Abstract

En diversos ejemplos de formas de realización, la presente proporciona sistemas y métodos que pueden convertir gas natural limpio o en bruto, gas de horno de coque limpio o sucio o un material similar, en gas de reducción/gas de síntesis adecuado para la reducción directa con un procesamiento o limpieza mínimos. Los hidrocarburos y similares se convierten en H₂ y CO. El azufre no afecta la conversión en gas de reducción/gas de síntesis, pero se lo elimina o limpia de algún modo por medio del lecho de hierro en el horno de cuba de reducción directa. El gas de alto horno se puede reciclar en forma continua o se puede aplicar un enfoque de única vez. Reivindicación 1: Un método para la reducción de óxido de hierro a hierro metálico, que comprende: proporcionar una corriente de gas de alto horno proveniente de un horno de cuba de reducción directa; eliminar el dióxido de carbono de la corriente de gas de alto horno con el empleo de un sistema de eliminación de dióxido de carbono; calentar la corriente de gas de alto horno en un calentador de gas para formar una corriente de gas de reducción y proporcionar la corriente de gas de reducción al horno de cuba de reducción directa para reducir el óxido de hierro a hierro metálico; y agregar una corriente de gas natural o una corriente de gas de horno de coque a la corriente de gas de reducción a modo de una corriente de gas de síntesis.
