  • Patent number: 8940660
    Abstract: The present invention involves both separated beds (or physical mixture) and a process for treating a fuel gas comprising sending the fuel gas to a separated bed (or physical mixture), in which the separated beds comprise a first bed of a sulfur sorbent and a second bed of a water gas shift catalyst (a physical mixture of a sulfur sorbent and a water gas shift catalyst). The process comprises first sending the fuel gas to the first bed to remove sulfur compounds from said fuel gas and then the fuel gas goes to the second bed to undergo a water gas shift reaction in which carbon monoxide is converted to carbon dioxide and water is converted to hydrogen. (or sending the fuel gas simultaneously to the physical mixture to remove simultaneously the sulfur compounds and to react CO with water to CO2 and hydrogen).

  • Patent number: 8057773
    Abstract: The invention described herein relates to a novel process that eliminates the need for post combustion CO2 capture from fired heaters (at atmospheric pressure and in dilute phase) in a petroleum refinery to achieve environmental targets by capturing CO2 in a centralized facility and providing fuel gas low in carbon to the fired heaters. It combines the pre-combustion capture of carbon dioxide with production of a hydrogen fuel source within a refinery to drastically reduce the carbon dioxide emissions of the plant. The hydrogen fuel is utilized for the process fired heaters and the fuel quality (carbon content) can be set to meet the refinery's emissions objectives. Moreover, the carbon dioxide captured can be sequestered and/or utilized for enhanced oil recovery (EOR).

  • Patent number: 7871957
    Abstract: A durable catalyst support/catalyst is capable of extended water gas shift operation under conditions of high temperature, pressure, and sulfur levels. The support is a homogeneous, nanocrystalline, mixed metal oxide of at least three metals, the first being cerium, the second being Zr, and/or Hf, and the third importantly being Ti, the three metals comprising at least 80% of the metal constituents of the mixed metal oxide and the Ti being present in a range of 5% to 45% by metals-only atomic percent of the mixed metal oxide. The mixed metal oxide has an average crystallite size less than 6 nm and forms a skeletal structure with pores whose diameters are in the range of 4-9 nm and normally greater than the average crystallite size. The surface area of the skeletal structure per volume of the material of the structure is greater than about 240 m2/cm3. The method of making and use are also described.

  • Patent number: 7833296
    Abstract: A system and process for maximizing the generation of electrical power from a variety of hydrocarbon feedstocks. The hydrocarbon feedstocks are first gasified and then oxidized in a two-chamber system and process using oxygen gas rather than ambient air. Intermediate gases generated in the system and process are recirculated and recycled to the gasification and oxidation chambers in order to maximize energy production. The energy produced through the system and process is used to generate steam and produce power through conventional steam turbine technology. In addition to the release of heat energy, the hydrocarbon feedstocks are oxidized to the pure product compounds of water and carbon dioxide, which are subsequently purified and marketed. The system and process minimizes environmental emissions.

  • Patent number: 7824455
    Abstract: A method of reducing the amount of carbon monoxide in process fuel gas in a feed stream for a fuel cell. The method includes introducing a hydrocarbon feed stream into a primary reactor and reacting the hydrocarbon feed stream in effective contact with a reforming catalyst forming primary reactor products containing hydrogen, carbon monoxide, carbon dioxide, and methane; placing a high activity water gas shift catalyst system into a water gas shift converter, introducing the primary reactor products into the water gas shift converter in effective contact with the high activity water gas shift catalyst system, and reacting the carbon monoxide and water to form carbon dioxide and hydrogen using a water gas shift reaction forming the feed stream for the fuel cell; and introducing the feed stream into the fuel cell. The high water gas shift catalyst system includes a noble metal, a support comprising a mixed metal oxide of cerium oxide and at least one of zirconium oxide or lanthanum oxide.

    Abstract: A component of a cigarette comprises a silver-based catalyst for the conversion of carbon monoxide to carbon dioxide. The silver-based catalyst comprises particles (e.g., nanoscale or larger sized particles) of metallic silver and/or silver oxide supported in and/or on metal oxide support particles. The silver-based catalyst can be incorporated into a cigarette component such as tobacco cut filler, cigarette paper and cigarette filter material to reduce the concentration of carbon monoxide in the mainstream smoke of a cigarette during smoking. The catalyst can also be used in non-cigarette applications.

  • Publication number: 20100226845
    Abstract: Hopcalite-type catalysts for oxidation of CO are formed by preparing a mixed-metal oxide precursor by firstly preparing a solution of a mixture of metal precursor compounds in a solvent, followed by contacting the solution with a supercritical antisolvent to precipitate the mixed-metal oxide precursor. A mixed-metal oxide may then be prepared from the precursor by oxidation, for example by calcination. The mixed-metal oxide is then collected and optionally activated for use as a catalyst. The activated or calcined catalyst contains a nano-structured mixed-phase composition comprising phase-separated intimately mixed nanoparticles of copper and manganese oxide.
