    摘要: A method for the thermochemical production of hydrogen from water is disclosed in which barium iodide, carbon dioxide, ammonia and water are allowed to react with one another and give rise to barium carbonate and ammonium iodide, the ammonium iodide thus produced is thermally decomposed to produce hydrogen, iodine and ammonia, and the hydrogen thus produced is recovered as the product. The by-produced barium carbonate is allowed to react with the iodine remaining after the separation of hydrogen thereby to produce barium iodide, carbon dioxide and oxygen, and the barium iodide and carbon dioxide are recycled to the reaction system. The ammonia which remains after the separation of hydrogen is also recycled to the reaction system. By causing the by-products occurring in the various reactions to be recycled to the relevant reaction systems, hydrogen is efficiently produced from water at a reaction temperature of not more than 800.degree.
