| Abstract |
Critical factors for H_2S removal of activated carbons prepared from a waste palm trunk were investigated. Two kinds of activated carbons were prepared by different methods, steam and KOH activations.... Regardless of high specific surface area and oxygen content of the KOH-activated carbon, the steam-activated carbon showed more than 11 times higher H_2S removal performance, which was even higher than a commercial activated carbon fiber. It was suggested that minerals contained in the steam-activated carbon acted effectively to remove H_2S. The results suggest a potential utilization of waste palm trunks as an available cheap precursor for the H_2S removal adsorbent.show more
