摘要：The removal of hydrogen sulphide by using the activated carbon method is introduced in this paper.The desulphurization efficiency of desulphurizer is researched for different kinds of activated carbonunder laboratory conditions. It focuses on the research of the removal efficiency of hydrogen sulphideby granular activated carbon, renewable granular activated carbon, granular activated carboncontaining manganese dioxide and powdered activated carbon. The best type of activated carbonremoving hydrogen sulphide has been obtained on this basis. The results of the studies show that theprocessing efficiency of granular activated carbon is far better than that of regeneration. The more thenumber of regeneration, the worse the desulphurization efficiency. The best activated carbon ofdesulphurization efficiency is the powdered activated carbon in the experiment. After the addition ofmanganese dioxide in granular activated carbon, the desulphurization efficiency could not be improved.It is clear that manganese dioxide does not play any role.
