       Partial oxidation of CH₄, C₂H₆, C₂H₈, and natural gas to HCHO and HCOOH was investigated over the range 350°-650° at 739 mm. pressure.  Catalysts employed were electrolytic Cu, SiO₂ gel, CuO-SiO₂, V oxides on SiO₂, Mo oxides on SiO₂, and bronze tubing.  The yield from the oxidation of natural gas in the presence of a Mo oxide catalyst at 650° was of the order of 3%, calculated as the % of O₂ input resulting in useful product.  Data on the effects of flow rates of the various reactants in the presence of different catalysts are given.  The most active catalysts were found to be Mo oxide-SiO₂ and V oxide-SiO₂ in that order.
