Experiments on synthesis-gas production by partial oxidation of CH₄ over catalysts containing various amounts of Ni on SiO₂ gel are described. Catalysts were prepared by impregnating SiO₂ gel of 2-mm. size with Ni(NO₃)₂.6 H₂O solutions, drying several hours, calcining 1 hr. at 500° in an air stream, and reducing in pure H₂ 30 min. at 500°. Catalytic conversions have been carried out in an electric-tube reactor containing 25.4-29.4 cc. catalyst. The optimum conditions for the reaction were: Inlet gas rate, 1.12 liter per min., O₂:CH₄ mol. ratio 0.6 and a temperature of 850°. The optimum amount of Ni on the carrier giving no better yields of synthesis gas. Equilibrium conditions from available thermal data have been calculated and presented.
