Activated carbon was modified by urea, potassium hydroxide and potassium respectively. The porosity of the samples properties was analyzed by nitrogen adsorption. Then it was used as adsorbent to catalyze and absorbed H2S from the gas based on dry distillation. The experiments in this paper were carried to study the effects including H2S concentration, impregnating solutions on adsorption of H2S on the modified activated carbon. The results showed that the adsorption capacity of the modified activated carbon was relevant with the kinds of pickling liquid and experimental conditions, On the whole, The lower was concentration of H2S, the higher would adsorption capacity of modified activated carbon be. At the same time the experiments also analyzed the samples of surface oxidation products through thermogravimetric analysis.
