核能制氢是大规模高效生产无二氧化碳氢气的最有前景的方法之一。在位于中国的清华大学核能与新能源技术研究所，从2005年开始进行核制氢的研发。介绍了近10年来碘-硫(IS)法核制氢的进展，重点介绍了HI/I2/H_2SO_4/H_2O体系的本森反应和分离特性、H_2O和硫酸的提纯、电渗析电堆的发展以及HI和SO_3分解所用催化剂等基础研究的进展。在实验结果的基础上，建立并验证了关键单元和整个IS过程模拟的方法学和半经验模型。此外，还建立了两个旨在验证概念的信息系统设施，并进行了综合实验室规模的信息系统流程演示。然后在这些装置上成功地进行了闭路循环试验，从而证实了该工艺的可行性和可控性。最后，介绍了核氢的未来发展计划。
Nuclear hydrogen production is one of the most prospective methods of efficiently producing CO2-free hydrogen in large scale. In the Institute of Nuclear and New Energy Technology of Tsinghua University in China, research and development on nuclear hydrogen production have been conducted since 2005. This paper presents the progress of nuclear hydrogen production through the iodine–sulfur (IS) process over the past 10 years, including highlights of fundament studies such as the Bunsen reaction and separation characteristics of the HI/I2/H2SO4/H2O system, the purification of HIxand sulfuric acid phases, the development of electro–electrodialysis stacks for HI acid preconcentration, and the catalysts used for HI and SO3decomposition. Based on the experimental results, the methodology and semi-empirical models for the simulation of key units and the entire IS process were established and verified. Furthermore, two IS facilities aimed at proof-of-concept was created, and an integrated laboratory-scale demonstration of IS process was performed. Closed-cycle experiments were then successfully conducted on these facilities, thereby confirming the feasibility and controllability of the process. Finally, a future plan for nuclear hydrogen was introduced.
