Recovery of H_2S in coke oven gas as elemental sulfur and ammonium sulfate by catalytic oxidation

摘要

This study is related to the selective catalytic oxidation of H_2S in the presence of excess water and ammonia using V_2O_5/SiO_2 catalyst.Hydrogen sulfide was successfully converted to the mixture of elemental sulfur and ammonium thiosulfate without considerable sulfur dioxide emission.Plausible reaction steps are proposed to describe the kiinetic experimental results.
