THE OXIDATION OF METHANE AT HIGH PRESSURES: III. EXPERIMENTS USING PURE METHANE AND PRINCIPALLY COPPER AS CATALYST

Mixtures of methane containing some nitrogen and oxygen were passed over copper and silver catalysts. The effects of the variables, composition of mixture pressure, and temperature were determined. From 3 to 7% of oxygen was used in various experiments at pressures from 140 to 220 atm. at a temperature of 475 °C. The effect on yields of additions of carbon dioxide to the mixture was determined.
