| Abstract: | A novel process of catalytic wet oxidation removal H2S from biogas with zinc/iron system was invented. The reaction mechanism, experimental apparatus and process diagram were expatiated, and the factors which have effect on the removal efficiency of H2S ,such as pH, the concentrations of zinc, ferric ions and so on were discussed. Based on them, the comprehensive experiments were done, the results showed that the removal rate were sustained above 99.6% all the time. No chemical raw materials will be consumed and the process has no secondary pollution or problem of degradation. |
