Abstract

Method and apparatus are described for joule boosting a SO/sub 3/ decomposer using electrical instead of thermal energy to heat the reactants of the high temperature SO/sub 3/ decomposition step of a thermochemical hydrogen production process driven by a tandem mirror reactor. Joule boosting the decomposer to a sufficiently high temperature from a lower temperature heat source eliminates the need for expensive catalysts and reduces the temperature and consequent materials requirements for the reactor blanket. A particular decomposer design utilizes electrically heated silicon carbide rods, at a temperature of 1250/sup 0/K, to decompose a cross flow of SO/sub 3/ gas.

Patent Grimes, W.P.; Bamberger, C.E.
Process for closed-cycle thermochemical production of hydrogen and oxygen from water. [uses auxiliary compounds of the system iron-chlorine]

Patent Knoche, K.F.; Schubert, J.; Schulze-Bentrop, R.

A closed-cycle multi-step thermochemical process is described for the production of hydrogen and oxygen from water. The disclosed process utilizes auxiliary compounds of the system iron-chlorine. By using the following two basic process steps: (a) reacting an iron oxide with hydrogen chloride or a mixture of hydrogen chloride and chlorine to form iron(II) chloride or iron(III) chloride, and, (b) reacting iron or iron(II) oxide with water to form iron(II) oxide or iron(II)(III) oxide, it is possible to employ a variety of additional steps so that the sum total of the reaction steps consume water, produce hydrogen and oxygen and regeneratemore »« less
Thermochemical production of hydrogen and oxygen from water. [reaction of transition metal or lanthanide compounds and a hydrogen halide]

Patent Dorrance, W.H.; Curl, R.L.

A process is disclosed which produces hydrogen and oxygen from water by means of a multi-step, closed, thermochemical cycle. Hydrogen and oxygen are produced at separate stations. Hydrogen and a halogen are produced by a sub-cycle involving transition metal or lanthanide compounds (depending on the halogen) and a hydrogen halide. Oxygen and the hydrogen halide are produced in a sub-cycle involving magnesium or transition metal compounds (depending on the halogen), the halogen and water. When the halogen is chlorine the transition metals in the oxygen producing sub-cycle can be nickel, cobalt, or yttrium and the lanthanide metals in the hydrogenmore »« less
Process for the thermochemical production of hydrogen. [sulfur-iodine cycle]

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

Hydrogen is thermochemically produced from water in a cycle wherein a first reaction produces hydrogen iodide and H/sub 2/SO/sub 4/ 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 H/sub 2/SO/sub 4/ is pyrolyzed to recover sulfur dioxide and produce oxygen.
