“…The efficiency increased with increasing plating time up to Cu-15 and then decreased in the Cu-25 despite the similar specific surface areas and total pore volumes. In conclusion, there is a strong correlation between the Cu 2 O/Cu ratio and the mercury removal properties of Cucoated porous carbonaceous materials [66]. Fig.…”

“…Hence, various materials with lower operating costs have been tested as possible alternatives to AC. In a recent study, Kim et al [66] prepared copper-coated porous carbonaceous materials (Cu/PC) using an electroless plating. They determined a strong correlation between the Cu 2 O/Cu ratio and the mercury removal properties of Cu-coated porous carbonaceous materials.…”

Public concern has recently increased over the potential risk of toxic elements emitted from anthropogenic sources. Among these, mercury has drawn special attention owing to its increasing level of bioaccumulation in the environment and in the food chain, with potential risks for human health. This paper presents an overview of research related to mercury control technology and identifies areas requiring additional research and development. It critically reviews measured mercury emissions progress in the development of promising control technologies, including catalytic oxidation, sorbent injection, photochemistry oxidation, and air pollution control devices.

“…7 Many studies have focused on the control of SDA industrial systems, while the effective removal of Hg by SDA system has not been reported yet, and the Hg removal mechanism has not been clearly explained. 8 In addition, based on the experiments of desulfurization by the SDA method, the purification of Hg and the simultaneous removal of SO 2 and Hg by the SDA method were studied. Firstly, the effect of parameter conditions on Hg removal was investigated, including the effects of lime digestion parameters, atomizer rotation speed, lime slurry pH, additives and so on.…”

BACKGROUND A novel semi‐dry method called SDA (spray drying absorption) for the simultaneous removal of mercury (Hg0) and sulfur dioxide (SO2) have been proposed in this article, in which Hg0 was initially oxidized by gaseous oxidant (O3) and liquid oxidant (K2S2O8, H2O2, and NaClO2), after which SO2 and Hg2+ were absorbed by Ca(OH)2. RESULTS The effects on different process conditions and additives on Hg0 removal were explored at first, and the results indicated that the Hg removal efficiency could be improved by oxidizing or extending the residence time of the liquid phase reaction. When SO2 and Hg coexist in the atmosphere, additives including oxidants or composite additives were added into the mixed system, and the results indicated that the best removal efficiency of SO2 and Hg was about 99.5% and 51% respectively. CONCLUSION Since SO2 has good water solubility, it would affect the oxidation of Hg and the removal of Hg. When there was nitric oxide (NO) in the atmosphere, a new stable product was generated which contributed to the removal of Hg, and the removal efficiency of SO2 and Hg was about 99.5% and 57% respectively. © 2020 Society of Chemical Industry
