摘要
Catalysts for the Catalytic Partial Oxidation (CPO) of methane to synthesis gas. The fundamental component of the catalyst is the perovskite structure ÄAzA'1-zÜÄB1-x-yNixRhyÜO3-d obtained using La, Sr, A and A' cation sites (A, A': actinide and/or lanthanide, elements and/or elements from Group I and II) and mainly Fe, Ni, as B cation sites (B: transition metal element and/or element from Group III to V). The active phases Ni and/or Rh are inserted in the perovskite structure during the preparation and are reduced in situ or before the catalytic tests. The insertion of the Rh and Ni in the perovskite structure allows an high dispersion of the metal on the surface and increases its interaction with the perovskite matrix ensuring high activity and stability.
