Method For Desulfurizing Gasoline Or Diesel Fuel For Use In A Fuel Cell Power Plant

View page
US Patent:
6454935, Sep 24, 2002
Filed:
Dec 22, 1999
Appl. No.:
09/470483
Inventors:
Roger R. Lesieur - Enfield CT
Christopher Teeling - Enfield CT
Joseph J. Sangiovanni - West Suffield CT
Laurence R. Boedeker - Simsbury CT
Zissis A. Dardas - Worcester MA
He Huang - Glastonbury CT
Jian Sun - Simsbury CT
Xia Tang - West Hartford CT
Louis J. Spadaccini - Manchester CT
Assignee:
UTC Fuel Cells, LLC - S. Windsor CT
International Classification:
C10G 2906
US Classification:
208244, 208208 R, 208299, 123 1 A
Abstract:
A fuel processing method is operable to remove substantially all of the sulfur present in an undiluted oxygenated hydrocarbon fuel stock supply which contains an oxygenate and which is used to power a fuel cell power plant in a mobile environment, such as an automobile, bus, truck, boat, or the like, or in a stationary environment. The power plant hydrogen fuel source can be gasoline, diesel fuel, or other like fuels which contain relatively high levels of organic sulfur compounds such as mercaptans, sulfides, disulfides, and the like. The undiluted hydrocarbon fuel supply is passed through a desulfurizer bed wherein essentially all of the sulfur in the organic sulfur compounds reacts with the nickel reactant, and is converted to nickel sulfide, while the now desulfurized hydrocarbon fuel supply continues through the remainder of the fuel processing system.

US Patent:
6533924, Mar 18, 2003
Filed:
Feb 24, 2000
Appl. No.:
09/512035
Inventors:
Roger R. Lesieur - Enfield CT
Christopher Teeling - Enfield CT
Joseph J. Sangiovanni - West Suffield CT
Laurence R. Boedeker - W. Simsbury CT

Assignee:
UTC Fuel Cells, LLC - So. Windsor CT
International Classification:
C10G 2904
US Classification:
208244, 208208 R, 208299, 123 1 A
Abstract:
A fuel processing method is operable to remove substantially all of the sulfur present in an undiluted oxygenated hydrocarbon fuel stock supply which contains an oxygenate and which is used to power an internal combustion engine in a mobile environment, such as an automobile, bus, truck, boat, or the like, or in a stationary environment. The fuel stock can be gasoline, diesel fuel, or other like fuels which contain relatively high levels of organic sulfur compounds such as mercaptans, sulfides, disulfides, and the like. The undiluted hydrocarbon fuel supply is passed through a nickel reactant desulfurizer bed wherein essentially all of the sulfur in the organic sulfur compounds reacts with the nickel reactant, and is converted to nickel sulfide, while the desulfurized organic remnants continue through the remainder of the fuel processing system. The method can be used to desulfurize either a liquid or a gaseous fuel stream, which contains an oxygenate such as MTBE, ethanol, methanol, or the like. The inclusion of the oxygenate serves to extend the useful life of the desulfurization apparatus and method.

View page
US Patent:
7166263, Jan 23, 2007
Filed:
Mar 28, 2003
Appl. No.:
10/402808
Inventors:
Thomas Henry Vanderspurt - Glastonbury CT, US
Fabienne Wijzen - Beaufays, BE
Xia Tang - West Hartford CT, US
Miriam P. Leffler - Manchester CT, US
Rhonda R. Willigan - Manchester CT, US
Caroline A. Newman - Cromwell CT, US
Rakesh Radhakrishnan - Vernon CT, US
Fangxia Feng - Richardson TX, US
Bruce Leon Laube - South Windsor CT, US
Zissis Dardas - Worcester MA, US
Susanne M. Opalka - Glastonbury CT, US
Ying She - Worcester MA, US
Assignee:
UTC Fuel Cells, LLC - South Windsor CT
International Classification:
C01F 17/00
US Classification:
423263, 502302, 502303, 502304
Abstract:
A homogeneous ceria-based mixed-metal oxide, useful as a catalyst support, a co-catalyst and/or a getter has a relatively large surface area per weight, typically exceeding 150 m/g, a structure of nanocrystallites having diameters of less than 4 nm, and including pores larger than the nanocrystallites and having diameters in the range of 4 to about 9 nm. The ratio of pore volumes, V, to skeletal structure volumes, V, is typically less than about 2. 5, and the surface area per unit volume of the oxide material is greater than 320 m/cm, for low internal mass transfer resistance and large effective surface area for reaction activity. The mixed metal oxide is ceria-based, includes Zr and or Hf, and is made by a novel co-precipitation process. A highly dispersed catalyst metal, typically a noble metal such as Pt, may be loaded on to the mixed metal oxide support from a catalyst metal-containing solution following a selected acid surface treatment of the oxide support. Appropriate ratioing of the Ce and other metal constituents of the oxide support contribute to it retaining in a cubic phase and enhancing catalytic performance.

Chemically Assisted Surface Finishing Process

US Patent:
7229565, Jun 12, 2007
Filed:
Apr 5, 2004
Appl. No.:
10/818059
Inventors:
Mark R. Jaworowski - Glastonbury CT, US
Xia Tang - West Hartford CT, US
Clark VanTine Cooper - Glastonbury CT, US
Assignee:
Sikorsky Aircraft Corporation - Stratford CT
International Classification:
B44C 1/22
US Classification:
216 52
Abstract:
A method of surface refinement for refining a first roughness of a surface of a component to a second roughness. The method includes wetting the first roughness surface with an aqueous mixture that includes solid media. The aqueous mixture chemically alters the surface forming a chemically converted surface. Relative movement between the chemically converted surface and the solid media produces the refined second roughness.
