摘要
本文以石油焦为原料，采用氢氧化钾化学活化法系统考察了氢氧化钾／焦炭的质量配比（碱／炭，Ｗｂ／Ｗｃ）对活性炭吸附性能和孔隙性能的影响。结果表明，随着碱／炭比的增加，吸附性能显著提高；比表面积，总孔容积，微孔容积和非微孔容积都增加；孔径分布变窄，平均孔径减少。碱／炭比大于等于３∶１时，所得活性炭试样的比表面积大于３０００ｍ２／ｇ。
The effects of the weight ratio between potassium hydroxide and petroleum coke (Wb/Wc) on the adsorption properties and pore properties of activated carbon were studied by a direct chemical activation routein which petroleum coke was reacted with excess potassium hydroxide.Results show that with the increase of Wb/Wc,adsorption properties rise remarkably;specific surface areas,volumes of total pore,micropores and non micropores increase;pore size distribution becomes narrow and average pore diameter decreases.When Wb/Wc is greater than or equal to 3 to 1,specific surface areas of activated carbor are greadter than 3000m 2/g.
