| Abstract: | In this paper, activated carbons were made from fly ash with steam activation. The influences on activated carbon of activating temperature, activating time and activating reagent were developed. Results showed that there were many more relations between activating temperature & time and BET specific surface area and the properties of activated carbon. |
