【Abstract】 The hydrogen production by thermochemical sulfur-iodine（SI/IS） cycle is one of the most promising methods. The optimized SI systems have been proposed by many scholars to improve the efficiency of hydrogen production. In this paper, the research status of the entire system and separated unit of these SI cycle was reviewed. The appropriate amount of water and iodine in the Bunsen reaction, phase separation, catalysis, and H₂ SO₄ and HI decomposition environment were discussed. In addition, the comparison between the experimental results and flowsheet calculations from some research groups was conducted.更多还原
