Process for the thermochemical production of hydrogen

Patent Norman, John H.; Russell, Jr., John L.; Porter, II, John T.; ...

Hydrogen is thermochemically produced from water in a cycle wherein a first reaction produces hydrogen iodide and H₂SO₄ by the reaction of iodine, sulfur dioxide and water under conditions which cause two distinct aqueous phases to be formed, i.e., a lighter sulfuric acid-bearing phase and a heavier hydrogen iodide-bearing phase. After separation of the two phases, the heavier phase containing most of the hydrogen iodide is treated, e.g., at a high temperature, to decompose the hydrogen iodide and recover hydrogen and iodine. The H₂SO₄ is pyrolyzed to recover sulfur dioxide and produce oxygen.

Carbonate thermochemical cycle for the production of hydrogen

Patent Collins, Jack L [Knoxville, TN]; Dole, Leslie R [Knoxville, TN]; Ferrada, Juan J [Knoxville, TN]; ...

The present invention is directed to a thermochemical method for the production of hydrogen from water. The method includes reacting a multi-valent metal oxide, water and a carbonate to produce an alkali metal-multi-valent metal oxide compound, carbon dioxide, and hydrogen.

Thermochemical generation of hydrogen and oxygen from water

Patent Robinson, Paul R [Knoxville, TN]; Bamberger, Carlos E [Oak Ridge, TN]

A thermochemical cyclic process for the production of hydrogen exploits the reaction between sodium manganate (NaMnO.sub.2) and titanium dioxide (TiO.sub.2) to form sodium titanate (Na.sub.2 TiO.sub.3), manganese (II) titanate (MnTiO.sub.3) and oxygen. The titanate mixture is treated with sodium hydroxide, in the presence of steam, to form sodium titanate, sodium manganate (III), water and hydrogen. The sodium titanate-manganate (III) mixture is treated with water to form sodium manganate (III), titanium dioxide and sodium hydroxide. Sodium manganate (III) and titanium dioxide are recycled following dissolution of sodium hydroxide in water.
