The selective oxidation of hydrogen sulfide was studied over Zeolite X catalysts(Zeolite HX, LiX, NaX, KX) that were prepared by ion exchange method. The acidity sequence of modified Zeolite X catalyst was as follow, Zeolite HX >Zeolite LiX> Zeolite NaX >Zeolite KX.The basicity sequence was reverse of acidity one. For the same conditions (reaction temperature: 225?? space velocity: 20000h^-1), the conversion of hydrogen sulfide was decreased in Zeolite KX > Zeolite NaX > Zeolite LiX > Zeolite HX order. It was determined that the selective oxidation of hydrogen sulfide was influednced by acidity and basicity. In case of Zeolite NaX catalyst, the yield of element surfer 90% can be obtained at reaction temperature(200), the ratio of O2/H2S (0.5).
