Catalyst for selective oxidation of hydrogen sulfide gas and method for removing hydrogen sulfide using the same

摘要

The present invention relates to a catalyst for selective oxidation of hydrogen sulfide comprising cobalt oxide and a method for efficiently removing hydrogen sulfide by directly and selectively oxidizing hydrogen sulfide at a high efficiency even under the condition of presence of ammonia and water using the catalyst. 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.
