A series of experiments were conducted to compare the pore development in palm-shell and coconut-shell-based activated carbons produced under identical experimental conditions. Carbonization and activation processes were carried out at 850 degrees C using a fluidized bed reactor. Within the range of burn-off studied, at any burn-off, the micropore and mesopore volumes created in palm-shell-based activated carbon were always higher than those of coconut-shell-based activated carbon. On macropore volume, for palm-shell-based activated carbon, the volume increased with increase in burn-off up to 30% and then decreased. However, for coconut-shell-based activated carbon, the change in macropore volume with burn-off was almost negligible but the absolute macropore volume decreased with burn-off.
进行了一系列实验，以比较在相同实验条件下生产的基于棕榈壳和椰壳的活性炭中的孔隙发展情况。碳化和活化过程在850摄氏度下使用流化床反应器进行。在所研究的烧失范围内，在任何烧失率下，基于棕榈壳的活性炭中产生的微孔和中孔体积总是高于基于椰壳的活性炭。关于大孔体积，对于基于棕榈壳的活性炭，体积随着烧失率增加至30%而增加，然后下降。然而，对于基于椰壳的活性炭，大孔体积随烧失率的变化几乎可以忽略不计，但绝对大孔体积随烧失率而下降。
