N2 - Molding biomass's carbonization homogeneity was studied through doing research on temperature difference of surface and inside of biomass by making experiments. Molding biomass's size is larger than that of small dimension biomass and carbonization in whole biomass is different to some extent. But endothermic and exothermic effect in pyrolysis process and mass transfer of volatile are beneficial to carbonization homogeneity. When biomass average heating rate becomes larger, the maximum temperature difference of surface and inside becomes larger, besides that the temperature of biomass is higher when molding biomass's carbonization is homogeneous. Maximum temperature differences were 30, 76, 137 °C respectively when biomass average heating rates were 5, 10, 20 °C/min. In order to ensure homogeneity, carbonization should reach the temperature which lignin decomposes strongly at releasing heat violently. Carbonization temperature should be higher than 450 °C. Besides, biomass average heating rate shouldn't be too high and it should be under 20 °C /min.
