Treating a petroleum distillate with a supported metal phthalocyanine and an alkaline reagent containing alkanolamine halide

摘要

A process for treating a mercaptan-containing sour petroleum distillate is disclosed. The process comprises passing said distillate in admixture with an oxidizing agent through a fixed bed of a supported metal phthalocyanine catalyst in the presence of an alkanolamine halide, e.g., ethanoltrimethylammonium chloride, comingled with an alkaline reagent.
