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.

Abstract: Described are catalyst compositions and methods for their preparation and use. Certain catalyst compositions can include at least one reduction catalyst and at least one oxidation catalyst. A catalyst composition as described herein is useful in providing certain benefits to a combustible fuel, such as, for example, reducing harmful emissions and/or improving overall fuel economy.

Abstract: A method of reducing ammonia aerosol from manure is disclosed, which method employs an animal feed including a substantially indigestible cation exchanger capable of binding ammonium cations and an acidogenic substance to acidify an animal's manure and thereby create ammonium cations that can be bound by the cation exchanger. The method of feeding said animal feed reduces ammonia emissions from manure produced by animals fed the animal feed compared to the emissions obtained from manure when an acidogenic substance is fed alone and compared to the emissions obtained from manure when a cation exchange capacity material is fed alone.

Abstract: An animal feed is provided that employs a substantially indigestible cation exchanger capable of binding ammonium cations and an acidogenic substance to acidify an animal's manure and thereby create ammonium cations that can be bound by the cation exchanger. The animal feed reduces ammonia emissions from manure produced by animals fed the animal feed compared to the emissions obtained from manure when an acidogenic substance is fed alone and compared to the emissions obtained from manure when a cation exchange capacity material is fed alone. According to another aspect of the present invention, a method of lowering ammonia emissions from manure is provided. The present invention also provides a method for reducing soluble phosphorus levels in manure and a method for reducing total phosphorus levels in manure.

Abstract: A method of treating metal-contaminated spent foundry sand, or other industrial waste, by combining the sand with a sulfite to produce insoluble metal sulfur oxide complexes that do not leach from the sand. The treated waste may also be processed to reducing “clumping,” thereby rendering the treated waste appropriate for use in another industrial process.
