Catalytic Performance of Calcium-Lanthanum co-doped Ceria (Ce0.85-xLa0.15CaxO2-δ) in Partial Oxidation of Methane

Abstract

In this study, Ce0.85-xLa0.15CaxO2-δ was synthesized using sol-gel combustion method and applied for partial oxida-tion of methane (POM). The physicochemical properties of catalyst were analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and thermogravimetric analysis (TGA). Material shows a pure cubical structure and is highly stable up to 850 °C. The performance testing indicat-ed the conversion of CH4 is 65% and selectivity of H2 and CO are 28% and 8%, respectively. The performance indi-cated the catalyst has a potential to be used for partial oxidation of methane on a larger scale.
