摘要： An improvement in a method for the batchwise gaseous reduction of metal oxides, e.g., iron ore, to metals, e.g., sponge iron, in a multiple unit reactor system of the type in which separate bodies of metal-bearing material are simultaneously treated in one or more reduction reactors and cooling reactors. Reduction is effected with a gas composed largely of carbon monoxide and hydrogen generated by the catalytic conversion of methane and steam at an elevated temperature. Improved cooling is obtained by first feeding the freshly prepared gas to a reduction reactor rather than a cooling reactor, thereby minimizing formation of methane in the cooling reactor. In a modified embodiment, methane is fed to the cooling reactor and at least a portion of the effluent gas is recycled through the catalytic reformer.

摘要： An improvement in a method for the batchwise gaseous reduction of metal oxides, e.g., iron ore to metals, e.g., sponge iron, in a multiple unit reactor system of the type in which separate bodies of metal-bearing material are simultaneously treated in one or more charging reactors, reduction reactors and cooling reactors and a reducing gas is passed successively through the cooling and reduction reactors. The reducing gas is recirculated in both the cooling reactor and the reducing reactor to increase the mass flow rate of the gas. By recycling the gas to the reduction reactor acceptable reduction can be achieved in a shorter period of time and with a single reactor. Also the temperature gradient through the bed is reduced thus producing a higher average temperature in the bed for a given inlet temperature and more nearly uniform metallization is obtained.

摘要： A method and apparatus is disclosed for achieving improved reduction efficiency in the reduction of particulate metal ores, e.g., iron ore, in a vertical shaft, moving bed reactor having a reduction zone in which a hot reducing gas is caused to flow through a portion of the ore bed to reduce the metal ore thereof to metal, e.g., sponge iron. The improved efficiency is achieved by using a split-flow of reducing gas to the reduction zone of the reactor. In one embodiment of the invention separate reducing gas streams are supplied to the top and bottom of the reduction zone and combined near the center of the reduction zone and removed from the reactor. In another embodiment of the invention reducing gas is fed to a point near the center of the reduction zone, caused to flow both upwardly and downwardly through the ore in the reduction zone and removed at points near the top and bottom of the reduction zone. By using the disclosed split-flow systems, the residence time of the metal-bearing material within the reactor can be reduced and the productivity of the reactor thereby increased.
