SYSTEMS AND METHODS FOR SELF-REDUCTION OF IRON ORE

Abstract: disclosed herein, in some aspects, are systems and methods for producing a material comprising iron through self-reduction of iron ore using bio-oil and/or other reducing agents (e.g., bio-based reducing agents), such as biocrude, ethanol, or other bio-based liquids or biologically sourced liquids. the bio-oil and/or other reducing agents can be mixed with the iron ore to form a furnace mixture, which can be heated, such that the components of the bio-oil and/or other reducing agents in the furnace mixture reduce the iron ore to form an iron product (e.g., a material that includes metallic iron). in some cases, the pre-formed furnace mixture allows for the reducing agents to interact with the iron more readily, thereby providing for quicker reaction rates, and thereby quicker reduction of iron ore, as compared to direct reduction iron production.
