  • 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: 9808793
    Abstract: Differing from the startup temperature of partial oxidation of butane (POB) reaction stimulated by conventional rhodium-based or nickel-based catalyst reaches 700° C. or above, the present invention particularly discloses a novel catalyst consisting of fluorite-type oxide support and Ni active metal for being applied in hydrogen production by low temperature partial oxidation of light hydrocarbon (POLH), so as to effectively reduce the startup temperature of the POLH reaction. In the present invention, the said light hydrocarbon means methane, ethane, propane, or butane. Moreover, a variety of experimental data have proved that this novel catalyst makes the startup temperature of POB reactions be lowered to 250° C. On the other hand, the experimental data have also proved that, the carbon deposition formed on the catalyst during POB reaction can be obviously improved after adding a few amount of platinum into the constituting ingredients of the novel catalyst.

  • 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.
