  • Steam reforming catalyst
    Patent number: 11819831
    Abstract: A Ni-based steam reforming catalyst having excellent carbon deposition resistance and sintering resistance is provided. The steam reforming catalyst is constituted by including nickel as a catalytically active metal, lanthanum as a first co-catalyst component, manganese as a second co-catalyst component, and a carrier containing ?-alumina as a main component.

  • POROUS ALUMINA AND CATALYST
    Publication number: 20230105883
    Abstract: Porous alumina having excellent heat resistance and coking resistance is provided. The porous alumina can include silica and barium oxide added to aluminum oxide, wherein a ratio of SiO2 addition amount to a total mass of aluminum oxide and SiO2 addition amount is defined as SiO2 addition ratio (mass %), a ratio of BaO addition amount to a total mass of aluminum oxide and SiO2 addition amount is defined as BaO addition ratio (mass %), when the SiO2 addition ratio is within a range of 3 mass % or less and the BaO addition ratio is within a range of 14 mass % or less, the silica and the barium oxide are respectively added to the aluminum oxide so that a specific surface area of the porous alumina measured by a measuring method after heat treatment is equal to or larger than a reference specific surface area of reference porous alumina.
