Abstract
High-performance catalysts for partial oxidation (POM) and dry reforming of methane (DRM) into synthesis gas with a yield of more than 90% have been developed. The GC, XRD, SEM, TGA, and TEM methods of analysis demonstrate that the catalysts generated from presynthesized SmCoO3 and PrNi0.5Co0.5O3 materials exhibited high catalytic performance in DRM and contained nanoparticles of cobalt and nickel metals and samarium or praseodymium oxides. Due to the method employed in this study for SmCoO3 the catalyst prepared from this precursor showed higher syngas selectivity, both in DRM and POM, than catalysts with similar compositions prepared by a citrate method. It was also demonstrated that the PrNi0.5Co0.5O3 catalyst prereduced in hydrogen was more efficient in POM than the sample reduced in the reagent flow.
