Abstract

799,551. Extracting metals; iron manufacture. TEXACO DEVELOPMENT CORPORATION. Feb. 6, 1956, No. 3608/56. Classes 72 and 82(1) In a process for reducing metal oxide to metal in which a down-flowing bed of oxide is met by an up-flow of carbon monoxide and hydrogen whilst part of the resulting gas mixture is withdrawn at an intermediate point (21) in the bed and air is admitted to the bed above that intermediate point (at 18) for combustion of the remaining monoxide and hydrogen, nitrogen is also introduced to the bed above said intermediate point (at 24), and preferably below the air admission point, to ensure the temperature of the upper portion of the bed being below the.sintering temperature of the oxide. The process is said to be applicable to the production of Ni, Cr, V, Ti, and especially iron, a "sponge" metal being produced. The withdrawn gas mixture may be treated (at 22 and/or 14) to remove CO 2 and water vapour and the residual CO and hydrogen reintroduced into the lower part of the bed. As described for producing iron, oxide ore is admitted into furnace 12 at 16, preheated CO-hydrogen mixture at 11, air at 18, and nitrogen at 24. An air fractionator 5 supplies the nitrogen and also oxygen which is led along line 6 to a gas generator 7. There the oxygen pre-heated to 300‹F. is mixed with natural gas (or similar fuel) led in at 8 and which has been pre-heated to 1000‹F., the resulting CO- hydrogen mixture being treated if necessary at 13 for removal of sulphur and at 14 for removal of steam and CO 2 and led along line 11. CO 2 from the line 21 and separator 14, may also be led via 9 and 15 to the generator 7. Iron sulphide from separator 13 may be added to the ore at 16. The CO-H mixture should contain more than one and preferably two or three volumes of CO per volume of H 2 , and it is pre-heated to enter the furnace at 1750‹F. The gas mixture withdrawn at 21 is at about 1500‹F., whilst in the upper zone of the furnace the temperature of the ore is maintained at between 1400 and 2000‹F. Iron sponge is discharged at 17.
