Abstract

Procedimiento para la reducción directa de óxidos de metal (2) usando un gas de reducción, que se basa en al menos un gas precursor, basándose al menos un gas precursor (15, 22) en gas de reformador obtenido en un reformador (3) mediante reformación catalítica de gas (4) que contiene hidrocarburo, y calentándose durante la preparación del gas de reducción al menos un gas precursor que se basa en gas de reformador por medio de energía eléctrica. Un dispositivo para la reducción directa (1) de óxido de metal (2) por medio de un gas de reducción comprende un reformador (3) catalítico para la preparación de un gas de reformador, una conducción de gas de reformador (5) para la descarga del gas de reformador del reformador (3) catalítico, una unidad de reducción (9), una conducción de gas de reducción (8) para la introducción del gas de reducción en la unidad de reducción (9), y al menos una conducción de gas precursor (6), comprendiendo al menos una conducción de gas precursor que parte de la conducción de gas de reformador un dispositivo de calentamiento de gas (7, 10, 17) eléctrico, y al menos una conducción de gas precursor (6) parte de la conducción de gas de reformador (5), y desembocando cada conducción de gas precursor (6) en la conducción de gas de reducción (8).
