Abstract

Un proceso para la reducción de óxido de hierro a hierro metálico con el uso de gas de horno de coque (COG), que incluye: un horno hueco de reducción directa para proporcionar gas de descarte; una fuente de COG para inyectar el COG en un chorro de gas de reducción que incluye por lo menos una porción del gas de descarte; y el horno hueco de reducción directa que reduce el óxido de hierro a hierro metálico con el uso del chorro de gas de reducción y el COG inyectado. El COG tiene una temperatura de alrededor de 1.200ºC o mayor luego de la inyección. El COG tiene un contenido de CH4 de entre alrededor del 2% y alrededor del 13%. Con preferencia, el COG es COG reformado. En forma opcional, el COG es COG caliente recién preparado. La fuente de COG incluye un sistema de oxidación parcial. En forma opcional, la fuente de COG incluye un quemador de oxígeno caliente.
