The direct partial oxidation of CH4 to dimethyl ether (DME) was achieved using a Pt/Y2O3 catalyst with a mixture of NO and O-2, where the NO/NO2 mixture acted as a single oxygen atom shuttle, with no decomposition or net consumption of these species.
The direct partial oxidation of CH4 to dimethyl ether (DME) was achieved with a Pt/Y2O3 catalyst using a mixture of NO and O-2. The actual gas composition contained a mixture of NO and NO2, with no decomposition or net consumption of these species. Use of O-18(2) confirmed the transfer of labeled oxygen from O-2 to CH4, indicating the NO/NO2 mixture worked as a single oxygen atom shuttle.
