ABSTRACT:
This invention relates to a catalytic composite effective in oxidizing mercaptans contained in a sour petroleum distillate to disulfides. The catalytic composite comprises a metal chelate, an onium compound and optionally an alkali metal hydroxide. The onium compound may be selected from the group consisting of phosphonium, arsonium, stibonium, oxonium and sulfonium compounds, with phosphonium, oxonium and sulfonium compounds preferred. Additionally, metal phthalocyanines are a preferred class of metal chelates. This invention also relates to an improved process for treating a sour petroleum distillate, wherein the improvement comprises using the catalytic composite described above.
