“…The results of the experiments performed in this study suggest that the adsorption capacity of SO 2 increases with increasing amount of water vapor. This may be due to the formation of sulfuric acid and sulfurous acid 19. The highest adsorption capacity of NO occurred when the water vapor concentration was 1 %.…”

The simultaneous adsorption of SO2, NO, and CO2 on K2CO3‐modified γ‐alumina under different operating conditions was studied in a fixed‐bed reactor. The experimental results showed that the influence of a temperature increase on the simultaneous adsorption of the three gases was complex and different from the effects seen when both chemical adsorption and competitive adsorption existed. An increase in O2 concentration and small amounts of water could enhance the adsorption of SO2 and NO while the adsorption of CO2 was not influenced. The breakthrough curves of the simultaneous adsorption experiments suggested that the investigated adsorbent may be a good candidate for the simultaneous adsorption of SO2, NO, and part of the CO2 while the adsorption capacity for CO2 still needs to be enhanced.

“…In the absence of O 2 , NO can be adsorbed on carbon surface but the adsorbed amount was small, whereas SO 2 can be adsorbed. Simultaneous removal of SO 2 and NO on Ce-modified activated carbon was studied on different operating conditions and the activity was changed in different conditions [10]. Simultaneous adsorption of SO 2 and NO on coppersupported carbon sorbents enhanced the adsorption of both SO 2 and NO compared with activated carbon, and the effect of O 2 was also investigated [9].…”

Copper‐supported activated carbon (Cu‐SAC) was studied for the simultaneous removal of SO2, NO, and CO2 in different operating conditions. The effects of Cu loading, adsorption temperature, O2 concentration, and relative humidity (RH) were studied. The experimental results showed that Cu‐SAC containing 9.8% of Cu had the best removal activity of SO2, NO, and CO2. The activity dropped with the further increase of Cu loading. Higher temperatures were not in favor of simultaneous adsorption of SO2, NO, and CO2. The performances of the removal of SO2 and NO improved obviously in the presence of O2. Water vapor could improve the adsorption performance of SO2, but higher RH was bad for the adsorption performance of SO2. The adsorption of NO and CO2 was deterred in the presence of water vapor. Cu‐SAC was shown to be a potential sorbent for simultaneous adsorption of SO2, NO, and CO2. © 2015 American Institute of Chemical Engineers Environ Prog, 34: 1044–1049, 2015

“…In particular, no study has examined the effectiveness of Ce-doped activated carbon fiber for SCR. The doping percentages and calcination temperatures were adapted from previous work (Sumathi et al, 2010). Common O 2 concentration and NOx /NH 3 levels were maintained with variations in temperature and NOx concentrations to obtain reduction efficiency profiles.…”
