Abstract

Ironmaking through direct reduction of iron ore (DRI) using CO and/or H₂ significantly reduces CO₂ emissions in comparison to the traditional blast furnace route which uses coke. Fluidized bed DRI due to direct utilization of fine ore eliminates the firing/induration and cooling steps in the pelletization process used in shaft furnace DRI and blast furnace and thus has the potential to become an energy-efficient carbon neutral technology with cost competitive to shaft furnace DRI. In this paper, the commercial fluidized bed-based fine iron ore reduction technologies (FINEX, FINMET, FIOR, CIRCORED, NU-IRON, H-IRON, and IRON-CARBIDE) are reviewed. The advantages and disadvantages of the technologies are summarized, and the process conditions, energy consumptions, and DRI properties are compared. Additionally, the challenges associated with fluidizing and reducing the most widely available ultrafine ore in commercial fluidized bed technologies are addressed.

流化床中的铁矿石还原：商业技术、现状与挑战回顾

与使用焦炭的传统高炉炼铁工艺相比，使用 CO 和/或 H2 的铁矿石直接还原（DRI）工艺可显著减少二氧化碳排放量。流化床铁矿石直接还原（DRI）由于直接利用细矿石，省去了竖炉铁矿石直接还原（DRI）和高炉球团过程中的烧结/硬化和冷却步骤，因此有可能成为一种高能效的碳中和技术，其成本与竖炉铁矿石直接还原（DRI）相比具有竞争力。本文综述了基于流化床的商业精铁矿石还原技术（FINEX、FINMET、FIOR、CIRCORED、NU-IRON、H-IRON 和 IRON-CarbIDE）。总结了这些技术的优缺点，并对工艺条件、能耗和 DRI 特性进行了比较。此外，还讨论了在商用流化床技术中流化和还原最常见的超细矿石所面临的挑战。
