Abstract: A method of preparing a supported metal phthalocyanine catalyst is disclosed. A solid adsorptive support is impregnated with a common alcoholic solution of a metal phthalocyanine and a carboxylic acid. The impregnated support is dried to yield a catalytic composite particularly useful in the treatment of a sour petroleum distillate or fraction.

Abstract: A method of manufacturing a supported metal phthalocyanine catalyst is disclosed. An aqueous dispersion of a metal phthalocyanine comprising a soluble acid amide is prepared, and a solid adsorptive support contacted therewith at conditions to adsorb at least a catalytic amount of said metal phthalocyanine thereon. The resulting composite is subsequently dried.

Abstract: A process is disclosed for the catalytic oxidation of mercaptans in a sour petroleum distillate containing difficultly oxidizable mercaptans, catalyst toxins and catalyst toxin precursors.

Abstract: A process is disclosed for the conversion of mercaptan compounds in a petroleum distillate which comprises contacting the petroleum distillate with caustic possessing a pH of from about 8 to a pH of about 10 to extract naphthenic acids, passing the naphthenic acid-free petroleum distillate to a charcoal bed to extract catalyst-toxin precursors and treating the resultant substantially toxin-precursor free petroleum distillate with an oxygen-containing gas atmosphere in the presence of a catalyst comprising a metal phthalocyanine compound dispersed on a solid support in a treatment medium possessing a pH of from about 9 to a pH of about 14.

Abstract: A process is disclosed for the preparation of a solid bed catalyst system which comprises treating a charcoal-containing solid support with steam and a substantially inert gas at a temperature of from about 800.degree. F. to about 950.degree. F. for a period of time comprising from about 2 hours to about 6 hours, drying the treated bed and impregnating the dried charcoal-containing solid support with from about 0.001 weight percent to about 10.00 weight percent of a metal phthalocyanine compound.

Abstract: A spent liquid catalytic phthalocyanine composite is reactivated by a method which comprises percolating said spent liquid phthalocyanine composite through a bed comprising an absorbent compound, recovering the percolated liquid catalytic phthalocyanine composite, adding a solid metal phthalocyanine compound to the recovered percolated liquid phthalocyanine composite and recovering the reactivated liquid catalytic phthalocyanine composite for reuse in organic oxidation reactions.

Abstract: A process is disclosed for the conversion of a petroleum distillate charge stock containing mercaptan, olefinic and dienic compounds comprising the treatment of said petroleum distillate in an atmosphere of an oxygen-containing gas in a medium possessing a pH of from about a pH of 8 to about a pH of 14 in the presence of a catalyst comprising a 4,4',4",4'"-cobalt phthalocyanine tetrasulfonate.
