Abstract

Se provee un método para la operación de un alto horno capaz de reducir considerablemente las emisiones de CO2, y la producción estable de metal caliente durante un largo plazo usando un alto horno comercial. Un método para operar un alto horno en el cual el mineral de hierro y el coque se insertan desde la parte superior del alto horno, y en el cual el carbón vegetal pulverizado se sopla desde una tobera común, el método para operar un alto horno siendo caracterizado porque un gas que contiene hidrógeno y/o un hidrocarburo se sopla desde la botera común junto con el carbón vegetal pulverizado; y se retiran el dióxido de carbono y vapor de agua del gas de escape de la parte superior del horno del alto horno, y el gas de escape de la parte superior del horno luego se sopla en el horno desde una tobera de sección de eje.
