Catalyst for Selective Oxidation of Hydrogen Sulfide Gas Containing Ammonia and Water and Method of Removing Hydrogen Sulfide Using the Same

摘要

The present invention relates to a catalyst for selective oxidation of hydrogen sulfide in which iron oxide is supported on a nonporous porous support and, in the presence of ammonia and water, can selectively and efficiently oxidize hydrogen sulfide to efficiently remove hydrogen sulfide It is about how you are. Since the catalyst of the present invention maintains a high catalytic activity even in the presence of ammonia and water, hydrogen sulfide generated in a large amount in an oil refining plant or a steel manufacturing plant can be easily removed with nontoxic elemental sulfur or ammonium sulfate, The problem of environmental pollution can also be solved.
