In the steel industry, H2S in the coke oven gas is scrubbed and concentrated using aqueous ammonia. Concentrated H2S that is separated from aqueous ammonia is transferred to Claus plant to convert it into elemental sulfur, and remaining aqueous ammonia is generally incinerated. However, the separation of H2S from the aqueous ammonia is not perfect. Remaining aqueous ammonia stream contains typically about 2% H2S which in turn results in the SOx emission problem during the incineration. In this case, the control of SOx emission is difficult because the stream contains not only excess water vapor but also high concentration of ammonia gas. In this study, we provides on catalyst for selective removal of H2S in the stream containing both of ammonia and water. Hydrogen sulfide in the stream containing water vapor and ammonia was completely converted to the mixture of ammonium sulfate and elemental sulfur without sulfur dioxide emission. This gives the new solution for treatment of emission gas which released from coke oven in steel production.
