摘要：Hydrocarbon streams such as naphtha are treated by the oxidation ofmercaptans into disulfide compounds which remain in the hydrocarbon stream. Theconversion is effected during passage of the hydrocarbon and an aqueous streamdownward through a cylindrical mass of liquid-liquid contact material (6). The liquids thenflow through a cylindrical screen (8) into an annular separation zone which surrounds alower part of the contact material. After decantation in the separation zone, the aqueousmaterial, which preferably contains the oxidation catalyst, is recycled.
