Abstract
A series of molybdena based catalysts have been tested for the selective oxidation of methane at ambient pressure, with N2O as oxidant. Formaldehyde was produced over molybdena on silica and sodium treated silica but use of other supports, such as TiO2 or MgO resulted in total oxidation products only being produced. An optimum molybdena loading was observed with the silica support. Optimum selectivity was observed at low contact times and temperatures below 500C. A series of radical reactions is proposed to explain the selectivity towards formaldehyde and the absence of methanol in the selective oxidation products.
