Abstract

La invencion se refiere a un proceso para reducir material granular que contieneoxido, por mediante fluidizacion, en donde el material que contiene oxido, es mantenido en un gas de reduccion que fluye hacia arriba, en un lecho fluidizado, y es así reducido. Con el fin de evitar o reducir considerablemente las interrupciones causadas por adhesion o ensuciamiento, la velocidad del tubo vacio del gas de reduccion es continuamente reducida exclusivamente arriba del lecho fluidizado (24) sobre la seccion transversal desocupada completa (31, 32, 33) de un espacio sobre el lecho fluidizado (24), por lo que se evita la formacion de remolinos.
