Abstract

A composition and method for a Catalytic Partial Oxidation (CPO) of methane to synthesis gas. The catalyst allows the process to proceed at low residence time providing a long time thermal stability. The perovskite structure [AzA′1-z][B1-x-yNix Rhy] O3-δ of the catalyst is obtained using mainly La, Sr, as 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).
