Comparison of activities of bulk and monolith Mn–Na2WO4/SiO2 catalysts in oxidative coupling of methane

The monoliths were prepared by coating of Al2O3 and SiO2 on the FeCrAl alloy foil and by introducing appropriate catalytically active oxides on the supports. It was found that, for both catalytic systems of monolith and bulk catalysts of Mn–Na₂WO₄/SiO₂, the dependences of methane conversion to C₂ products on the contact time virtually coincide if the normalized quantities of the active component are considered.
