MnxOy,-Na2WO4/SiO2 is an active catalyst for the oxidative coupling of methane, with a remarkable stability and a suitable performance for an industrial application. MnxOy,-Na2WO4 was supported on different support materials and the catalytic activity was investigated with a parallel reactor system, allowing a direct comparison of all results. Considering the C-2 yield and the potential practical application, SiO2 is indeed the best support material for this catalyst. However, the comparison in an X-S plot with a reference MnxOy,-Na2WO4/SiO2 catalyst indicates that SiC, Fe2O3-based oxides and TiO2-rutile are also promising support materials. (C) 2014 Elsevier B.V.
