SELECTIVE OXIDATION CATALYST OF HYDROGEN SULFIDE INCLUDING AMMONIA AND WATER AND ITS USE FOR REMOVING HYDROGEN SULFIDE

摘要

The present invention provides a catalyst for the selective oxidation of hydrogen sulfide in which iron oxide is supported on a non-basic porous carrier, and by using the same, hydrogen sulfide can be directly oxidized with high efficiency to selectively remove hydrogen sulfide efficiently even under the presence of ammonia and water. It is about how. Since the catalyst of the present invention maintains high catalytic activity even in the presence of ammonia and water, hydrogen sulfide generated in a large amount in oil refineries or steel mills can be easily removed with non-toxic elemental sulfur or ammonium sulfate. Environmental pollution problems can also be solved.
