摘　　要：以内蒙蒙东褐煤为原料,在活性焦制备小试实验装置上,以水蒸气为活化介质,用正交实验方法考察了活化温度、活化时间和水蒸气流量对活性焦产品的碘吸附值、亚甲基蓝吸附值及收率的影响.结果表明,综合考虑活性焦的亚甲基蓝吸附值及收率的影响,最佳的活化条件为:活化温度800℃,活化时间为90min,水蒸气流量2g/min,在最佳工艺条件下所制得的活性焦中孔发达,中孔孔径在4.0nm附近分布比较集中.This paper presented the preparation of activated coke from Inner Mongolia East Mongolia lignite.The activation reactions were studied using the tubular electro-thermal furnace with water stream as activation gas.The orthogonal experiments,in which the activation conditions were activation temperature,activation time and vapor velocity,were carried out to inspect the effects of reaction conditions on activated coke properties.The result shows that the optimum activation conditions were determined as：activation temperature 800 ℃,activation time 90 min and vapor velocity 2 g/min,with comprehensively consideration of methylene blue adsorption value and yield rate.The sample which was prepared under the optimum condition had a developed mesopore with a diameter of 4 nm.
