| 摘 要： | 热化学循环被认为是以清洁和可持续的方式实现大规模制氢的有前途的制氢方案，对其工艺和经济性进行分析，从技术的成熟度和投资的成本等方面给出不同循环的优势和劣势具有重要的意义。从反应堆的适应性、技术的成熟度和生产规模等方面分析了不同热化学循环之间的差异，并讨论了这些方法的优缺点和面临的挑战。此外，还根据循环的热效率、制氢的成本和全球变暖潜能值（GWP），对不同的热化学循环进行了对比分析。研究结果表明，硫-碘热化学循环（SI）在热效率、成本和GWP方面都具有一定的优势，但是由于运行温度相对较高，能与之耦合的反应堆受限；硫酸混合循环（HyS）的GWP最低，但是在高温条件下面临硫酸的分解问题；铜-氯热化学混合循环（Cu-Cl），由于其运行温度较低，在反应堆耦合、低品位热量利用、制氢成本和环境影响方面都显示出巨大的潜力。

| Abstract: | Thermochemical cycle is considered as a promising hydrogen production scheme to realize large?scale hydrogen production in a clean and sustainable way.It is of great significance to analyze its process and economy，and give the advantages and disadvantages of different cycles from the aspects of technology maturity and investment cost.The difference between different thermochemical cycles from the aspects of reactor adaptability，technical maturity and production scale was analyzed，and the advantages，disadvantages and challenges of these methods were discussed.In addition，different thermochemical cycles were compared and analyzed according to thermal efficiency，cost of hydrogen production and lobal warming potential（GWP）.The research results showed that the sulfur?iodine thermochemical cycle（SI） had certain advantages in thermal efficiency，cost and GWP，but the reactor that could be coupled with it was limited due to the relatively high operating temperature.The GWP of hybrid sulfur cycle（HyS） was the lowest，but it was faced the problem of H2SO4 decomposition under high temperature conditions.Due to the low operating temperature，Cu-Cl cycle showed great potential in reactor coupling，low quality heat utilization，hydrogen production cost and environmental impact. |
