摘要:
A method for operating a blast furnace and a corresponding blast furnace, the method including recovering top gas from the blast furnace, submitting at least a portion of the top gas to a recycling process, and feeding the recycled top gas back into the blast furnace, where the recycling process includes feeding the recovered top gas to a reformer unit, feeding volatile carbon containing material to the reformer unit, proceeding to flash gasification of the volatile carbon containing material in the reformer unit, at a temperature between 1100 and 1300° C., and thereby producing devolatized carbonaceous material and synthesis gas, and allowing the devolatized carbonaceous material and synthesis gas to react with the recovered top gas.
