Abstract
La présente invention concerne un procédé permettant la réduction directe de matériaux contenant de l'oxyde de fer au moyen d'un gaz réducteur contenant du CO et du H¿2? dans au moins une zone de réduction à lit fluidisé, le gaz réducteur utilisé sortant de la/des zone(s) de réduction et contenant du CO¿2? étant recyclé, et le gaz de réduction recyclé, obtenu par reformage du CO¿2? du gaz de réduction utilisé, et d'un gaz contenant du méthane, en particulier du gaz naturel, est produit. Dans ledit procédé, le reformage du CO¿2? et la réduction directe sont réalisés à une pression d'au moins 4 bar de surpression, ce qui permet d'éviter au maximum la formation de carbone et l'apparition de dépôts, et de réduire la taille du réacteur dans lequel se trouve la zone de réduction, ladite zone de réduction contenant cependant une quantité de gaz réducteur suffisante pour répondre aux exigences de métallurgie.
