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.

Abstract: An iron-potassium-cerium-based composite oxide catalyst, its preparation and application thereof are provided. The catalyst has metal elements Fe, K and Ce, as well as a metal element M that is at least one selected from the group consisting of Group IIA metal elements, Group VIB metal elements other than Cr and Group IVA metal elements. The catalyst has a total alkali content of 0.32-0.46 mmol/g, and a strong alkali content of 0.061-0.082 mmol/g. When used for dehydrogenation of alkyl aromatics, the catalyst shows high selectivity, high catalytic activity and high stability, provides less by-products, and has the characteristics of low material consumption and low power consumption, even at a low dehydrogenation temperature and an ultralow steam-to-oil ratio.
