Claim 1
Independent Claim
123 words
IN A PROCESS WHEREIN METALIC OXIDE IS REDUCED TO A LOWER STATE OF OXIDATION IN A REDUCTION ZONE AT TEMPERATURES RANGING FROM ABOUT 1200*F. TO ABOUT 1800*F. BY CONTACT OF SAID OXIDE WITH A CARBON MONOXIDE-CONTAINING GAS TO PARTIALLY OXIDIZE SAID CARBON MONOXIDE GAS TO PRODUCE AN EFFLUENT GAS CONTAINING UNREACTED CARBON MONOXIDE AND CARBON DIOXIDE, THE STEPS COMPRISING WITHDRAWING THE EFFLUENT GAS FROM THE SAID REDUCTION ZONE AND TREATING SAID EFFLUENT GAS WHILE THE GAS IS IN CONTACT WITH METAL, BY COOLING THE TEMPERATURE THEREOF BELOW ABOUT 900*F. AND THROUGH THE 900*F. TO 1200*F. TEMPERATURE RANGE WITHIN AN INTERVAL OF TIME RANGING FROM ABOUT 0.5 TO 5 SECONDS AND REGENERATING THE GAS BY INCREASING THE CARBON MONOXIDE CONCENTRATION RELATIVE TO THE CARBON
