Abstract

Una briqueta "verde" compactada de entre 5 cm3 y 20 cm3 que incluye, antes de la reducción en un proceso de reducción directa, una composición que incluye por lo menos 30% de material de biomasa lignocelulósica en peso seco y por lo menos 55% de finos de mineral de hierro en peso, una densidad de entre 1.4 g/cm3 y 2.0 g/cm3 y una resistencia a la compactación de por lo menos 500 N. Una briqueta de hierro de reducción directa apropiada para la producción de hierro y/o acero que incluye por lo menos 85% de hierro en peso y por lo menos 1% de carbono fijo en peso y un volumen de entre 7.5 cm3 y 30 cm3, en donde la briqueta tiene, antes de reducción (esto es, como una briqueta "verde"), la composición anterior.
