specific Embodiment

[0067] Set the hydroiodic acid electrolysis parameter t + is 0.95, β is 3, and the effective area of ​​the membrane is 0.0025m 2 , the current density is 1.01A / cm 2 . Design and introduce the sulfur-iodide cycle hydrogen production process after the introduction of hydroiodic acid electrolysis, as shown in the attached figure 2 Shown, including the Bunsen reaction unit, sulfuric acid decomposition unit and hydroiodic acid electrolysis unit. The feed to the Bunsen reaction consists of H 2 O, HI, SO 2 , I 2 , and its corresponding feed ratio is n(H 2 O):n(HI):n(SO 2 ):n(I 2 )=58.96:4.16:32.67:4.21. With the goal of hydrogen production of 10L / h, the ELECNTRL method is used globally. The calculated material balance results of the above three units are shown in Table 6-8.
