Abstract
Formaldehyde is produced by oxidising methane and/or homologous paraffin hydrocarbons in the gaseous phase with oxygen or air in the presence of a catalyst, the gaseous reaction mixture being passed through a porous fixed bed of the catalyst and then through a metal mesh adjacent to the porous bed, the mesh being formed of a transition metal of Group I or VIII of the Periodic System, or an alloy of two or more of such metals. The preferred catalyst is pumice and the mesh is preferably formed of copper, platinum, iridium, silver or gold or of an alloy of two or more of these. Oxides of nitrogen, or ammonia which is oxidised to nitric oxide during the reaction, may be added to the reaction mixture. Examples are given of the oxidation of methane and propane to formaldehyde.
