        Reaction of CH4 and CO2 in various proportions at 500°-1,200° under ordinary pressure in the presence of Co or Ni catalysts was studied on experimental and semi-industrial scales for the purpose of finding the best conditions for obtaining good yields of CO and H2 with natural gas and some industrial waste gases as raw materials.  The reaction was accelerated by using good catalysts and by raising the temperature.  When there was not enough CO2, deposition of C was noticed.  This was prevented by adding steam to the mixed gas.
