以含油污泥为原料，氢氧化钠为活化剂，在氮气保护下，通过室内静态热解炉制备高比表面积活性炭。研究炭化温度、活化升温方式、活化温度、活化时间和碱碳质量比 m（NaOH）/ m（C）对高比表面活性炭的影响。采用全自动比表面与孔隙度分析仪、钨灯丝环境扫描电子显微镜等测试设备，分别对产品的比表面积与孔径分布、组成及微观形貌进行定性或定量分析。研究结果表明，含油污泥制备高比表面积活性炭的较佳条件为：炭化温度500℃，活化升温方式（c），活化温度800℃，活化时间1 h，m（NaOH）/ m（C）=2。采用本方法制备的活性炭比表面积大于2000 m2/ g，平均孔径小于2 nm，总孔容大于2 cm3/ g，性能优于普通活性炭，可作为能源储存介质、电极材料、高效吸附剂的基础材料，为含油污泥的资源化利用提供了一条新途径。

An activated carbon with high specific surface area was prepared from oily sludge. The whole preparation was put forth in a static pyrolyzing furnace with nitrogen and sodium hydroxide as the activation agent. The effects of conditions on the activated carbon were studied,such as carbonization temperature,heating way for activation,activa-tion temperature,activation time and the mass ratio(m(NaOH)/ m(C)). The specific surface area and pore size distri-bution were tested by the automated surface area and pore size analyzer. The element and microstructure were character-ized by ESEM. The results showed that the best experimental conditions were as the followings,the carbonization tem-perature was 500 ℃,the heating way for activation was method c,the activation temperature was 800 ℃,the activation time was 1 h,and m(NaOH)/ m(C)was 2: 1. The surface area of the activated carbon was more than 2 000 m2 / g. The activated carbon had uniform pore size and its average pore size was less than 2 nm. Its total pore volume was greater than 2 cm3 / g. Based on those features,activated carbon could be used as storage media for energy,electrode materials, highly effective adsorbents and others basic materials. Therefore,this research could give a new way for resource utili-zation of oily sludge.
