摘要： A catalyst for recovering elemental sulfur by the selective oxidation of hydrogen sulfide is represented by the following chemical formula: VaTibXcOf wherein, a is such a mole number that vanadium amounts to 5-40% by weight based on the total weight of the catalyst; b is such a mole number that titanium amounts to 5-40% by weight based on the total weight of the catalyst; X is an element selected from the group consisting of Fe, Mn, Co, Ni, Sb and Bi; c is such a mole number that X amounts to 15% by weight or less based on the total weight of the catalyst; and f is such a mole number that oxygen is contained to the final 100% by weight. The catalyst can recover elemental sulfur at high rates for a long period of time without being deteriorated in activity. The high catalytic activity is maintained even when excess water is present in the reaction gas.
