Abstract
Abstract Disclosed is a catalytic composite especially useful in the treatment of sour mercaptan-containing petroleum distillates. The catalytic composite comprises a metal chelate, an alkali metal hydroxide, and a quaternary ammonium hydroxide disposed on an adsorptive support. Also disclosed is a method for treating sour mercaptan-containing petroleum distillates by contacting the distillates at oxidation conditions with the foregoing catalytic composite.
