Abstract

La invención se refiere a un proceso para reducir óxido de hierro a hierro metálico usando un gas de horno de coque (COG), incluyendo: un horno de cuba de reducción directa para proporcionar gas de descarga; una fuente de COG para inyectar COG en una corriente de gas de reducción incluyendo, por lo menos, una porción del gas de descarga; y el horno de cuba de reduccion directa reduciendo oxido de, hierro a hierro metalico usando la corriente de gas de reduccion y COG inyectado donde el COG es tambien proporcionado en una corriente separada a una zona de transicion del horno de cuba de El COG tiene una temperatura de 1.200°C o mayor en inyección. El COG tiene un contenido de CH 4 de entre 2% en volumen y 13% en volumen Preferentemente el COG es COG reformado Opcionalmente el COG es COG con una temperatura de entre 1.000°C y 1.600°C. La fuente de COG incluye un sistema de oxidación parcial. Opcionalmente, la fuente de COG incluye un quemador de oxígeno.
