The recent development of de-SOx and de-NOx using activated carbon fibers (ACF) in Japan is introduced in this review comparing it with the conventional commercialized system. Pitch-based ACFs showed higher de-SOx activity than other ACFs from different precursors. De-SOx activity can be further modified by the heat-treatment, continuous and complete removal of SOx. ACF is also effective for removing NOx in the presence of NH4. The mechanisms of de-SOx and de-NOx on the surface of ACFs are proposed and discussed. Based on fundamental research results de-SOx, de-NOx and their combined processes are designed and proposed.
