Title
Support material variation for the MnxOy-Na2WO4/SiO2 catalyst
Abstract

•SiO2 appears to be the best support material for MnxOy-Na2WO4.•SiC, TiO2-rutile and Fe2O3-based support materials are possible alternatives.•They have better active sites, but in lower numbers.•Thus, optimized preparation procedures could result in promising improvements in catalytic performance.

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 C2 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.
