Title: Method of producing hydrogen. [KNO/sub 3/ and I/sub 2/]

Abstract

Water is thermochemically decomposed to produce hydrogen by the following sequence of reactions. KNO/sub 3/ and I/sub 2/ are reacted to produce KI, NO and O/sub 2/, the NO and O/sub 2/ thus produced are reacted with water to form HNO/sub 3/, a hydrogen-containing iodide--NH/sub 4/I or HI--is formed from the HNO/sub 3/, and this iodide is thermally decomposed to produce hydrogen, all products of the reactions being recycled except hydrogen and oxygen. 2 claims, no drawings.
