Preparation of Activated Carbon with Higher Absorbability from Anthracite

Abstract:

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 °C，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 %.
