摘要
Abstract
In this paper,a series of activated carbons with high specific surface area were prepared by using KOH as an activation agent and delayed petroleum coke as raw material.The effect of KOH/Coke ratio,activation temperature and activation time on the yield and iodine adsorption value was investigated by orthogonal test and further single factor experiments.The results indicated that the significant factor for iodine adsorption value was KOH/coke ratio.The iodine adsorption capacity can be improved by increasing KOH/coke ratio,extending the activation time and selecting the appropriate activation temperature.A activated carbon sample with specific surface area of 2775 m2/g and total pore volume of 2.888 cm3/g was prepared under the conditions of KOH/coke ratio 4∶1,activation temperature 750 ℃ and activation duration 120 min,respectively.关键词
