        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.
