    • 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.

    • 公开了一种用于从水中热化学生产氢的方法,其中使碘化钡,二氧化碳,氨和水彼此反应并产生碳酸钡和碘化铵,由此产生的碘化铵热分解产生 氢,碘和氨,并且作为产物回收由此产生的氢。 使副产的碳酸钡与氢分离后残留的碘反应,生成碘化钡,二氧化碳和氧,并将碘化钡和二氧化碳再循环到反应体系中。 分离氢后残留的氨也被循环到反应体系中。 通过使各种反应中发生的副产物再循环到相关的反应体系中,在不超过800℃的反应温度下从水中有效地产生氢。
