Preparation of Activated Carbon with Higher Absorbability from Anthracite

摘要：

　　This paper studied experimental conditions of making higher absorption activated carbon from Jincheng anthracite.The result was obtained by using the orthogonal experiment in which four factors were designated:the carbonization temperature,the carbonization time,the activation time as well as the additive types,with the target of iodine value.The optimized parameters had been found out:the carbonization temperature is 600 ℃,the carbonization time is 1.5 h,the activation time is 4 h and the additive is NaNO3 which is better in a weight proportion of 8 %.At last,under the optimized parameters,the better activated carbon products could be gained by acid pickling,which has a higher iodine value 1094.8 mg/g and low ash content 8.73 %.
