Hydrogen iodide decomposition method in thermochemical hydrogen production

摘要

PPROBLEM TO BE SOLVED: To provide such a method and apparatus for decomposing hydrogen iodide as can increase an efficiency in the decomposition of hydrogen iodide at a time of manufacturing the hydrogen by a thermochemical process. PSOLUTION: The method has the process of thermally decomposing the hydrogen iodide into hydrogen and iodine by heating the hydrogen iodide, the process of fixing the iodine formed by the thermal decomposition to a fixing agent, the process of separating from the formed hydrogen an undecomposed hydrogen iodide which is not subjected to the decomposition in the thermal decomposition, and the process of separating the iodine from the fixing agent by heating the fixed iodine.
