  • Patent number: 11654427
    Abstract: Provided is a method of manufacturing a supported catalyst and a supported catalyst manufactured using the same. The method may prevent the growth of catalytic metal particles by repeatedly applying heat, so the method is simpler and more economical than conventional processes. Moreover, since the support in the supported catalyst thus manufactured includes a hollow having a predetermined size, an electrode manufactured using the supported catalyst may ensure a desired electrode thickness even when used in a relatively small amount compared to the conventional technology. Moreover, water generated during operation of a fuel cell can be efficiently discharged, so desired mass transfer resistance can be exhibited, and a high electrochemically active surface area (ECSA) and superior catalytic activity can be attained.

  • Patent number: 9566571
    Abstract: A hexaaluminate-containing catalyst for reforming hydrocarbons. The catalyst consists of a hexaaluminate-containing phase, which consists of cobalt and at least one further element from the group consisting of La, Ba, and Sr, and an oxidic secondary phase. To prepare the catalyst, an aluminum source is brought into contact with a cobalt-containing metal salt solution, dried, and calcined. The metal salt solution additionally contains the at least one further element. The reforming of methane and carbon dioxide is great economic interest since synthesis gas produced during this process can form a raw material for the preparation of basic chemicals. In addition, the use of carbon dioxide as a starting material is important in the chemical syntheses in order to bind carbon dioxide obtained as waste product in numerous processes by a chemical route and thereby avoid emission into the atmosphere.

  • Patent number: 8968601
    Abstract: Disclosed is a catalyst used for steam carbon dioxide reforming of natural gas, wherein an alkaline earth metal alone or an alkaline earth metal and a group 8B metal are supported on a hydrotalcite-like catalyst containing nickel, magnesium and aluminum. The disclosed catalyst is useful as a steam carbon dioxide reforming (SCR) catalyst of natural gas at high temperature and high pressure, while minimizing deactivation of the catalyst due to sintering of the active component nickel and deactivation of the catalyst due to coke generation at the same time. A synthesis gas prepared using the catalyst has a H2/CO molar ratio maintained at 1-2.2. A synthesis gas having a H2/CO molar ratio of 1.8-2.2 may be used as a raw material for Fischer-Tropsch synthesis or methanol synthesis and a synthesis gas having a H2/CO molar ratio of may be used as a raw material for dimethyl ether synthesis.

  • Patent number: 8969239
    Abstract: A method of hydroprocessing a heavy hydrocarbon feedstock using a hydroprocessing catalyst having specific properties making it effective in the hydroconversion of at least a portion of the heavy hydrocarbon feedstock to lighter hydrocarbons. The hydroprocessing catalyst comprises a Group VIB metal component (e.g., Cr, Mo, and W), a Group VIII metal component (e.g., Ni and Co) and, optionally, a potassium metal component that are supported on a support material comprising alumina. The alumina has novel physical properties that, in combination with the catalytic components, provide for the hydroprocessing catalyst. The hydroprocessing catalyst is particularly effective in the conversion of the heavy hydrocarbon feedstock. The alumina is characterized as having a high pore volume and a high surface area with a large proportion of the pore volume being present in the pores within a narrow pore diameter distribution about a narrowly defined range of median pore diameters.

    Abstract: Solutions to the problem of washcoat and/or overcoat adhesion loss of ZPGM catalyst on metallic substrates are disclosed. Present disclosure provides an enhanced process for improving WCA to metallic substrates of ZPGM catalyst systems. Reduction of WCA loss and improved catalyst activity may be enabled by the selection of processing parameters determined from variation of rheological properties by the solid content of the overcoat slurry and variation of the overcoat slurry particle size distribution to produce desirable homogeneity, specific loading, and adherence of the coating on metallic substrates. Processing parameters may be applied to a plurality of metallic substrates of different geometries and cell densities.
