A PROCESS FOR THE SIMULTANEOUS REDUCTION OF A REDUCIBLE SOLID METAL OXIDE AND THRE PRODCTION OF CARBON MONOXIDE AND HYDROGEN WHICH COMPRISES ADMIXING SAID METAL OXIDE IN SOLID PARTICLE FROM WITH SUFFICIENT LIQUID HYDROCARBON TO FORM A SLURRY; PASSING SAID SLURRY AS A CONFINED STREAM IN TURBULENT FLOW THROUGH A TUBULAR HEATING ZONE; HEATING SAID SLURRY TO AN ELEVATED TEMPERATURE AT LEAST SUFFICIENT TO VAPORIZE SAID LIQUID HYDROCARBON DISCHARGING THE RESULTING DISPERSION COMPRISING HEATED SOLID AND HYDROCARBON VAPOR INTO A REACTION ZONE INTO ADMIXTURE WITH GAS CONTAINING FREE OXYGEN; EFFECTING INTERACTION OF SAID METAL OXIDE, HYDROCARBON AND OXYGEN IN THE REACTION ZONE AT A TEMPERATURE ABOVE ABOUT 2,000* F. AND RECOVERING FROM THE REACTION ZONE THE REDUCTION PRODUCT OF THE METAL OXIDE AND A GASEOUS PRODUCT COMPRISING CARVON MONOXIDE AND HYDROGEN.
