摘　　要：A new technique to deash activated carbons from coal, which uses a chemical additive together with acidwashing, is developed. By using the technique, it can decrease the ash of activated carbons to 1. 0%~3. 5%, improve the absorbability, increase the activation rate, and reduce the production cost.
