Title (EN) CARBON INJECTION WITH THE CHARGED IRON OXIDE INSIDE DIRECT REDUCTION PLANT (DRP)-SHAFT FURNACES
(FR) INJECTION DE CARBONE AVEC L'OXYDE DE FER CHARGÉ À L'INTÉRIEUR DE FOURS VERTICAUX D'INSTALLATIONS DE RÉDUCTION DIRECTE (IRD)
Abstract:
(EN) Certain embodiments are directed to methods of producing direct reduced iron (DRI), the methods including contacting a target mixture comprising a solid carbonaceous reductant and an unreduced iron material (e.g., Fe2O3) with a reducing gas comprising carbon monoxide (CO) under conditions sufficient to produce reduced iron (Fe).
(FR) Certains modes de réalisation concernent des procédés de production de fer de réduction directe (FRD), les procédés comprenant la mise en contact d'un mélange cible comprenant un réducteur carboné solide et un matériau de fer non réduit (par exemple, Fe2O3) avec un gaz réducteur comprenant du monoxyde de carbone (CO) dans des conditions suffisantes pour produire du fer réduit (Fe).
