摘要：

The catalytic performance of some metal oxides in the selective oxidation of H2S in the stream containing water Vapor and ammonia was investigated in this study. Among the catalysts tested, Co3O4/SiO2 was the most promising catalyst for practical application. It showed very small amount of SO2 emission even in the presence of excess water and ammonia. The solid product formed in the reaction was a mixture of elemental sulfur, ammonium thiosulfate and ammonium sulfate.
