N2 - Methane was oxidized by oxygen at temperatures as low as 473K or lower under pressurized conditions. The reaction was initialed by heated wire, which was set in the center of a pressurized reaction chamber. At the initial stage of the reaction, the methanol selectivity was as high as 90%, but its level decreased quickly with proceeding of the reaction time. When the reaction pressure was raised from 5 to 40atm, the methanol selectivity (at high O2 conversion level) was increased from 2% to 30% whereas selectivities of C2 hydrocarbons of CO2 decreased 30% to 10% or less. A new reaction model was claimed for the present reaction system.
