Direct conversion of methane to methanol and formaldehyde over a double-layered catalyst bed in the presence of steam

Article abstract of DOI:10.1039/cc9960000663

Using a double-bed reactor configuration with an up-stream 1 mass% SO₄^2-/1 mass% SrO/La₂O₃ catalyst to generate methyl radicals and a down-stream 1 mass% V₂O₅/SiO₂ catalyst to stabilize the methyl radicals for reaction to form hydrolysable methoxide species, the methanol and formaldehyde space-time yields are increased up to five-fold for partial oxidation of methane in the presence of air and steam at moderate temperatures of 550-600°C as compared with the single-bed 1 mass% V₂O₅/SiO₂ catalyst, while little of these oxygenates are formed over a mechanically mixed catalyst bed.
