ABSTRACT

Fly ash consists of various metal oxides which can remove SO2 gas by the catalyst efect. When fy ash is added in the prepa�ration process of pitch-based activated carbon, the pitch particles aggregate and fy ash is embedded in the activated carbon. To increase SO2 gas removal performance, activated carbon was prepared by surface-treated fy ash and petroleum-based pitch. Carboxyl groups were introduced into the fy ash by malic acid treatment. The introduced carboxyl groups acted as an activation agent to create micropore around the fy ash, and created micropores were exposed to the fy ash outside of the activated carbon. The exposed fy ash increased removal amount of SO2 gas by a catalytic efect of the metal oxides. The SO2 gas removal performance improved by 34% because of the catalyst efect of the exposed fy ash and improvement in the micropore structure in the activated carbon.
