Abstract: The wood-based activated carbon microspheres were prepared from Chinese fir.The thermal stability,chemical structure of precursors and the pore structure parameters of activated carbon microspheres were investigated.The results showed that as the curing temperature raised,the peak temperature of maximum reaction rate was gradually shifted to higher temperature.FT-IR analysis showed that the crosslinking structure from dehydration condensation reactions enhanced the thermal stability of precursors.The BET analysis showed that the activated carbon microspheres had a typical microporous structure and irregular mesoporous structure,and the specific surface area was first increased and then decreased as the curing temperature increased.When the curing temperature was 75℃,the maximum specific surface area value was 1502m2/g,the micropore and mesopore pore volumes were 0.488cm3/g and 0.261cm3/g,respectively.
