High Yield Methanol Formation in a CH4-O2-NO2 Gaseous Selective Oxidation at 1 atm

Methanol and formaldehyde except for carbon oxides, nitromethane, and formic acid were obtained with high selectivities at 808K under 1 atm in a gaseous reaction of 55.6CH4-27.7O2-0.5NO2-16.2He. Selectivities to methanol and formaldehyde were 27.3% and 24.5% at the level of 10% methane conversion, respectively. The reaction route to methanol formation was addressed.
