The effect of carbonization temperature,the ratio of KOH to carbon,activation temperature and activation time on adsorption propertied of activated carbon were systematically studied by orthogonal expriments,and the optimum condition of the preparation of activated carbon with superhigh specific surface area was confirmed.

The super-high specific surface area activated carbons(S_(BET)>2500m~2·g~(-1)) were prepared from petroleum coke using KOH as activation agent under different activation conditions.

The macrokinetics of vinyl acetate synthesis from acetylene and acetic acid on the Zn(Ac)_2/super-high specific surface area activated carbon (s_(BET)=2713m~(2)/g) catalyst has been studied under conditions approaching those of industrial operation, and compared with Zn(Ac)_2/Japaniese coco-shell carbon (s_(BET)=1384m~2/g) catalyst.

6 F/g when the super-high specific surface area activated carbon has a specific surface area of 2 827 m2/g.
