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.

The measurement of total mercury in flue gas based on an economical aluminum matrix sorbent was developed in this paper. A sorbent trap consisted of three tubes was employed to capture Hg from flue gas. Hg trapped on sorbent was transferred into solution by acid leaching and then detected by CVAAS. Hg adsorbed on sorbent was recovered completely by leaching process. The 87.7% recovery of Hg in flue gas by tube 1 and tube 2 was obtained on the equipment of coal combustion and sampling in lab. In order to evaluate the ability to recover and accurately quantify Hg0on the sorbent media, the analytical bias test on tube 3 spiked with Hg0was also performed and got the average recovery of 97.1%. Mercury measurements based on this method were conducted for three coal-fired power plants in China. The mercury in coal is distributed into bottom ash, electrostatic precipitator (ESP) ash, wet flue gas desulfurization (WFGD) reactant, and flue gas, and the relative distribution varied depending on factors such as the coal type and the operation conditions of plants. The mercury mass balances of three plants were also calculated which were 91.6%, 77.1%, and 118%, respectively. The reliability of this method was verified by the Ontario Hydro (OH) method either in lab or in field.

Physical Effects

The beneficial influences of gypsum on soil improvement and plant growth have been well-documented, Among these benefits are reclamation of sodic soils, alleviation of subsoil acidity problems, and contribution of Ca and S as nutrients. There are three industrial byproducts that contain significant amounts of gypsum. Phosphogypsum is probably the best-known byproduct gypsum source; the others are clean-air technology coal combustion byproducts, namely fluidized bed combustion and flue gas desulfurization residues. This review summarizes the beneficial chemical and physical effects of gypsum on soil properties and the resultant benefits on plant growth. Where applicable, emphasis is placed on potential uses and limitations of byproduct gypsum sources on horticultural crops. The potential for incorporating these materials in artificial mixtures with organic materials is discussed.
