Abstract
Disclosed herein are systems and methods for producing synthesis gas (syngas) using bio-oil. In some embodiments, syngas is produced by steam reforming bio-oil. In some embodiments, the bio-oil is provided in liquid form. In some embodiments at least some of the liquid bio-oil is transitioned into droplet form when entering a reformer for steam-reforming. In some embodiments, the reformer produces a gas stream comprising syngas, which may be fed to a furnace (e.g., direct reducing furnace, shaft furnace) for reducing iron ore to iron. In some embodiments, the amount of oxygen provided to the reformer is regulated based on an equivalence ratio (ER) corresponding to moles of oxygen fed to the reformer divided by moles of oxygen necessary to achieve stoichiometric combustion of the bio-oil, wherein an exemplary ER value is from about 0.1 to about 0.6.
