摘要: H.sub.2 S is directly oxidized to elemental sulfur by contacting an H.sub.2 S containing gas stream having a water content less than 10% by volume with air or oxygen over a catalyst containing at least 80 wt % titanium dioxide. Most of the H.sub.2 S in the gas is oxidized to elemental sulfur. The process is especially useful for recovery of additional sulfur from effluent gas from a Claus unit.
