        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.
