摘　　要：以石油焦为原料 ,用不同的催化剂和活化方法制备不同性能的粉状活性炭。试验结果表明 ,采用碱活化法 ,可对石油焦的紧密结构进行有效的侵蚀破坏 ,在一定的活化条件下 ,可制取比表面积 3 0 0 0m2 /g的超级活性炭。改变催化剂的用量及两种催化剂的比例可以有效地改变活性炭的微孔结构及孔半径。Powder active carbons with different performance were prepared from petroleum coke by different catalyst and activation methods.The results show that tight structure of the petroleum coke is effectively destroyed by use of the alkali activation method and a super active carbon with specific surface area of 3000 m 2/g is obtained under definite conditions.The structure and pore size of the active carbon are effectively changed by alteration of dosage and ratio of the catalyst.
