A method of preparing a supported metal phthalocyanine catalyst is disclosed. A metal phthalocyanine is impregnated on a solid adsorptive support from an aqueous impregnating solution or dispersion of said metal phthalocyanine containing from about 5 to about 50 wt. ppm. morpholine. The prepared catalyst is particularly useful in the treatment of a sour petroleum distillate or fraction.

Preparation of a supported metal phthalocyanine catalyst

A process for treating a mercaptan-containing sour petroleum distillate is disclosed. The process comprises contacting said distillate with a supported metal phthalocyanine catalyst in the presence of an alkaline reagent at oxidation conditions, said catalyst having been prepared by impregnating said phthalocyanine on a solid adsorptive support from an aqueous solution or dispersion of said phthalocyanine containing from about 5 to about 50 wt. ppm. morpholine.

Process for treating a sour petroleum distillate

An improved method of treating a sour petroleum distillate is disclosed. Morpholine is admixed with the sour distillate and the distillate thereafter contacted with a metal phthalocyanine catalyst in the presence of an oxidizing agent at alkaline reaction conditions.
