Abstract

Abstract: In order to change the KNO₃-I₂ hybrid cycle in hydrogen production from water^[1-4] into a pure thermochemical one, a subcycle consisted of equations (4)-(6) replacing theelectrochemical reaction is proposed.Reaction (6) is believed to be easy to conduct becauseof the more small solubility of K₂SO₄ than that of KI and KHSO₄ and the volatility of HI.Reaction (8) is a common one for hydrogen production in many thermochemical cycles.Reaction (7) has been investigated and a process for the reaction and sepsrstion of KNO₃ and KHSO₄ from the system is demonstrated.

Key words: hydrogen energy, hydrogen production, water, thermochemical cycle
