Abstract

본 발명은 유독성 기체인 황화수소를 원소 황의 형태로 회수하기 위한 촉매 및 이를 이용한 활의 회수 방법에 관한 것이다. 산화바나듐 촉매가 구비되어 있는 반응기에, 황화수소를 함유하는 유독가스와 산소가스를 공급하여 황화수소를 산화반응시키면 황화수소가 효율적으로 제거되며, 황 회수율도 높다.The present invention relates to a catalyst for recovering hydrogen sulfide, which is a toxic gas, in the form of elemental sulfur, and a method for recovering a bow using the same. When hydrogen sulfide is oxidized by supplying toxic gas containing hydrogen sulfide and oxygen gas to a reactor equipped with a vanadium oxide catalyst, hydrogen sulfide is efficiently removed and sulfur recovery rate is high.
