CATALYSEUR D'OXYDE MÉTALLIQUE DE PÉROVSKITE, DANS LEQUEL UN ION MÉTALLIQUE EST SUBSTITUÉ, POUR RÉDUIRE LE DÉPÔT DE CARBONE, SON PROCÉDÉ DE PRÉPARATION, ET PROCÉDÉ DE RÉACTION DE REFORMAGE DU MÉTHANE L'UTILISANT

摘要

The present invention relates to 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. According to the present invention, a novel type of catalyst is produced in which Ni, iron or cobalt in ionic form is substituted at a portion of the Ti site (B-site) of SrTiO
