  • Patent number: 10532346
    Abstract: The present invention relates to methods for producing metal-supported thin layer skeletal catalyst structures, to methods for producing catalyst support structures without separately applying an intermediate washcoat layer, and to novel catalyst compositions produced by these methods. Catalyst precursors may be interdiffused with the underlying metal support then activated to create catalytically active skeletal alloy surfaces. The resulting metal-anchored skeletal layers provide increased conversion per geometric area compared to conversions from other types of supported alloy catalysts of similar bulk compositions, and provide resistance to activity loss when used under severe on-stream conditions. Particular compositions of the metal-supported skeletal catalyst alloy structures can be used for conventional steam methane reforming to produce syngas from natural gas and steam, for hydrodeoxygenation of pyrolysis bio-oils, and for other metal-catalyzed reactions inter alia.

  • 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.
