A PROCESS FOR MANUFACTURING A MIXTURE OF CO AND H2 WHICH COMPRISES REACTING TOGETHER IN THE FIRST STAGE IN THE PRESENCE OF A SUITABLE CATALYST A MIXTURE OF STEAM, NORMALLY GASEOUS HYDROCARBON AND CARBON DIOXIDE AT TEMPERATURES WITHIN THE RANGE OF FROM ABOUT 1300*-1500* F. AND UNDER PRESSURES OF FROM ABOUT 15-150 P. S. I. GAUGE TO FORM A PRODUCT CONTAINING CO, H2 AND CO2 AND UNCHANGED HYDROCARBON AND THEN PASSING THIS PRODUCT THROUGH AN OXIDIZING ZONE IN WHICH IS DISPOSED A PLURALITY OF SPACED BEDS OF CATALYST AND THEREIN CONTACTING THE SAID CO, H2, CO2 AND UNCHANGED HYDROCARBON WITH A FREE OXYGEN CONTAINING GAS, THUS CAUSING BURNING OF COMBUSTIBLES AND LIBERATION OF HEAT WHEREBY THE REMAINING PORTION OF THE UNCHNAGED HYDROCARBON IS LARGELY CONVERTED TO CO AND HYDROGEN, THE PROCESS BEING FURTHER CHARACTERIZED IN THAT AT LEAST A PORTION OF THE OXYGEN CONTAINING GAS IS INJECTED INTO THE OXIDIZING ZONE IN THE SPACES BETWEEN THE BEDS OF CATALYST.
