        Experiments were made by a flow method at 800°-1,000° with and without catalysts on CH₄-air and CH₄-O₂ mixtures.  Ni and Co were efficient catalysts and their activity was promoted by adding various oxides.  The most efficient catalysts of those studied were Ni-ThO₂ and Ni-SiO₂.  In the presence of these catalysts the reaction, 2 CH₄+O₂=2 CO+4 H₂, proceeds almost quantitatively at 850°-900°.  Without catalysts most of the CH₄ remains unchanged at 1,000°.
