Abstract

Es un procedimiento para la reducción directa de material granular que contiene hierro en un procedimiento por lecho fluidizado se libera gasreformado al menos parcialmente de CO2, se alimenta como gas reductor a una zona de reducción porle cho fluidizado, se extrae de la misma como gas decabeza y se mezcla dicho gas de cabeza al menos en parte con gas reformado para la reducción directa. Para ahorrar en las piezas de la disposición queestán afectadas por el gas reductor y paralog rar ahorros en los costos de calefacción, se remueve CH4 y N2, en adición de CO2, al menos parcialmente poradsorción de 50 a 100% de gas reformado y 0 a 100% de gas de cabeza, y siendo el gas de cola removido por adsorción del gasreformado y/ o gas de cabeza yutilizado como gas para calefacción.
