Transient kinetic studies were performed for the partial oxidation of methane to methanol on silica-supported vanadium oxide at 2 wt% vanadium oxide. The transient experiments were performed by removing a reactant abruptly from the reactor feed which normally consisted of CH[sub 4], N[sub 2]O, O[sub 2], and H[sub 2]O. For a number of cases, a small amount of methanol was added into the reactor feed to investigate whether methanol was oxidized on the catalyst. It was found that the formation of CH[sub 3]OH, HCHO, and CO followed two different reaction pathways, parallel and sequential pathways, and required different forms of oxygen species. N[sub 2]O was much more active than O[sub 2] for the activation of methane. O[sub 2] converted CH[sub 3]OH to HCHO but not to CO while N[sub 2]O converted CH[sub 3]OH to CO but not to HCHO. Water vapor was found to block the formation of HCHO and CO but have no effect on the formation of CH[sub 3]OH.
