摘要：

The role of nitric oxide incorporation into the reaction feed for the partial oxidation of methane to C-2-hydrocarbons and C-2-oxygenates is evaluated. The addition of NO increases the conversion of methane under all the experimental conditions studied and has a strong effect on the product distribution. Ar low NO concentration the catalysts yield mainly C2Hn hydrocarbons, but at higher NO concentrations, carbon oxides dominate. Amongst the C-1-oxygenates produced, methanol is the major compound observed and its proportion increases with increasing NO concentration. The highest C-1-oxygenates yield was 7% at atmospheric pressure.
