Activated carbon for dioxins removal from flue gas of municipal solid waste (MSW) incineration plants contains high concentration dioxins. We investigated the dechlorination treatment of dioxins in the activated carbon using superheated steam which can be gotten easily in MSW incineration plants. Laboratory scale experiments on the treatment of dioxins in activated carbon using superheated steam were performed. The following points have become clear from the experiments. Superheated steam can dechlorinated dioxins at over 350℃. Treatment efficiency depended on treatment time and temperature. The efficiency of TEQ value treatment were 22% for 15 min. and 55% for 40 min. at 350℃.
