 1.00. The temperature in the packed bed of pulverized coal increased monotonously with time and approached to the steady state value of it except for until 375 K due to the evaporation of water. On the other hand, temperature in the packed bed of polystyrene bed increased initially with time and then didn't change due to endothermic pyrolysis of it at 450K. After that the temperature increased again and approached to the steady state value. The co-pyrolysis rate could controlled by the decomposition of pulverized coal when the mass fraction of the coal was greater than 0.25.
