Abstract

La invención se refiere a un método para la reducción directa de partículas cargadas con hierro oxídico (2) a un producto de reducción (9) en un lecho fluidizado (4) a través del cual un gas de reducción (8) que contiene 30 - 100 % en moles de hidrógeno H2 fluye en flujo cruzado. Al menos 90% en masa de partículas cargadas con hierro oxídico (2) introducidas en el lecho fluidizado (4) tienen un tamaño de partícula menor que o igual a 200 micrómetros. La velocidad superficial U del gas de reducción (9) que fluye a través del lecho fluidizado (4) se establece entre 0.05 m/s y 1 m/s de manera que, para el tamaño de partícula d igual a d30 de las partículas cargadas con hierro oxídico (2) introducidas en el lecho fluidizado (4), está por arriba de la velocidad de suspensión teórica Ut y es menor que o igual a Umax.
