Study on desulfurization(H2S) capacity of activated carbon

Hydrogen sulfide is a kind of toxic and harmful gas and will pollute atmosphere environment if exhaust it directly. There are a lot of desulfurization methods so far, and the desulfurization by activated carbon is a kind of better method. The desulfurization capacity of activated carbon fiber(ACF), granular activated carbon(GAC)and power activated carbon(PAC) are studied in this paper. The results indicate that the desulfurization efficiency is ACF>powder activated carbon >granular activated carbon, the higher the packing height of ACF is, the better the desulfurization capacity of ACF. Meanwhile, the desulphurization mechanism is analyzed briefly in this paper.
