  • Patent number: 10478807
    Abstract: The invention relates to CeO2 and La2O3 for catalyzing Fe2O3—Al2O3 based chemical-looping reforming of CH4 with CO2 (CL-DRM). The reaction performance of all the composite oxygen carriers was evaluated in a fixed-bed reactor at atmospheric pressure condition. The influencing factors, including temperature and time-on-stream (TOS) were investigated. The characteristics of the oxygen carriers were checked with Brunauer-Emmett-Teller (BET) analysis and X-ray diffraction (XRD). The reducibility of the composite materials was elucidated with temperature-programmed reduction by CH4 (CH4-TPR). Preliminary experimental observations suggest that the simultaneous presence of CeO2 and La2O3 can not only enhance the reactivity of Fe2O3—Al2O3 toward CH4 oxidation and its oxygen releasing rate for fast reaction kinetics, but also improve the reactivity of its reduced form toward CO2 splitting.

  • Patent number: 10401023
    Abstract: The effects of different perovskite catalysts, catalytic active materials with a crystal structure of ABO3, on matrix stabilized combustion in a porous ceramic media are explored. Highly porous silicon carbide ceramics are used as a porous media for a catalytically enhanced matrix stabilized combustion of a lean mixture of methane and air. A stainless steel combustion chamber was designed incorporating a window for direct observation of the flame within the porous media. Perovskite catalytic enhancement of SiC porous matrix with La0.75Sr0.25Fe0.6Cr0.35Ru0.05O3; La0.75Sr0.25Fe0.6Cr0.4O3; La0.75Sr0.25Fe0.95Ru0.05O3; La0.75Sr0.25Cr0.95Ru0.05O3; and LaFe0.95Ru0.05O3, for example, were used to enhance combustion. The flammability limits of the combustion of methane and air were explored using both inert and catalytically enhanced surfaces of the porous ceramic media. By coating the SiC porous media with perovskite catalysts it was possible to lower the minimum stable equivalence ratio.

  • Patent number: 9433924
    Abstract: Mixed metal oxide catalysts (ZnO, CeO, La2O3, NiO, Al203, Si02, TiO2, Nd2O3, Yb2O3, or any combination of these) supported on zirconia (ZrO2) or hydrous zirconia are provided. These mixed metal oxide catalysts can be prepared via coprecipitation, impregnation, or sol-gel methods from metal salt precursors with/without a Zirconium salt precursor. Metal oxides/ZrO2 catalyzes both esterification and transesterification of oil containing free fatty acids in one batch or in single stage. In particular, these mixed metal oxides supported or added on zirconium oxide exhibit good activity and selectivity for esterification and transesterification. The low acid strength of this catalyst can avoid undesirable side reaction such as alcohol dehydration or cracking of fatty acids. Metal oxides/ZrO2 catalysts are not sensitive to any water generated from esterification. Thus, esterification does not require a water free condition or the presence of excess methanol to occur when using the mixed metal oxide catalyst.

The disclosed bulk powder catalyst samples include stoichiometric and non-stoichiometric Cu—Mn, Cu—Fe, and Fe—Mn spinels on Pr6O11—ZrO2 support oxide, prepared using incipient wetness method. Activity measurements under isothermal steady state sweep test condition may be performed under rich to lean condition. Catalytic activity of samples may be compared to analyze the influence that different binary spinel system bulk powders may have on TWC performance of ZPGM materials for a plurality of TWC applications. Stoichiometric Cu—Mn, Cu—Fe, and Fe—Mn spinel systems exhibit higher catalytic activity than non-stoichiometric Cu—Mn, Cu—Fe, and Fe—Mn spinel systems. The influence of prepared Cu—Mn, Cu—Fe, and Fe—Mn spinel systems may lead into cost effective manufacturing solutions for ZPGM TWC systems.

  • Publication number: 20150105242
    Abstract: Influence of a plurality of base metal loadings on TWC performance of ZPGM catalysts for TWC applications is disclosed. ZPGM catalyst samples are prepared and configured with washcoat on ceramic substrate, overcoat including doped Zirconia support oxide, and impregnation layer of Cu—Mn spinel with different base metal loadings. Testing of ZPGM catalyst samples including variations of base metal loadings is developed under isothermal steady state sweep test condition to evaluate the influence of variations of base metal loadings on TWC performance in NOX conversion. As a result of increasing Cu—Mn base metal loadings, improvements of lean NOX conversion and oxygen storage capacity may be realized at higher base metal loading ratios. The ZPGM catalyst samples exhibiting higher NOX conversion and OSC are compared with commercial PGM catalyst samples under lean condition.
