Hydrogen Peroxide Scrubber for the Control of Nitrogen Oxides

Simultaneous removal of SO2, NO and Hg0 by wet scrubbing using urea + KMnO4 solution

“…So, most of the researchers have focused on the oxidation technology, and wish to efficiently remove Hg 0 , SO 2 and NO simultaneously in the WFGD. The most commonly used oxidants include K 2 S 2 O 8 [17], KMnO 4 [18,19], Fenton's reagent [20,21], NaClO 2 [12,22], O 3 [5], H 2 O 2 [23,24], ClO 2 [25] and so on.…”

Emission characteristics of Cl2 and ClO2 during simultaneous removal of SO2 and NO using NaClO2 solution

“…Recently, some oxidations including KMnO 4 [4] , S 2 O 8 2- [5] , Fenton's reagent [6,7] , H 2 O 2 [8] , ClO 2 [9] , NaClO [10,11] have already been used as additives in absorption liquid of WFGD system to achieve simultaneously desulfurization and denitrification purpose. Among them, NaClO 2 is one of the most potential reagent can be used in the field of simultaneously SO 2 and NOx removal.…”

Reduction of hexamminecobalt (III) catalyzed by coconut activated carbon

“…pH affects the reaction greatly. A best Co(NH 3 ) 6 31 conversion is obtained at pH of 2.74. A high temperature is favorable to such reaction.…”

“…The hexamminecobalt (II), Co(NH 3 ) 6 21 , is the active constituent in the removal of nitric oxide with the hexamminecobalt ammonia solution. To maintain the capability of removing NO with the hexamminecobalt solution, activated carbon is used to catalyze the reduction of hexamminecobalt (III) to hexamminecobalt (II).…”

“…A high temperature is favorable to such reaction. The reaction is first order with respect to Co(NH 3 ) 6 31 . The intrinsic activation energy of 56.…”
