Thermochemical water splitting cycles are recognized as one of the promising pathways for sustainable hydrogen production. In the present study, Iron-chlorine (Fe–Cl) cycle as one of the chlorine family thermochemical cycles where iron chloride is consumed for hydrogen production from water, is considered for a study. This four-step cycle is modelled by Aspen Plus software package and analyzed for performance investigation of each reaction step and system's components. The parametric studies are also performed to assess the effect of operation conditions such as temperature, pressure and steam to feed ratio on the reaction products and conversion rates. Results indicated that although the effect of pressure is not significant on reaction's production rates, an increase in temperature favors oxygen production in reverse deacon reaction and magnetite production in hydrolysis and lowers hydrogen production in the hydrolysis step. On the other hand, steam to chlorine (Cl₂) ratio is directly correlated with hydrochloric acid (HCl) and oxygen production in reverse deacon reaction and hydrogen production in hydrolysis.

热化学水分解循环被认为是可持续制氢的有前途的途径之一。在本研究中，考虑将铁-氯（Fe-Cl）循环作为氯族热化学循环之一，其中消耗氯化铁以从水中生产氢气。该四步循环由Aspen Plus软件包建模，并进行了分析，以研究每个反应步骤和系统组件的性能。还进行了参数研究，以评估操作条件（如温度，压力和蒸汽进料比）对反应产物和转化率的影响。结果表明，尽管压力对反应产率的影响不大，温度的升高有利于在逆执事反应中产生氧气，而在水解中有利于磁铁矿产生，并且在水解步骤中有利于氢产生。另一方面，蒸成氯气（Cl₂）比率与逆执事反应中的盐酸（HCl）和产氧量以及水解中的产氢量直接相关。
