The influence of the addition of cobalt nickel, manganese and vanadium to active carbons on their efficiency in So2 removal from stack gases

Physicochemical properties of metal-doped activated carbons and relationship with their performance in the removal of SO2 and NO

“…This may lead to a conclusion that active material is present as CoSO 4 , as suggested by Klinik and Grzybek [5].…”

“…An enhancement of this activity is required through a proper modification of the carbon characteristics and use of additives [2]. The SO 2 removal activity enhancement for various carbons by incorporated oxides of V [3][4][5], Fe [4,6,7], Co [4,5], Ni [4,5], Mn [4,5] and Cu [8] has been reported. Meanwhile, NO reduction over carbon-based catalysts doped with oxides of V [9][10][11], Mn [11][12][13], Fe [11,14,15], Cu [14,16] and Ni [11] has been studied and promising results have been obtained.…”

Ni supported on activated carbon as catalyst for flue gas desulfurization

“…It is reported that the SO 2 adsorption characteristics of low ash active carbons are strongly influenced by the presence of certain transition metal derivatives [9]. Klinik et al [10] also studied the removal ability of SO 2 over the activated carbon loaded with Co, Ni, Mn and V and found that the generated Co(OH) 2 , Ni(OH) 2 , MnO 2 and V 2 O 3 microcrystalline could increase the desulfurization activity of activated carbon. Some authors have reported that Ca 2+ and Mo 6+ introduced to activated carbon surface can greatly promote SO 2 conversion [11].…”

Adsorption of sulfur dioxide using nickel oxide/carbon adsorbents produced by one-step pyrolysis method

“…The excellent sorption ability of these materials is linked to the catalytic action of metals, which present in various forms in the final products [22][23][24][25]. Their chemical forms along with their location on the surface are reported as important factors to govern the pollutant removal capacities.…”
