Abstract
Pyrolysis Char (PC) was activated with H_2O using a small rotary kiln type reactor to produce Activated Char (AC) for dioxin removal. Dioxin adsorptivity of AC was estimated by the amount of anthracene adsorbed on it at 168℃, Q_ANT. The Q_ANT value of AC produced from PC was 46% of Q_ANT value of a commercial activated carbon used for practical dioxin removal. The pore distributions of AC before and after anthracene adsorption showed clearly that AC keeping 1∿10nm pores are suitable for dioxin adsorption.
