Abstract
Se proporciona un proceso para la producción de hierro reducido directo (DRI), con o sin carbono, por el uso de hidrógeno, donde el hidrógeno se produce por el uso de agua generada internamente a partir del proceso. El proceso se caracteriza por contener uno o dos bucles de gas, uno para la afectación de la reducción del óxido y otro para la afectación de la cementación del DRI. El bucle primario responsable de la reducción recircula el gas usado del horno de eje en un bucle que incluye un paso de eliminación de polvo seco, un paso de eliminación de oxígeno para generar el hidrógeno, y una conexión al horno de eje para la reducción. En ausencia de un segundo bucle, este bucle, junto con la adición de gas natural, se puede usar para depositar carbono. Un bucle secundario de cementación instalado corriente abajo del horno de eje puede controlar más finamente la adición de carbono. Este bucle incluye un recipiente del reactor, un paso de eliminación de polvo y una unidad de separación de gases.
