Study on the wet catalytic oxidation of H2S to sulfur by Fe/Cu catalyst
Fe/Cu体系湿式催化氧化一步高效脱除H2S新方法研究

The wet catalytic oxidation under room temperature was invented with new type catalyst for H2S removal, and the reaction mechanism, experimental condition and process diagram were also investigated. Not only the effects of the concentrations of Fe3+,Cu2+ and the inlet concentration of H2S on the removal efficiency of H2S, but also the effects of the concentrations of Fe3+, H+ and added agent NaCl on the oxidizing rate of CuS were studied. Furthermore the comprehensive experiments were established, and the results showed that the removal efficiency of H2S could reach 100%. The removal of H2S, production of sulfur and regeneration of Fe3+,Cu2+ could be accomplished in one equipment at the same time, when 5% O2 was in exhaust gas under the conditions that the concentrations of Fe3+, Cu2+ were 40g?L-1 and 80g?L-1 respectively in the absorbing agent. None raw material will be consumed except O2 in the flue gas and the process has no secondary pollution and no problem of degradation.
