  • Publication number: 20240139718
    Abstract: The present invention is a perovskite metal oxide catalyst substituted with metal ions for reducing carbon deposition, a method for producing the same, and a process for performing a methane reforming reaction using this catalyst. The catalyst is produced in which Ni in ionic form is substituted at a portion of the Ti site of SrTiO3, MgTiO3, CaTiO3, or BaTiO3, which is a multi-component metal oxide having a perovskite structure. Then, various methane reforming reactions (steam-methane reforming, dry reforming of methane, catalytic partial oxidation of methane) may be efficiently and economically performed using this catalyst. The nickel-substituted perovskite metal oxide catalyst has a structure in which Ni2+ is substituted in the perovskite lattice structure. Thus, the metal oxide catalyst has advantages in that carbon deposition thereon does not occur, and thus, the catalyst has a high catalytic stability and may be used for a long time.
