  • Apparatus for the direct reduction of iron ores
    Patent number: 4019724
    Abstract: A process and apparatus for the gaseous reduction of sized iron ores wherein a steam-hydrocarbon fluid mixture, having a steam:carbon molar ratio ranging from 0.9:1 to 1.8:1, is catalytically reformed to produce a reducing gas mixture containing about 85% to 98% by volume carbon monoxide plus hydrogen, with a hydrogen:carbon monoxide volume ratio of at least 2:1. The reducing gas is transferred directly at elevated temperatures to a shaft furnace for reduction of ores therein, and the spent reducing gas is cleaned, cooled and dried, for use as fuel and/or cooling the reduced ores.
