Patent number: 12180074Abstract: 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.Type: GrantFiled: November 6, 2023Date of Patent: December 31, 2024Assignee: Charm Industrial, Inc.Inventors: Peter Reinhardt, Shaun Kinetic, Kelly Kinetic, Jacob Wilkins, Brian Jamieson

Patent number: 12157668Abstract: A system and method of efficiently producing ultrapure hydrogen from ammonia using a single energy efficient processing step. Ammonia is introduced into reaction cells. Each reaction cell has a first tube of hydrogen permeable material that is concentrically positioned within a second tube of hydrogen impermeable material. The concentric orientation between the first tube and the second tube creates a very narrow reaction gap space between the two tubes. The reaction cell is heated to an operational temperature that is efficient for the heat cracking of ammonia and which makes the first tube highly permeable to hydrogen. Ammonia is introduced into the gap space, wherein the ammonia cracks into nitrogen and hydrogen. The hydrogen contacts the first tube and permeates through the first tube. Accordingly, the cracking of ammonia and the separation of hydrogen occurs in the same reaction cell at the same time using the same heat energy.Type: GrantFiled: April 1, 2023Date of Patent: December 3, 2024Inventor: Peter R. Bossard
