Partial oxidation of methane over silica- and alumina-supported vanadia catalysts
A considerable effort has been made to study catalysts which are active and selective for the partial oxidation of methane to oxygenates primarily because of the need to convert surplus natural gas, mainly methane, to value added products. Among the catalysts active and selective for partial oxidation, supported vanadia and molybdena catalysts have been shown to be the most promising. Although there have been a number of studies reporting on the influence of different vanadia species on the activity and selectivity for the partial oxidation of higher hydrocarbons, including ethane, such investigations have not yet been made for the partial oxidation of methane. In a companion article, the authors reported on the nature of the vanadium species and the dispersion of vanadia found on V[sub 2]O[sub 5]/SiO[sub 2] and V[sub 2]O[sub 5]/Al[sub 2]O[sub 3] catalysts as determined by TPR and solid-state [sup 51]V NMR. In this note, the authors report on the influence of the nature of these species and the effect of vanadia dispersion on the activity and selectivity for the partial oxidation of methane. 4 refs., 4 figs., 2 tabs.
