Abstract: This study examined the SO2 and NO sorption capacity of modified Palm Shell Activated Carbon (PSAC). The PSAC was modified using vanadium and cerium metal oxides and the effects were studied for simultaneous removal of SO2 and NO at temperatures of 100-300°C. The weight percentage of metal added and their calcination temperature were also analyzed. It was found that cerium based PSAC showed a higher sorption capacity compared to vanadium. Calcination procedure plays an important role in provoking the oxide formation from the impregnated metal nitrates. A 10% loading of Ce onto PSAC resulted in 121.7 mg g-1 of SO2 and 3.5 mg g-1 of NO sorption capacity g-1 of Ce/PSAC at temperature 150°C compared to vanadium which shows a much lower sorption capacity. Lower temperatures are favorable for the SO2 removal and higher temperature are favorable for NO reduction.
