摘要
本文提出了一个硫酸中间盐子循环用以代替分解水制氢的KNO_3-I_2混合循环中的电解反应,从而使原混合循环变为一个纯热化学循环。
In order to change the KNO_3-I_2 hybrid cycle in hydrogen production from waterinto 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 K_2SO_4 than that of KI and KHSO_4 and the volatility ofHI. 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 KNO_3and KHSO_4 from the system is demonstrated.
