Abstract: Nowadays, flue gas desulfurization and denitrification technology is widely used in the coal-fired power plants, and flue gas desulfurization and denitrification using biomass activated carbon has become a research hotspot due to its novelty, high efficiency, economy and resourcing. By using biomass activated carbon, the adsorption desulfurization is the dominant flue gas desulfurization technology, and the flue gas denitrification technologies are divided into low-temperature adsorption denitrification(including NO adsorption and NO oxidation adsorption), medium-temperature NH3-SCR denitrification and high-temperature heterogeneous reduction denitrification according to the flue gas temperature window. This work reviewed the effect of pore structure, surface chemical properties and surface modification on the performance of desulfurization and denitrification by using biomass activated carbon, and summarized the methods to improve the performance of desulfurization and denitrification. And finally, the future research would be aimed at building more general dynamic models for heterogeneous reduction denitrification reaction, improving the biomass activated carbon catalyst for NH3-SCR denitrification technology, preparing slow-release fertilizer from the desulfurization and denitrification using biomass activated carbon and simultaneously removing the multi-pollutant by using the modified and metal-loading biomass activated carbon.
