METHODS FOR PRODUCING INDUSTRIAL GASES AND CAPTURING CARBON OXIDE USING FERROUS IRON-CONTAINING MATERIALS

Resumen de: WO2025207367A1

Described are methods for producing industrial gases (e.g., hydrogen, ammonia, and/or methane) using ferrous iron-containing materials (e.g., olivine) while concurrently sequestering carbon dioxide. The process may involve mixing a ferrous iron-containing material with water and, in some examples, a reaction accelerant. The mixture may be heated to 100-300°C to initiate the oxidation of ferrous cations (Fe2+) to ferric cations (Fe3+) while reducing hydrogen (from water) and/or methane (from water and carbon dioxide, when carbon dioxide is introduced into the ferrous iron-containing mixture). In some examples, carbon dioxide may be added later (after recovering hydrogen) to form carbonates. Specifically, carbon dioxide may be injected at a high pressure (e.g., about 200 bar) post-oxidation to facilitate mineralization, using the exothermic reaction to maintain a favorable temperature. In some examples, metal complexing/chelating reagents are added to bind trace metals such as nickel, copper, cobalt, and platinum group metals for recovery.
