Abstract
The development of flue gas desulphurization technologies and the control and reduction of SO2 pollution from coal combustion have become a hot research topic due to environmental concerns. Carbonaceous and carbon supported desulfurizing sorbents have highly porous structures, large specific surface area and low production costs and can be widely used as desulfurizer. This paper provides a comprehensive review of carbonaceous and carbon-based desulfurizing sorbents, including active components, compositions of raw gas and effects of process operation conditions. It can be concluded that the use of char supported metal desulfurizing sorbents for removing sulfur dioxide from flue gas is a promising technology. Different aspects of applications of carbonaceous and carbon-supported desulfurization sorbents are discussed in detail.
