利用物理吸附分析仪和扫描电子显微镜分别对原料煤成型、炭化和活化过程中的物料形貌和孔结构进行表征研究。结果表明，活性炭制备过程中的炭化和活化工艺是煤基活性炭最为关键的工艺过程之一，对煤基活性炭成孔效果有重要的影响。如果只对物料进行炭化处理而不进行活化工艺，则物料不会形成活性炭所具有的发达的孔隙结构；反之，如果不经过炭化过程而直接进入活化阶段，其结果是尽管可以使活化料产生一定的孔隙结构，然而由于其比表面积和孔容增长有限，达不到预期的吸附效果。物料依次进行适当的炭化和活化过程，产物的孔结构才能得到充分发展，从而才能制备出满足一定需要的活性炭产品。

With automated physisorption and chemisorption analyzer and scanning electron microscope,the material and pore structure was researched during raw coal ’s process of forming, carbonizing,and activating.The research shows that during the preparation process of activated carbon,the vital craft processes of coal-based activated carbon were carbonization and activation,which tremendously affected coal-based activated carbon pore forming effect.The material can not form the well-developed pore structure that activated carbon has unless it is both carbonized and activated.If the material is activated without being carbonized,it can not reach anticipated adsorbing effect because of the limited growth of specific surface area and pore volume,although it can make the activated material create a certain of pore structure.The pore structure of the outcome can be fully developed only when the material is in turn in proper carbonization and activation process,and accordingly the activated carbon products which and meet some kind of demand can be made.
