由稻壳制备高比表面积活性炭

Preparation of Active Carbon with High Specific Surface Area From Rice Husks

以稻壳为原料 ,KOH为活化剂制备了高比表面积活性炭 ,其比表面积超过 30 0 0 m2 /g,且孔径均一 。

The active carbon with a high specific surface area(more than 3 000 m 2/g) was prepared by activating the carbonized rice husks by using potassium hydroxide as the activating agent.The effects of preparation parameters on the properties of the active carbon were studied, and its structure was characterized preliminarily.
