Fuel Additive

Abstract

A method for making a catalyst composition that includes a reduction catalyst mixture including a first reduction catalyst and a second reduction catalyst, wherein said first reduction catalyst comprises mixed vanadium oxides and phosphorus oxides, wherein said mixed vanadium and antimony oxides comprises V4Sb6O8, and wherein said second reduction catalyst comprises vanadium and antimony oxides; and an oxidation catalyst comprising ferrocene. The method includes selecting an organic petroleum distillate-soluble solvent that is effective to act as a reducing agent; introducing finely ground V2O5 and aqueous H3PO4 into said selected organic petroleum distillate-soluble solvent to make a first mixture; adding finely ground V/Sb oxide catalyst to said first mixture to make a second mixture; bringing the second mixture to a boil; cooling the second mixture; and adding the ferrocene or other organometallic Fe-source material to the cooled second mixture to make the catalyst composition.
