Abstract
A catalyst is disclosed for oxidizing mercaptans to disulfides, or inorganic sulfides to elemental sulfur. The catalytic agent is a compound consisting of a metal atom bonded to a chelate such as phthalocyanine, and also to axial ligands. The compound preferably is composited on an inert granular solid support. The catalyst is an improvement over existing catalysts in that its use does not require basic agents such as caustic.
