Abstract
Abstract Disclosed are a metal chelate-alkali metal hydroxide-quaternary ammonium hydroxide, catalytic composite, a method of manufacturing the catalytic composite, and a process of treating sour petroleum distillates utilizing the catalytic composite. The catalytic composite comprises a metal chelate, a quaternary ammonium hydroxide, and an alkaline metal hydroxide disposed on a molecular sieve, the alkali metal hydroxide comprising at least about 10 wt. % of the catalytic composite. The method of manufacturing the catalytic composite comprises contacting a molecular sieve with a metal chelate, a quaternary ammonium hydroxide, and a mixture of alkali metal hydroxide and at least one solvent selected from the group consisting of water and alcohols with fewer than 6 carbon atoms, the alkali metal hydroxide comprising a sufficient portion of said mixture such that said alkali metal hydroxide comprises at least about 10 wt. % of said resulting catalytic composite. The method of treating sour petroleum distillates comprises contacting the distillates at oxidation conditions with the catalytic composite described above.
